ABSTRACT

OBJECTIVES: This study is an evaluation of the emergency department (ED) satisfaction with the current radiologic reporting system used at a major Northeastern academic medical center. The radiology reports are the main form of communication and usually the final product of any radiological investigation delivered to clinicians. The aim of this study was to improve current radiology reporting practices and to better tailor reports to match the needs and expectations of ED clinicians. METHODS: A 9-question online survey was sent to ED residents, fellows, faculty, and nurse practitioners/advanced practice providers at a major Northeastern academic medical center in the United States. For the open-ended section, coding and emergent theme categorization was conducted for quantification of responses. The survey was designed to evaluate the attitudes toward the structure, style, form, and wording used in reports. RESULTS: The response rate was 48.6% (68/140). The ED respondents were generally satisfied with radiology reports, their language, vocabulary, and clarity. They preferred the impression section to be before the findings in simple examinations and to stratify the reports according to emergency status for complex examinations. They did not like extended differential, hedge terms, and delayed reporting. Additionally, ED respondents recommended focused, fast reporting with considerable changes toward a more standardized report. CONCLUSIONS: This evaluation delivered a list of actionable recommendations. The top recommendation is to standardize reporting structure, style, and lexicon, in addition to being focused, timely, and brief.

ABSTRACT

PURPOSE: An integral part of realizing the enormous potential of imaging in patient care is close communication between radiologists and referring physicians. One key element of this process is the communication of unexpected significant findings. The authors examined the performance of a PACS-based alert system in the appropriate communication of reports containing unexpected significant findings to referring physicians. METHODS: A PACS-integrated key word system was developed such that an e-mail was sent to the referring clinician if a radiologist detected a significant unexpected finding. The number, source, and outcome of chest radiographic unexpected findings over a 14-month period were analyzed. The time for response of the referring physician plus time for follow-up were also examined. RESULTS: Key words were applied to 158 of the 39,665 chest radiographs (0.4%) obtained during the study period. The emergency department was the most frequent referral location (46.2%). Final diagnostic categories included malignancy (13.9%), benign lesion (49.4%), and no abnormality (20.2%). The average time to acknowledgment by clinicians of notification was 3.1 days, although 57.6% were acknowledged within 24 hours. The mean time interval to the next relevant radiologic investigation was 26 days among the 77.8% of findings that underwent radiologic follow-up. CONCLUSIONS: The development of electronic alert systems, which are integrated into PACS, can aid greatly in report communication and eliminate the risk associated with unread reports that contain significant or unexpected findings.

ABSTRACT

OBJECTIVE: Iterative reconstruction (IR) allows diagnostic CT imaging with less radiation exposure than filtered back projection (FBP). We studied an IR low-dose CT abdomen/pelvis (LDCTAP) protocol, designed to image at an effective dose (ED) approximating 1 mSv in patients with Crohn's disease (CD). METHODS: Forty patients, mean age 37 ± 13.4 years (range 17-69), with CD underwent two synchronous CT protocols (conventional-dose (CDCTAP) and LDCTAP). CDCTAP and LDCTAP images were compared for diagnostic acceptability, yield, image quality and ED (in millisieverts). The optimal level of IR for LDCTAP was also studied. RESULTS: LDCTAP yielded a mean ED of 1.3 ± 0.8 mSv compared with 4.7 ± 2.9 mSv for CDCTAP, reducing ED by 73.7 ± 3.3 % (mean dose reduction, 3.5 ± 2.1 mSv; P < 0.001) and dose length product by 73.6 ± 2.6 % (P < 0.001). Sub-millisievert (0.84 mSv) imaging was performed for patients with a body mass index (BMI) less than 25 (i.e. 63 % of our cohort). LDCTAP resulted in increased image noise and reduced diagnostic acceptability compared with CDCTAP despite use of IR, but detection of extra-luminal complications was comparable. CONCLUSION: Patients with suspected active CD can be adequately imaged using LDCTAP, yielding comparable information regarding extent, activity and complications of CD compared with CDCTAP, but with 74 % less dose. LDCTAP at doses equivalent to that of two abdominal radiographs represents a feasible alternative to CDCTAP. KEY POINTS: • Radiation dose is a concern when imaging patients with Crohn's disease. • New techniques allow low-dose abdominopelvic CT with acceptable image quality. • Using hybrid iterative reconstruction, its diagnostic yield compares well with that of conventional CT. • Sub-millisievert CT of patients with Crohn's disease appears technically and clinically feasible.

