A comparison of sagittal MRI and lateral radiography in determining the Insall-Salvati ratio and diagnosing patella alta in the pediatric knee.

BACKGROUND: The Insall-Salvati ratio is a technique for determining patellar height that relies on bony landmarks. Magnetic resonance imaging (MRI) and plain radiography are used interchangeably to assess the Insall-Salvati ratio in the pediatric population despite the lack of validity in the literature. OBJECTIVE: The purpose of this study was to investigate if the Insall-Salvati ratio and patella alta as determined on MRI are comparable to those determined on radiography in pediatric patients. MATERIALS AND METHODS: We conducted a retrospective review of 49 pediatric patients (age range: 7.5-17.0 years) with unfused growth plates who underwent both knee MRI and lateral knee radiography. Measurements for calculating the Insall-Salvati ratio (the ratio of patella tendon length to patella length) were obtained by three observers. Data were analyzed using paired t-tests and Pearson's correlation. A reliability assessment and inter-method agreements were performed. Patella alta was defined as an Insall-Salvati ratio > 1.2. Additional cutoffs of Insall-Salvati ratios > 1.3 and > 1.4 were also analyzed. RESULTS: There was no statistically significant difference between Insall-Salvati ratio as determined on MRI (mean: 1.20) and radiographs (mean: 1.25; P > 0.05). There was a strong correlation between Insall-Salvati ratio as determined on MRI and radiographs (Pearson's r = 0.6) with moderate consistency (Cronbach's alpha = 0.78). There was a good level of agreement between the diagnosis of patella alta on MRI and radiographs when defined as an Insall-Salvati ratio greater than 1.2 and 1.3 (Cohen's kappa = 0.61). CONCLUSION: The results demonstrate a strong association between Insall-Salvati ratio and patella alta derived from MRI and radiographs in children ages 7.5 years and older.

Resident Physicians' Perceptions of Diagnostic Radiology and the Declining Interest in the Specialty.

RATIONALE AND OBJECTIVES: The relative competitiveness of radiology and the number of first-choice applicants to diagnostic radiology have steadily declined over the past decade. The purpose of this study was to identify factors contributing to the declining interest in diagnostic radiology as a career and to explore factors affecting specialty choice. MATERIALS AND METHODS: A retrospective survey was distributed to resident physicians at a single academic center between July and August 2017. Participants identified factors affecting career choice and evaluated level of agreement with statements regarding radiology using 5-point Likert scales. Higher scores indicated stronger agreement. RESULTS: One hundred and fifty-two resident physicians from Canada participated (21.5% response rate): 20 radiology and 132 nonradiology. Of the total, 27% were registered in postgraduate year (PGY) 1, 23% in PGY 2, 15% in PGY 3, 19% in PGY 4, and 16% in PGY 5, or above. Sixty-one percent of the respondents self-reported as female, 34% as male, and 5% as other/unknown. Of those in radiology, 40% self-reported as female, 55% as male, and 5% as other/unknown, compared to 64% female, 31% male, and 5% other/unknown in other specialties. Regardless of specialty, positive clinical/mentoring experiences strongly affected career choice. Radiology residents were attracted to diverse pathology (M = 4.5) and positive staff/resident interactions (M = 4.4). Nonradiology residents were deterred by lack of patient contact (M = 3.9) and dark work environment (M = 3.6). Resident physicians who had applied to radiology were more likely to report positive mentorship during medical school, disagree that technology will replace radiologists, and desire a higher income specialty (Wald = 56.6, p < 0.001). More recent graduates showed a higher level of concern regarding the potential negative impact of technology and outsourcing on the profession (F (3, 189) = 2.6, p = 0.05). Several trainees (21%) considered radiology, but lacked mentorship (52%) and identified job market concerns (29%). CONCLUSION: More recent graduates are relatively more concerned about technology replacing radiologists, and radiology applicants have less concern about artificial intelligence replacing radiologists. As positive interactions with radiologists and mentorship are key influencers, our results advocate for early training exposure and reinforcement regarding the positive outlook of the profession.

Subspecialty Employment Needs in Academic Radiology Settings Across Canada.

