Assessment of Radiology Training During Radiation Oncology Residency.

A strong foundation in diagnostic imaging is essential to the practice of radiation oncology. This study evaluated radiology training in radiation oncology residency. An online survey was distributed to current radiation oncology residents in the USA by e-mail in 2017. Responses were summarized using frequency and percentages and compared with chi-square test and Spearman's rank correlation when appropriate. One hundred five residents completed the survey. Although most residents felt that a strong knowledge base in diagnostic radiology was moderately or extremely important (87%, n = 90/104), the majority were only somewhat confident in their radiology skills (61%, n = 63/104) and were only somewhat, minimally, or not at all satisfied with their training (79%, n = 81/103). Although there was an association between increasing post-graduate training and confidence level (p = 0.01062, ρ = 0.24959), the majority of graduating residents feel only somewhat confident in radiology skills (63%, n = 12/19). Residents were most commonly exposed to radiology via multidisciplinary conferences (96%, n = 100/104), though only 15% (n = 16/104) of residents ranked these as the most beneficial component of their radiology training and 13% (n = 13/101) of residents felt these were the least beneficial. Most residents (60%, n = 63/105) believe there is a need for dedicated radiology training during residency, preferring monthly formal didactics (68%, n = 71/105) co-taught by a radiologist and radiation oncologist (58%, n = 61/105). Radiation oncology residents feel their radiology training is suboptimal, suggesting a need for more guidance and standardization of radiology curriculum. A preferred option may be monthly didactics co-taught by radiologists and radiation oncologists; however, future studies should assess the effectiveness of this model.

Don't Forget the Abdominal Wall: Imaging Spectrum of Abdominal Wall Injuries after Nonpenetrating Trauma.

Abdominal wall injuries occur in nearly one of 10 patients coming to the emergency department after nonpenetrating trauma. Injuries range from minor, such as abdominal wall contusion, to severe, such as abdominal wall rupture with evisceration of abdominal contents. Examples of specific injuries that can be detected at cross-sectional imaging include abdominal muscle strain, tear, or hematoma, including rectus sheath hematoma (RSH); traumatic abdominal wall hernia (TAWH); and Morel-Lavallée lesion (MLL) (closed degloving injury). These injuries are often overlooked clinically because of (a) a lack of findings at physical examination or (b) distraction by more-severe associated injuries. However, these injuries are important to detect because they are highly associated with potentially grave visceral and vascular injuries, such as aortic injury, and because their detection can lead to the diagnosis of these more clinically important grave traumatic injuries. Failure to make a timely diagnosis can result in delayed complications, such as bowel hernia with potential for obstruction or strangulation, or misdiagnosis of an abdominal wall neoplasm. Groin injuries, such as athletic pubalgia, and inferior costochondral injuries should also be considered in patients with abdominal pain after nonpenetrating trauma, because these conditions may manifest with referred abdominal pain and are often included within the field of view at cross-sectional abdominal imaging. Radiologists must recognize and report acute abdominal wall injuries and their associated intra-abdominal pathologic conditions to allow appropriate and timely treatment. © RSNA, 2017.

Anorectal Cancer: Critical Anatomic and Staging Distinctions That Affect Use of Radiation Therapy.

Although rectal and anal cancers are anatomically close, they are distinct entities with different histologic features, risk factors, staging systems, and treatment pathways. Imaging is at the core of initial clinical staging of these cancers and most commonly includes magnetic resonance imaging for local-regional staging and computed tomography for evaluation of metastatic disease. The details of the primary tumor and involvement of regional lymph nodes are crucial in determining if and how radiation therapy should be used in treatment of these cancers. Unfortunately, available imaging modalities have been shown to have imperfect accuracy for identification of nodal metastases and imaging features other than size. Staging of nonmetastatic rectal cancers is dependent on the depth of invasion (T stage) and the number of involved regional lymph nodes (N stage). Staging of nonmetastatic anal cancers is determined according to the size of the primary mass and the combination of regional nodal sites involved; the number of positive nodes at each site is not a consideration for staging. Patients with T3 rectal tumors and/or involvement of perirectal, mesenteric, and internal iliac lymph nodes receive radiation therapy. Almost all anal cancers warrant use of radiation therapy, but the extent and dose of the radiation fields is altered on the basis of both the size of the primary lesion and the presence and extent of nodal involvement. The radiologist must recognize and report these critical anatomic and staging distinctions, which affect use of radiation therapy in patients with anal and rectal cancers.

Concordance of MRI With Pathology for Primary Staging of Rectal Cancer in Routine Clinical Practice: A Single Institution Experience.

