Characterization of cerebral radiation necrosis following the treatment of sinonasal malignancies.

Objectives: Our study aims to determine the incidence and potential risk factors for cerebral radiation necrosis (CRN) following treatment of sinonasal malignancies. Methods: One hundred thirty-two patients diagnosed with sinonasal malignancies over an 18-year period were identified at two institutions. Forty-six patients meeting inclusion criteria and treated with radiation therapy were included for analysis. Demographic and clinical-pathologic characteristics were collected and reviewed. Post-treatment magnetic resonance imaging (MRI) at least 1 year following treatment was reviewed to determine presence or absence of CRN. Results: CRN was identified on MRI in 8 of 46 patients (17.4%) following radiation treatment. Patients with a history of reirradiation were more likely to develop CRN (50% vs. 10.5%, p < .05). The BEDs of radiation were also higher in CRN patients compared to non-CRN patients, but this difference was not significant (p > .05). CRN patients had a higher proportion of tumors with skull base involvement than non-CRN patients (100% vs. 57.9%, p = .037). Demographics, comorbidities, pathology, primary tumor subsite, chemotherapy use, and stage of disease demonstrated no significant increase in risk of CRN. Conclusions: Reirradiation and tumor skull base involvement were significant risk factors associated with CRN. Higher average total prescribed and BEDs of radiation were seen in the CRN groups, but these differences were not statistically significant. Gender, comorbidities, tumor subsite, tumor location, and treatment type were not significantly different between groups. Level of evidence: Level 3.

The Big Squeeze: Factors Contributing to Moral Distress Among Radiologist Clinician-Educators.

Moral distress is a term used to describe the cognitive-emotional dissonance that is experienced when one is compelled to act contrary to one's moral requirements. This occurs as a result of systemic constraints that prevent an individual from taking actions that they perceive as morally right, resulting in a perceived violation of one's core values and duties. There has been a growing interest in the prevalence of moral distress in healthcare, particularly as a root cause of burnout. A recent national survey on moral distress in radiology found that 98% of respondents experienced at least some degree of moral distress with 18% of respondents having left a position due to moral distress. One of the scenarios associated with the highest degree of moral distress related to the conflict that arises when one feels unable to fulfill teaching responsibilities due to high clinical demands. Now more than ever, clinician-educators are asked to do more with less time, fewer resources, and in an increasingly demanding work environment that is often discordant with providing quality education to their learners. In this manuscript, we aim to discuss the factors contributing to moral distress in radiologist clinician-educators as a framework to better understand the implications of these drivers, and to offer our perspective on potential mitigating measures.

Ensuring a Smooth Transition for Trainees Returning from Parental Leave - A Guide for Program Directors.

Transitioning from parental leave during radiology residency training can be a time of stress and uncertainty. However, there are ways that program directors can help make the transition smoother and less overwhelming. Trainees report numerous stressors upon returning from leave involving childcare, lactation concerns and logistics, and discrimination. Program directors can help alleveate these stressors by counseling trainees returning from parental leave and providing reseources and a supportive enviroment. This article provides a structured frame work with tool for programs directors to ensure the transition from parental leave back to training is a smooth one.

Self-Care and Storytelling for Radiologists: A Feasibility Study.

RATIONALE AND OBJECTIVES: Physician wellness and burnout mitigation strategies have become priority practices in recent years. Despite these efforts, however, physicians living with the psychological effects of the current COVID-19 global pandemic, political stressors, and social injustices, face ever increasing threats to their personal and professional well-being. This manuscript investigates the process of storytelling as a self-care practice for radiologists. MATERIALS AND METHODS: The AUR Well Being Ad-Hoc Committee introduced and approved Storytelling Geek Week, a virtual workshop held by The Moth, a Peabody award-winning storytelling nonprofit group. Nineteen AUR members applied and were selected for participation in the workshop which occurred over 5 days in November 2020. Anonymous electronic surveys were sent to participants before and after the workshop to gather feedback on their experience. RESULTS: Of the 19 AUR member participants, 12 (63%) completed the pre-workshop survey and 8 (42%) completed the post-workshop survey. Participant current state of well-being was found to be increased between the pre- and post-course surveys, with a statistically significant adjusted P-value of 0.017. All 8 post-workshop respondents reported that they would recommend the workshop to others. With regard to how participation in the workshop impacted their wellbeing, representative free text responses include, "helped with processing emotions," and "felt more connected to strangers." Regarding shifts in perspective as a result of workshop participation, representative free text responses include, "more empathetic" and "started focusing on hope and gratitude rather than sadness and anxiety." CONCLUSION: Participants in a storytelling workshop reported a positive impact on their perceived sense of well-being. Respondents also reports shifts in their sense of empathy and connectedness to others. This type of intervention may help to mitigate burnout and build community during challenging times.