ABSTRACT

Interventional Radiology (IR) is occupying an increasingly prominent role in the care of patients with cancer, with involvement from initial diagnosis, right through to minimally invasive treatment of the malignancy and its complications. Adequate diagnostic samples can be obtained under image guidance by percutaneous biopsy and needle aspiration in an accurate and minimally invasive manner. IR techniques may be used to place central venous access devices with well-established safety and efficacy. Therapeutic applications of IR in the oncology patient include local tumour treatments such as transarterial chemo-embolisation and radiofrequency ablation, as well as management of complications of malignancy such as pain, organ obstruction, and venous thrombosis.

ABSTRACT

OBJECTIVES: This study assessed students' awareness of radiation exposures and determined the impact a curriculum in clinical radiology (CICR) had on awareness. METHODS: Six hundred seventy medical students at one medical school were studied. CICR was delivered in yearly modules over the 5-year programme. Five hundred twenty-three students (years 1-5), exposed to increasing numbers of CICR modules and 147 students beginning medical school (year 0), represented the study and control groups, respectively. Students completed a multiple choice questionnaire assessing radiation knowledge and radiology teaching. RESULTS: Most students in the study population received CICR but 87% considered they had not received radiation protection instruction. The percentage of correctly answered questions was significantly higher in the study population than the control group (59.7% versus 38%, p < 0.001). Students who received CICR achieved higher scores than those who did not (61.3% compared with 42.8%, p < 0.001). Increasing exposure to CICR with each year of medical education was associated with improved performance. CONCLUSIONS: Assessment of students' awareness of radiation exposures in diagnostic imaging demonstrates improved performance with increasing years in medical school and/or increasing exposure to CICR. Findings support the Euroatom 97 directive position, advocating implementation of radiation protection instruction into the undergraduate medical curriculum.

ABSTRACT

OBJECTIVE: To evaluate the use of emergent dynamic intravenous contrast-enhanced computed tomography (CT) in the diagnosis of active arterial extravasation in patients admitted to hospital after blunt abdominal trauma. METHODS: Four-hundred and ninety-eight consecutive emergent contrast-enhanced computed tomographic images of the abdomen and pelvis were retrospectively reviewed. The presence of and site(s) of active arterial extravasation were recorded. Two radiologists reviewed the images and compared the site(s) of extravasated arterial contrast agent with the site(s) of active hemorrhage established at angiography (n = 9) or surgery (n = 4). RESULTS: Twenty-eight patients' computed tomographic images were identified as showing signs of extravasation of contrast agent representing active arterial bleeding. A total of 49 sources of active arterial extravasation were identified, 37 in 19 patients. A pelvic source of active arterial hemorrhage was most frequent and was typically associated with unstable pelvic fractures (n = 18). Other sources of active arterial hemorrhage included the liver (n = 3), spleen (n = 2), retroperitoneum (n = 1), kidney (n = 1), mesentery (n = 1), abdominal wall (n = 3) and lumbar region (n = 1). Only 9 of 28 patients became sufficiently hemodynamically unstable to warrant angiography. All 9 patients had a pelvic source of arterial extravasation on contrast-enhanced CT, and 7 demonstrated active bleeding requiring embolization. The contrast-enhanced computed tomographic images correctly indicated the anatomical source of bleeding in all 7 cases. CONCLUSION: In patients who have experienced blunt abdominal trauma, attention should be paid to the computed tomographic features of active arterial hemorrhage. In our series, the pelvis was the most common source of active arterial bleeding, which was typically associated with unstable pelvic fractures.

ABSTRACT

We retrospectively reviewed the computed tomographic (CT) examinations of 15 cases of abdominal wall hernia due to abdominal trauma; 13 patients had been injured in motor vehicle accidents (11 of those were belted in). All hernias were correctly identified on CT and confirmed intraoperatively. Traumatic abdominal wall hernia proved an important indicator of associated visceral injury, especially to the bowel (n = 6) and mesentery (n = 10). Careful review of the bowel and mesentery should thus be undertaken when disruption of the abdominal wall is documented. Radiologists should be aware, however, that CT findings may correlate poorly with severity of injury in these areas. In these instances, close clinical correlation and, sometimes, rescanning may be necessary.