PURPOSE: MRI is the preferred imaging modality for primary staging of rectal cancer, used to guide treatment. Patients identified with clinical stage I disease receive upfront surgical resection; those with clinical stage II or greater undergo upfront neoadjuvant therapy. Although clinical under-/over-staging may have consequences for patients and presents opportunities for organ preservation, the correlation between clinical and pathologic staging in routine clinical practice within a single institute has not been fully established. METHODS: This retrospective, Institutional Review Board-approved study, conducted at a National Cancer Institute-Designated Comprehensive Cancer Center with a multi-disciplinary rectal cancer disease center, included patients undergoing rectal MRI for primary staging January 1, 2018-August 30, 2020. Data collection included patient demographics, initial clinical stage via MRI report, pathologic diagnosis, pathologic stage, and treatment. The primary outcome was concordance of overall clinical and pathologic staging. Secondary outcomes included reasons for mismatched staging. RESULTS: A total 105 rectal adenocarcinoma patients (64 males, mean age 57 ± 12.7 years) had staging MRI followed by surgical resection. A total of 28 patients (27%) had mismatched under-/over- staging. Ten patients (10%) were understaged with mismatched T stage group (clinical stage I, pathologic stage II), five (5%) were understaged with mismatched N stage group (clinical stage I, pathologic stage III), and 13 (12%) were overstaged (clinical stage II-III, pathologic stage 0-I). Treatment matched concordance between clinical and pathologic stages was 86%. CONCLUSION: MRI for primary rectal cancer staging has high concordance with pathology. Future studies to assess strategies for reducing clinically relevant understaging would be beneficial.

Development, Implementation, and Assessment of a Quality, Research, Education, and Wellness (QREW) Professional Development Lecture Series for Radiology Faculty.

RATIONALE AND OBJECTIVES: Professional development is important to academic radiologists. We developed, implemented, and assessed an internal professional development lecture series focusing on the non-interpretative themes of Quality, Research, Education, and Wellness (QREW). MATERIALS AND METHODS: The faculty of a 29-member abdominal radiology division at an academic hospital were invited to deliver 1-hour virtual lectures on noninterpretative topics to division colleagues. Topics were curated by division leadership based on the perceived needs of faculty. Anonymous feedback was collected from attendees for quality improvement purposes and analyzed using descriptive statistics and Fisher's exact test. RESULTS: Over 17 months, 13 QREW lectures were delivered. In total, 91 feedback forms were completed by faculty (mean 7 forms, range 2-12 per session). Of these, 57 responses (63%) were by those <7 years post training ("junior faculty"), 34 responses (37%) by those ≥ 7 years from training ("senior faculty"). Most respondents reported low levels of prior instruction (80/90, 89%) and personal knowledge (49/91, 54%) on topics. Compared to senior faculty, a greater proportion of junior faculty reported less prior instruction (73% vs 98%, P < 0.001) and less personal knowledge (32% vs 65%, P < 0.01). Most respondents agreed or strongly agreed that the topics were important to their clinical practice (87/90, 97%), professional development (86/90, 96%), and personal well-being (82/91, 90%). Faculty identified the QREW program as a major contributor to their professional development. CONCLUSION: A noninterpretative professional development lecture series delivered by radiology faculty in a virtual, interactive format is feasible and effective, particularly for junior faculty.

Study Smarter: Applying the Science of Learning to Radiology.

Lifelong learning is critical to a successful career in radiology, but many learners use inefficient or ineffective studying strategies developed from personal experience. Decades of cognitive psychology research have identified several techniques that consistently improve knowledge consolidation and retrieval. To improve their knowledge and ultimately patient care, radiologists should strive to understand and adopt these learning techniques. The first part of this article reviews several evidence-based learning principles, including active retrieval and the testing effect, spaced repetition, interleaving, deliberate practice, and growth mind-set. The second part provides practical suggestions on how to incorporate these principles into radiology learning, both during training and beyond.

A Team-Based Approach to Radiology Resident Case Conference to Improve Camaraderie Among Trainees.