Affecting Change: Enhancing Feedback Interactions with Radiology Trainees.

Feedback is a critical part of the learning process and is a valuable tool to empower adult learners. Modern feedback theory places the learner at the center of the feedback encounter. Individual and institutional barriers to effective giving and receiving of feedback can be overcome through education and attention to the form and content of feedback. We review the elements of effective feedback and address issues of framing, environmental, and social factors which aid in providing psychological safety and trust, as necessary elements to create a culture of feedback in radiology training programs. We provide practical strategies to empower learners with the necessary skills to solicit, receive, and reflect on feedback.

A Rare Presentation of Primary Cutaneous Low-Grade Neuroendocrine Tumor of the External Auditory Canal.

OBJECTIVE: To describe the first case of a primary cutaneous low-grade neuroendocrine tumor (cLGNET) originating from the external auditory canal as well as our team's surgical management. PATIENT: A healthy 34-year-old female presented with a low-grade neuroendocrine tumor of her right external auditory canal (EAC) which extended from the posterior-superior aspect of the EAC into the middle ear. INTERVENTION: A complete otological examination was performed in addition to CT and MRI imaging. The low-grade neuroendocrine tumor was surgically biopsied and further surgery was recommended for complete resection. RESULTS: Audiogram revealed profound right sensorineural hearing loss. CT scan demonstrated complete opacification of the right EAC, middle ear, and mastoid air cells, dystrophic calcification in the mesotympanum overlying the cochlear promontory, and no associated osseous erosion. MRI revealed abnormal FLAIR hyperintensity and enhancement of the labyrinthine segment of the right facial nerve, cochlea, and horizontal and posterior semicircular canals. An enhancing mass opacifying the right EAC demonstrating restricted diffusion on diffusion-weighted image was also evident. Pathologic examination and immunohistochemical staining confirmed a diagnosis of primary cLGNET of the EAC. CONCLUSION: Primary cLGNETs of the external ear are exceedingly rare but should be considered if an adult patient presents with a mass in the EAC. Management should include early biopsy and surgical excision followed by histological and immunohistochemical confirmation.

The Radiology Virtual Reading Room: During and Beyond the COVID-19 Pandemic.

The COVID-19 pandemic has disrupted the radiology reading room with a potentially lasting impact. This disruption could introduce the risk of obviating the need for the reading room, which would be detrimental to many of the roles of radiology that occur in and around the reading room. This disruption could also create the opportunity for accelerated evolution of the reading room to meet the strategic needs of radiology and health care through thoughtful re-design of the virtual reading room. In this article, we overview the impact of the COVID-19 pandemic on radiology in our institution and across the country, specifically on the dynamics of the radiology reading room. We introduce the concept of the virtual reading room, which is a redesigned alternative to the physical reading room that can serve the diverse needs of radiology and healthcare during and beyond the pandemic.

Radiologic anatomy of the round window relevant to cochlear implantation and inner ear drug delivery.