PURPOSE: The purpose of this survey was to identify current and projected subspecialty employment needs across Canadian academic radiology practices. METHODS: An electronic survey was distributed to academic radiology department heads within the faculties of medicine at Canadian universities between September and October 2019. Respondents identified the number of partnership track radiologists hired in the last academic year, the number of fellowship-trained new hires, and the top 3 subspecialties for new and prospective hires. Descriptive statistics were used to summarize the data. RESULTS: Nine academic radiology department heads responded to the survey (75% response rate) with good regional representation across Canada. Ninety-five percent of new hires within the last academic year were subspecialty fellowship trained. The top subspecialties for new hires in the last year were abdominal imaging and interventional neuroradiology, with 77.8% and 44.4% of academic leaders reporting them as one of the top 3 subspecialties, respectively. The top 3 subspecialties for prospective hires in the next academic year included musculoskeletal imaging (n = 6, 66.7%), followed by abdominal imaging (n = 5, 55.6%), with pediatric radiology (n = 3, 33.3%) and cardiothoracic imaging (n = 3, 33.3%) tying for third place. There was some variability in the subspecialty needs for hires between regions. CONCLUSIONS: The survey results provide valuable information about the current and future subspecialty needs of academic radiology practices. The data obtained can provide guidance to trainees regarding fellowship training options that will optimize their future employability.

Cross-sectional pictorial review of IgG4-related disease.

Immunoglobulin G4-related disease (IgG4-RD) is an autoimmune disorder characterized by the infiltration of one or more organs with IgG4-positive plasma cells resulting in inflammatory lesions and fibrosis. Although the pancreas is the most commonly affected organ, involvement of extrapancreatic organs is an increasingly recognized manifestation of the disease. Patients may be asymptomatic and serum IgG4 concentrations may be elevated or normal. Treatment consists of glucocorticosteroid treatment, with excellent response. A definitive diagnosis requires histopathology with imaging playing a key role in avoiding treatment delays. This pictorial review will focus on the most current knowledge regarding IgG4-RD including its common and less common manifestations and the roles of multidetector CT, MRI and ultrasound in the diagnosis and management of suspected IgG4-RD. Knowledge of the varied imaging findings of this multi systemic disease is essential for radiologists to avoid misdiagnosis and assist with timely and effective treatment.

Is There an Association between STARD Statement Adherence and Citation Rate?

Purpose To determine if adherence to the Standards for Reporting of Diagnostic Accuracy (STARD) is associated with postpublication citation rates. Materials and Methods A comprehensive search of PubMed, EMBASE, and Cochrane Library databases was performed to identify published articles that have evaluated adherence of diagnostic accuracy studies to the STARD statement. These were included if the number of STARD items reported ("STARD result") could be obtained for each evaluated study. The date of publication, journal impact factor, and citation rate (citations per day) were extracted for the diagnostic accuracy studies. Univariate correlations were performed to identify any association between STARD result, impact factor, and citation rate. Multivariate regression analysis was performed to explore the effect of impact factor on postpublication citation rates. Results The authors were able to obtain the STARD results for 1002 "original" diagnostic accuracy studies from eight different "STARD evaluation" articles. The median impact factor was 3.97 (interquartile range [IQR]: 2.32-6.21), the median STARD result was 15 of 25 items (IQR: 12-18), and the median citation rate was 0.007 citations per day (IQR: 0.0032-0.017). The authors identified a weak positive correlation between STARD result and citation rate (r = 0.096; 95% confidence interval [CI]: 0.034, 0.157), a moderate positive correlation between impact factor and citation rate (r = 0.58; 95% CI: 0.535, 0.617), and a weak positive correlation between impact factor and STARD result (r = 0.13; 95% CI: 0.064, 0.186). Multivariate analysis accounting for journal clustering effects revealed that, when impact factor is partialed out, the positive correlation between citation rate and STARD result does not persist (r = 0.029; 95% CI: -0.033, 0.091). Conclusion There is a positive correlation between completeness of reporting, as evaluated with STARD, and citation rate as well as impact factor. When adjusted for impact factor, the positive correlation between completeness of reporting and citation rate does not persist.

Wearing my heart on my chest: dating, new relationships, and the reconfiguration of self-esteem after breast cancer.

OBJECTIVE: This study investigated women's experiences of establishing an intimate relationship with a new partner after breast cancer diagnosis and treatment. METHODS: Fifteen breast cancer survivors, who were either actively dating or in a new intimate relationship that began post-diagnosis, participated in semi-structured interviews. Interview transcripts were analyzed using the grounded theory method. RESULTS: The analysis yielded Wearing My Heart on My Chest as the core category with three underlying categories: (1) Losing and Regaining Self and Bodily Esteem; (2) Taking the Leap: Dating and the Obligation to Disclose; and (3) Reclaiming of Self through the New Relationship. The categories refer to the experience of profound vulnerability invoked by the history of breast cancer and the act of verbally and physically revealing this past to a new intimate partner. Disclosure entailed a series of successive 'tests' of the new partner for his ability to accept the physical and psychological ramifications of breast cancer, with the resulting relationship becoming a vehicle through which women regained self-esteem. CONCLUSIONS: The process of dating and starting a new intimate relationship had the potential to restore women's self and bodily esteem previously diminished by breast cancer. The reconfiguration of self-esteem following breast cancer is thus experienced as an ongoing process that begins with diagnosis and continues well into the new relationship.