INTRODUCTION: In light of increasing concerns regarding resident burnout, we developed a team-based approach (TBA) to radiology resident case conference to foster wellness by cultivating camaraderie and a positive learning environment. METHODS: Teaching faculty provided both a traditional hot-seat and a TBA format case conference. Resident perceptions of each conference format were assessed using a 16-item questionnaire, with 14 of the items utilizing a 7-point Likert scale to assess the learning environment, including measures related to wellness. A two-sided Wilcoxon rank-sum test was used to compare responses between the 2 formats of teaching conferences. RESULTS: Four paired teaching sessions were performed by 4 individual faculty. Sixty-six individual resident responses were received for the hot-seat and TBA conferences in aggregate. Residents responded "strongly agree" to positive statements more often for the TBA format compared with hot-seat for 13 out of the 14 items used to assess perceptions of the learning environment, including measures of wellness and camaraderie. The level of agreement on a 7-point Likert scale pertaining to the statement "The format of this case conference improves camaraderie among my co-residents" had a median value of 4.5 for the hot-seat format and 7 for the TBA format (P = 0.002). DISCUSSION: A TBA format for resident case conference may foster a sense of camaraderie among trainees. Residency programs may consider supplementing hot-seat conferences with the TBA method to address increasing burnout among trainees and promote resident wellbeing.

The Pre-Radiology Internship: Room for Improvement?

BACKGROUND: A clinical internship is currently required by the American Board of Radiology prior to Radiology residency. The purpose of this investigation is to evaluate practicing radiologists' perspectives on the value of the internship and their recommendations for optimization. METHODS: A five-minute online survey was distributed via email to practicing radiologist members of the American College of Radiology. RESULTS: A total of 566 completed responses (11.3% response rate) were received. Most respondents agreed that their internship was essential for improving non-radiology clinical knowledge (84%) and affirming their decision to become a radiologist (74%). Most respondents (59%) disagree that the one-year internship before residency should be eliminated. Most (53%) of the radiologists in an academic practice agreed that internship should be integrated into Radiology residency. If radiologists were to redesign the internship ("PreRad Internship"), a majority of the respondents would include training in other medical specialties (71%), working along technologists (55%) and informatics/AI/computer science (54%). While the greatest proportion (50%) of interventional radiologists reported a Surgery internship would be the most beneficial for their primary subspecialty (50%), diagnostic radiologists most commonly (27%) reported the PreRad Internship would be the most beneficial. The greatest proportions of Abdominal-, Breast-, and Neuroradiology-trained respondents reported a PreRad Internship would be the most beneficial internship for their primary field of subspecialty Radiology practice (32%, 36%, and 33%, respectively). CONCLUSION: The internship before Radiology residency offers some benefits but could be further optimized. There is support from practicing radiologists for a redesigned, more Radiology-specific PreRad Internship.

Think Like an MBA: Development, Implementation, and Evaluation of an Academic Radiology Business Series (ARBS) for Radiology Trainees.

RATIONALE AND OBJECTIVES: To address existing educational gaps in the business of radiology and medicine, we developed, implemented, and evaluated an Academic Radiology Business Series (ARBS) as part of a longitudinal noninterpretive skills curriculum in our radiology residency program. MATERIALS AND METHODS: Mixed lecture- and discussion-based sessions were prepared and taught by content experts and radiologist-leaders at our institution in the style of a typical MBA curriculum, drawing on five core pillars: strategy, management, operations, finance, and health policy and economics. The series concluded with an interactive discussion of a Harvard Business School case study. To study the effectiveness of the curriculum, Wilcoxon rank-sum test was used to compare survey results before and after the curriculum. RESULTS: Nearly 80% of the pre-curriculum survey respondents were not satisfied with the current training offered in the business of medicine. Although 94% of trainees were interested in pursuing leadership positions in healthcare, they have self-reported knowledge gaps in the fundamentals of the business of medicine. There were significant improvements in satisfaction with their training in the business of medicine and perceived improvements in knowledge of important concepts in the business of medicine after participating in the curriculum (p < 0.001). CONCLUSION: Radiology trainees have strong interest in the business of radiology and appreciate its importance yet feel inadequately prepared during training. Intentional training incorporated into residency education in the form of an innovative educational initiative that brings radiology trainees together and utilizes an institution's own leaders to teach is feasible and effective.

Stratification of cystic renal masses into benign and potentially malignant: applying machine learning to the bosniak classification.

PURPOSE: To create a CT texture-based machine learning algorithm that distinguishes benign from potentially malignant cystic renal masses as defined by the Bosniak Classification version 2019. METHODS: In this IRB-approved, HIPAA-compliant study, 4,454 adult patients underwent renal mass protocol CT or CT urography from January 2011 to June 2018. Of these, 257 cystic renal masses were included in the final study cohort. Each mass was independently classified using Bosniak version 2019 by three radiologists, resulting in 185 benign (Bosniak I or II) and 72 potentially malignant (Bosniak IIF, III or IV) masses. Six texture features: mean, standard deviation, mean of positive pixels, entropy, skewness, kurtosis were extracted using commercial software TexRAD (Feedback PLC, Cambridge, UK). Random forest (RF), logistic regression (LR), and support vector machine (SVM) machine learning algorithms were implemented to classify cystic renal masses into the two groups and tested with tenfold cross validations. RESULTS: Higher mean, standard deviation, mean of positive pixels, entropy, skewness were statistically associated with the potentially malignant group (P ≤ 0.0015 each). Sensitivity, specificity, positive predictive value, negative predictive value, and area under curve of RF model was 0.67, 0.91, 0.75, 0.88, 0.88; of LR model was 0.63, 0.93, 0.78, 0.86, 0.90, and of SVM model was 0.56, 0.91, 0.71, 0.84, 0.89, respectively. CONCLUSION: Three CT texture-based machine learning algorithms demonstrated high discriminatory capability in distinguishing benign from potentially malignant cystic renal masses as defined by the Bosniak Classification version 2019. If validated, CT texture-based machine learning algorithms may help reduce interreader variability when applying the Bosniak classification.