OBJECTIVE: To determine anatomic relationships and variation of the round window membrane to bony surgical landmarks on computed tomography. STUDY DESIGN: Retrospective imaging review. METHODS: 100 temporal bone images were evaluated. Direct measurements were obtained for membrane position. Vector distances and angulation from umbo and bony annulus were calculated from image viewer software coordinates. RESULTS: The angle of round window membrane at junction with cochlear basal turn was (42.1 ± 8.6)°. The membrane's position relative to plane of the facial nerve through facial recess was (14.7 ± 5.2)° posterior from a reference line drawn through facial recess to carotid canal. Regarding transtympanic drug delivery, the round window membrane was directed 4.1 mm superiorly from the inferior annulus and 5.4 mm anteriorly from the posterior annulus. The round window membrane on average was angled superiorly from the inferior annulus (77.1 ± 27.9)° and slightly anteriorly from the posterior annulus (19.1 ± 11.1°). The mean distance of round window membrane from umbo was 4 mm and posteriorly rotated 30° clockwise from a perpendicular drawn from umbo to inferior annulus towards posterior annulus. Together, these measurements approximate the round window membrane in the tympanic membrane's posteroinferior quadrant. CONCLUSIONS: These radiologic measurements demonstrate normal variations seen in round window anatomy relative to facial recess approach and bony tympanic annulus, providing a baseline to assess round window insertion for cochlear implantation and outlines anatomic factors affecting transtympanic drug delivery.

Neurosarcoidosis Directly Involving the Cervical Vagus Nerve.

OBJECTIVES: To present a novel location in which neurosarcoidomatous inflammation is identified and its accompanying presentation. METHODS: The authors present a case of bilateral vocal fold paresis associated with non-caseating granulomatous inflammation of the cervical and intra-axial portions of the vagus nerve masquerading as a cranial nerve tumor. RESULTS: Examination revealed bilateral vocal fold paresis and asymmetric palate elevation. MRI demonstrated enhancing bilateral jugular foramen masses, and neck ultrasound demonstrated bilateral thickened appearance of the vagus nerves. Vagus nerve biopsy demonstrated non-caseating granulomas. CONCLUSIONS: Neurosarcoidosis may contribute to variable cranial neuropathies. Vocal fold paresis is usually thought to arise from mediastinal compression of the left recurrent laryngeal nerve. Rarely, though, lesions may arise in other parts of the vagus nerve. Failure of response to steroids does not rule out the diagnosis, making tissue diagnosis important in some cases.

USMLE Step 3 Scores Have Value in Predicting ABR Core Examination Outcome and Performance: A Multi-institutional Study.

RATIONALE AND OBJECTIVES: We analyzed multi-institutional data to determine if Step 3 performance tiers can identify radiology residents with increased risk of Core examination failure and submean performance. MATERIALS AND METHODS: We collected Step 3 scores (USMLE Step 3 or COMLEX Level 3) and American Board of Radiology (ABR) Core examination outcomes and scores for anonymized residents from 13 different Diagnostic Radiology residency programs taking the ABR Core examination between 2013 and 2019. Step 3 scores were converted to percentiles based on Z-score, with Core outcome and performance analyzed for Step 3 groups based on 50th percentile and based on quintiles. Core outcome was scored as fail when conditionally passed or failed. Core performance was measured by the percent of residents with scores below the mean. Differences between Step 3 groups for Core outcome and Core performance were statistically evaluated. RESULTS: Data were available for 342 residents. The Core examination failure rate for 121 residents with Step 3 scores <50th percentile was 19.8% (fail relative risk = 2.26), significantly higher than the 2.7% failure rate for the 221 other residents. Of 42 residents with Step 3 scores in the lowest quintile, the Core failure rate increased to 31.0% (fail relative risk = 3.52). Core performance improved with higher Step 3 quintiles. CONCLUSION: Step 3 licensing scores have value in predicting radiology resident performance on the ABR Core examination, enabling residency programs to target higher risk residents for early assessment and intervention.

The Relationship Between ACR Diagnostic Radiology In-Training Examination Scores and ABR Core Examination Outcome and Performance: A Multi-Institutional Study.