Rectal MRI after neoadjuvant chemoradiation therapy: a pictorial guide to interpretation.

Magnetic resonance imaging (MRI) is the current reference standard imaging modality for restaging rectal cancer after neoadjuvant chemoradiation and is used to guide clinical management decisions. This pictorial essay provides an illustrative atlas of the key MRI features used to assess rectal cancer after treatment. MRI findings of residual tumor including non-mucinous, mucinous, and signet-ring cell adenocarcinoma subtypes are correlated with histopathology. Imaging appearances of treatment changes that mimic residual tumor in the setting of confirmed pathological complete response at resection are illustrated. Treatment complications are also shown. Knowledge of these imaging findings and their importance may help radiologists comply with all elements of the structured reporting templates proposed by the Rectal Cancer Disease Focused Panel of the Society of Abdominal Radiology and by the European Society of Gastrointestinal and Abdominal Radiology.

Improving the completeness of structured MRI reports for rectal cancer staging.

PURPOSE: Assess the impact of a multifaceted intervention to improve the completeness of structured MRI reports for patients undergoing initial staging for rectal cancer. METHODS: This Institutional Review Board-approved retrospective study was performed at a large academic hospital. MRI reports for initial staging of rectal cancer in 2017 and 2019 were analyzed pre- and post-implementation of multiple quality improvement interventions in 2018, including harmonizing MRI protocols across the institution, educational conferences and modules, and requiring second opinion consultation for all MRI rectal cancer examinations. The primary outcome measure was the completeness of rectal cancer staging MRI reports, classified as optimal, satisfactory, or unsatisfactory based on the inclusion of 15 quality measures pre-defined by a consensus of abdominal and cancer imaging subspecialists, colorectal surgeons, and radiation oncologists at our institution, based on published recommendations. Fisher's exact test was used to evaluate changes in report quality and documentation of each quality measure. RESULTS: The study included 138 MRI reports, of which 72 (52%) were completed in 2017 pre-intervention. Post intervention, the proportion of optimal reports increased significantly from 52.8% (38/72) to 71.2% (47/66) (p = 0.035). Documentation of 1 quality measure (N stage) increased post intervention from 91.7% (66/72) to 100% (66/66) (p = 0.029). Documentation of 7 quality measures was 100% post intervention, with a documentation rate of > 95% for all quality measures except radial location of tumor. CONCLUSION: A combination of educational and system-wide interventions was associated with an improvement in the completeness of structured MRI reports for rectal cancer staging.

Beyond business as usual: Radiology residency educational response to the COVID-2019 pandemic.

The COVID-19 pandemic has disrupted standard hospital operations and diagnostic radiology resident education at academic medical centers across the country. Deferment of elective surgeries and procedures coupled with a shift of resources toward increased inpatient clinical needs for the care of COVID-19 patients has resulted in substantially decreased imaging examinations at many institutions. Additionally, both infection control and risk mitigation measures have resulted in minimal on-site staffing of both trainees and staff radiologists at many institutions. As a result, residents have been placed in nonstandard learning environments, including working from home, engaging in a virtual curriculum, and participating in training sessions in preparation for potential reassignment to other patient care settings. Typically, for residents to gain the necessary knowledge, skills, and experience to practice independently upon graduation, radiology training programs must provide an optimal balance between resident education and clinical obligations. We describe our experience adapting to the challenges in educational interruptions and clinical work reassignments of 41 interventional and diagnostic radiology residents at a large academic center. We highlight opportunities for collaboration and teamwork in creatively adjusting and planning for the short and long-term impact of the pandemic on resident education. This experience shows how the residency educational paradigm was shifted during a pandemic and can serve as a template to address future disruptions.

Cross-Residency Radiologic/Pathologic Correlation Curriculum: Teaching Correlation of Surgical Specimens With Imaging.

The College of American Pathologists expects pathologists to attain competency in radiologic/pathologic correlation, including correlation of histopathologic findings with imaging findings. While pathology residents appreciate the importance of radiologic/pathologic correlation, their lack of experience and confidence in interpreting imaging studies deters them from obtaining specimen radiographs and reviewing preoperative imaging studies. Formal training in this domain is lacking. A cross-residency curriculum was developed to help pathology residents build basic skills in the correlation of surgical specimens with preoperative imaging and specimen radiographs. Didactic sessions were prepared by 3 pairs of radiology and pathology residents with guidance from radiology and pathology attendings in the subspecialty areas of breast, musculoskeletal, and head and neck. The authors describe the development, implementation, and assessment of the curriculum. A total of 20 pathology residents attended the sessions, with 7 completing both the pre- and postintervention surveys. These residents gained confidence in their ability to interpret specimen radiographs and to select specimens to evaluate with radiography. They gained an appreciation of the importance of collaboration with radiologists in evaluating specimens and of viewing preoperative imaging studies to guide gross examination and dissection. They reported obtaining specimen radiographs and viewing preoperative imaging studies more frequently after attending the sessions. Innovative solutions such as this cross-residency educational initiative offer a potential solution to fulfill the radiologic/pathologic correlation competency standard for pathology residents and may be replicable by other residency programs and academic institutions.

Trainee and Attending Perspectives on Remote Radiology Readouts in the Era of the COVID-19 Pandemic.

RATIONALE AND OBJECTIVES: Social distancing mandates due to COVID-19 have necessitated adaptations to radiology trainee workflow and educational practices, including the radiology "readout." We describe how a large academic radiology department achieved socially distant "remote readouts," provide trainee and attending perspectives on this early experience, and propose ways by which "remote readouts" can be used effectively by training programs beyond COVID-19. MATERIALS AND METHODS: Beginning March 2020, radiologists were relocated to workspaces outside of conventional reading rooms. Information technologies were employed to allow for "remote readouts" between trainees and attendings. An optional anonymous open-ended survey regarding remote readouts was administered to radiology trainees and attendings as a quality improvement initiative. From the responses, response themes were abstracted using thematic analysis. Descriptive statistics of the qualitative data were calculated. RESULTS: Radiologist workstations from 14 traditional reading rooms were relocated to 36 workspaces across the hospital system. Two models of remote readouts, synchronous and asynchronous, were developed, facilitated by commercially available information technologies. Thirty-nine of 105 (37%) trainees and 42 of 90 (47%) attendings responded to the survey. Main response themes included: social distancing, technology, autonomy/competency, efficiency, education/feedback and atmosphere/professional relationship. One hundred and forty-eight positive versus 97 negative comments were reported. Social distancing, technology, and autonomy/competency were most positively rated. Trainees and attending perspectives differed regarding the efficiency of remote readouts. CONCLUSION: "Remote readouts," compliant with social distancing measures, are feasible in academic radiology practice settings. Perspectives from our initial experience provide insight into how this can be accomplished, opportunities for improvement and future application, beyond the COVID-19 pandemic.

Reducing Burnout Among Radiology Trainees: A Novel Residency Retreat Curriculum to Improve Camaraderie and Personal Wellness - 3 Strategies for Success.

OBJECTIVES: To describe a residency retreat curriculum established to improve wellness and reduce burnout within a radiology residency. METHODS: A wellness retreat was created and implemented within a large academic medical center's radiology residency. The retreat curriculum was designed by a Radiology Residency Wellness Committee and was supported by departmental funding. The retreat curriculum centered on 3 strategies for success: teambuilding and bonding, Design Thinking, and guided reflection. A questionnaire was distributed at the end of the retreat, asking 12 questions in 5-point Likert format to assess resident satisfaction with different components of the retreat, as well as open-ended questions to more deeply assess the effects of the retreat on the residency experience and personal wellness in our radiology residency. Questionnaire results were summarized using frequency and percentages. Open-ended responses were qualitatively analyzed using the constant comparative method. RESULTS: Thirty-seven of 41 residents (90%) in our radiology residency participated in the retreat. Thirty-five of the 37 residents (95%) participated in the postretreat questionnaire, with 33 of 37 residents (89%) completing the entire questionnaire. Thirty-two of 33 responders (97%) anticipated the retreat would improve their residency experience, and 27 of 33 responders (82%) indicated the retreat would improve their personal wellness. Based upon the open-ended responses, improved camaraderie was the major benefit of the retreat cited by the majority of residents. CONCLUSION: A departmentally sponsored radiology residency retreat may improve personal wellness and reduce burnout.