PURPOSE: We analyzed multi-institutional data to understand the relationship of ACR Diagnostic Radiology In-Training Examination (DXIT) scores to ABR Core examination performance. METHODS: We collected DXIT rank scores and ABR Core examination outcomes and scores for anonymized residents from 12 different diagnostic radiology residency programs taking the ABR Core examination between 2013 and 2019. DXIT scores were grouped into quintiles based on rank score for residency year 1 (R1), residency year 2 (R2), and residency year 3 (R3) residents. Core outcome was scored as fail when conditionally passed or failed. Core performance was grouped using SD from the mean and measured by the percent of residents with scores below the mean. Differences between DXIT score quintiles for Core outcome and Core performance were statistically evaluated. RESULTS: DXIT and Core outcome data were available for 446 residents. The Core examination failure rate for the lowest quintile R1, R2, and R3 DXIT scores was 20.3%, 34.2%, and 38.0%, respectively. Core performance improved with higher R3 DXIT quintiles. Only 2 of 229 residents with R3 DXIT score ≥ 50th percentile failed the Core examination, with both failing residents having R2 DXIT scores in the lowest quintile. CONCLUSIONS: DXIT scores are useful evaluation metrics to identify a subgroup of residents at significantly higher risk for Core examination failure and another subgroup of residents at significantly lower risk for Core examination failure, with increasing predictive power with advancing residency year. These scores enable identification of approximately one-half of R3 residents whose risk of Core examination failure is negligible.

COVID-19 Impact on Well-Being and Education in Radiology Residencies: A Survey of the Association of Program Directors in Radiology.

RATIONALE AND OBJECTIVES: The COVID-19 pandemic has forced rapid evolution of the healthcare environment. Efforts to mitigate the spread of the virus through social distancing and shelter-at-home edicts have unintended consequences upon clinical and educational missions and mental well-being of radiology departments. We sought to understand the impact of the COVID-19 pandemic on radiology residencies with respect to the educational mission and perceptions of impact on well-being. MATERIALS AND METHODS: This study was IRB exempt. An anonymous 22 question survey regarding the impact of COVID-19 pandemic on educational and clinical missions of residencies, its perceived impact upon morale of radiologists and trainees and a query of innovative solutions devised in response, was emailed to the Association of Program Directors in Radiology membership. Survey data were collected using SurveyMonkey (San Mateo, California). RESULTS: Respondents felt the COVID-19 pandemic has negatively impacted their residency programs. Regarding the educational mission impact, 70.1% (75/107) report moderate/marked negative impact and 2.8% (3/107) that educational activities have ceased. Regarding the pandemic's impact on resident morale, 44.8% (48/107) perceive moderate/marked negative effect; perceived resident morale in programs with redeployment is significantly worse with 57.1% (12/21) reporting moderate/marked decrease. Respondents overwhelmingly report adequate resident access to mental health resources during the acute phase of the pandemic (88.8%, 95/107). Regarding morale of program directors, 61% (65/106) report either mild or marked decreased morale. Program innovations reported by program directors were catalogued and shared. CONCLUSION: The COVID-19 pandemic has markedly impacted the perceived well-being and educational missions of radiology residency programs across the United States.

The Relationship Between US Medical Licensing Examination Step Scores and ABR Core Examination Outcome and Performance: A Multi-institutional Study.

PURPOSE: We analyzed multi-institutional data to understand the relationship of US Medical Licensing Examination (USMLE) Step scores to ABR Core examination performance to identify Step score tiers that stratify radiology residents into different Core performance groups. METHODS: We collected USMLE Step scores and ABR Core examination outcomes and scores for anonymized residents from 13 different diagnostic radiology residency programs taking the ABR Core examination between 2013 and 2019. USMLE scores were grouped into noniles using z scores and then aggregated into three tiers based on similar Core examination pass-or-fail outcomes. Core performance was grouped using standard deviation from the mean and then measured by the percent of residents with scores below the mean. Differences between Step tiers for Core outcome and Core performance were statistically evaluated (P < .05 considered significant). RESULTS: Differences in Step 1 terciles Core failure rates (45.9%, 11.9%, and 3.0%, from lowest to highest Step tiers; n = 416) and below-mean Core performance (83.8%, 54.1%, and 21.1%, respectively; n = 402) were significant. Differences in Step 2 groups Core failure rates (30.0%, 10.6%, and 2.0%, from lowest to highest Step tiers; n = 387) and below-mean Core performance (80.0%, 43.7%, and 14.0%, respectively; n = 380) were significant. Step 2 results modified Core outcome and performance predictions for residents in Step 1 terciles of varying statistical significance. CONCLUSIONS: Tiered scoring of USMLE Step results has value in predicting radiology resident performance on the ABR Core examination; effective stratification of radiology resident applicants can be done without reporting numerical Step scores.
