RESUMEN
BACKGROUND AND PURPOSE: Brain Arteriovenous malformations (AVMs) are congenital anomalies of the cerebrovascular system, often discovered incidentally or through symptomatic presentations such as intracranial hemorrhage, seizure, headache, or neurological deficits. Various treatment modalities exist for AVMs, including radiosurgery, a treatment modality that is noninvasive and efficient. Accurate imaging is crucial for risk assessment, treatment planning, and monitoring of these patients before and after radiosurgery. Currently, Digital Subtraction Angiography (DSA) stands as the preferred imaging modality. Despite its efficacy, DSA is notably invasive, presenting inherent risks to the patients. This systematic review and meta-analysis aim to evaluate the efficacy of magnetic resonance imaging (MRI) sequences for monitoring brain AVMs after radiosurgery. DATA SOURCE: A comprehensive search of PubMed, Scopus, Web of Science, and Embase databases was done and methodological quality assessment performed with the QUADAS-2 checklist diagnostic test accuracy. DATA ANALYSIS AND SYNTHESIS: We utilized the bivariate random-effects meta-analysis model (BRMA) with STATA/MP 17 software for data analysis. No significant publication bias was detected.14 studies were eligible for qualitative and quantitative analysis. MRI offers high sensitivity (85%) and specificity (99%) in detecting residual AVMs. Different MRI sequences, including 3DTOF MRA, 4D-MRA, and ASL demonstrated varying diagnostic accuracies with area under the curve (AUC) of 0.92, 0.97, and 0.96 respectively. 4D-MRA exhibited a sensitivity of 72% and specificity of 99%, ASL showed a sensitivity of 90% and specificity of 92% while 3D-TOF MRA showed 90% sensitivity and 87% specificity. LIMITATIONS: Meta-regression did not fully explain the sources of heterogeneity. Only one study assessed the SWAN method, and most studies involved small participant groups with varied MR techniques and sequences. Additionally, the retrospective nature of most studies may introduce bias, warranting cautious interpretation of the results. CONCLUSIONS: MRI sequences show acceptable diagnostic performance in post-radiosurgery monitoring of brain AVMs, with ASL and 4D-MRA showing acceptable diagnostic accuracy. Combining different MRI sequences may further enhance diagnostic reliability. However, Further investigation is needed to assess whether MRI sequences can serve as a feasible substitute for DSA, taking into account their risk-benefit profile, with the potential to establish them as the recommended standard.
RESUMEN
RATIONALE AND OBJECTIVES: The number of international medical graduates (IMGs) entering radiology residencies and neuroradiology fellowships averaged 9.7% and 20.9% from 2021 to 2023, respectively. We aimed to determine whether IMG graduates are populating leadership roles at a proportionate rate in diagnostic radiology (DR) and neuroradiology. MATERIALS AND METHODS: We surveyed 191 DR program directors, 94 neuroradiology program directors (PDs), 192 chairs of radiology, and 91 directors of neuroradiology inquiring about their original citizenship and medical school (American Medical Graduates [AMG] vs IMG). We reviewed institutional websites to obtain missing data and recorded H indices for each person using Scopus. RESULTS: We confirmed the original citizenship and medical school location in 61-75% and 93-98% of each leadership group. We found that 16.2% of DR program directors, 43.7% of neuroradiology PDs, 28.5% of Chairs, and 40.6% of neuroradiology directors were not originally US citizens. The IMG rate was 18/188 (9.6%), 20/90 (22.2%), 26/186 (14.0%), and 19/85 (22.4%) for the same groups respectively. The most common country of origin and medical school cited was India for all leadership groups. IMGs had a median H index of 14 while AMG 10, significantly different (p = 0.021) CONCLUSION: Compared to the rate of diagnostic and neuroradiology trainees entering from 2021 to 2023, IMGs are proportionately represented at the leadership positions studied. The H index of the IMGs was higher than AMG. We conclude that IMGs have made substantial and proportionate inroads in radiology and neuroradiology leadership.
RESUMEN
PURPOSE: Radiology faculty across various specialties have been reported to receive an average of 20.7 invitations to submit manuscripts to bogus journals and 4.1 invitations to speak at unsuitable events over a two-week span. Radiology trainees also receive a fair number of unsolicited invitations from unknown senders to submit manuscripts and speak at meetings. Trainees can be more vulnerable to predatory invitations due to potential naivety. We aimed to determine the prevalence of these spam invitations received by radiology trainees. MATERIAL AND METHODS: The designed survey for evaluating the experience of radiology trainees regarding phishing scams of predatory publications and conferences was sent to radiology residency and neuroradiology fellowship program leadership to redistribute amongst their trainees, and was advertised on social media platforms. The survey was first sent out on September 28, 2023, and was closed two weeks later October 12, 2023. Spearman's correlation, univariable and multivariable linear regression analyses were performed. RESULTS: Our study included 151 respondents who completed the survey. Of the survey respondents, 53 % reported receiving unsolicited emails from predatory publications (mean = 6.76 ± 7.29), and 32 % reported receiving emails from fraudulent conferences (mean = 5.61 ± 5.77). Significant positive correlation was observed between number of unsolicited email invitations with number of PubMed indexed publications, number as corresponding author, number in open access journals and number of abstract presentations. CONCLUSIONS: Trainees in radiology receive many unsolicited invitations to publish papers as well as to present at meetings that are not accredited. This could lead to wasted time and financial resources for unsuspecting trainees.
RESUMEN
BACKGROUND: Cervical spine computed tomography (CSCT) scans are frequently performed in older emergency department (ED) trauma patients based on the 65-year-old high-risk criterion of the Canadian Cervical Spine Rule (CCR). We sought to determine the positivity rate of CSCT scans in symptomatic and asymptomatic patients to assess the current applicability of age in the CCR. METHODS: We reviewed CSCT ED reports from two institutional hospitals from 2018 to 2023. The primary variable was age; however, we also recorded fracture types and sites and type of treatments. Patients were separated into symptomatic and asymptomatic cohorts. We used a Fisher's exact test to compare variables between the asymptomatic and symptomatic groups and chi-square tests for comparison between age groups. RESULTS: Of 9455 CSCTs performed in patients ≥ 65 years, 192 (2.0%) fractures were identified (113 females); 28 (0.30%) were in asymptomatic patients. The rates of fractures (1.6%) and asymptomatic fractures (0.18%) were lowest in the 65- to 70-year age group. There were no distinguishing features as to the level or part of the vertebra fractured or surgical treatment rate between asymptomatic and symptomatic patients. CONCLUSIONS: Cervical spine fractures in posttrauma patients ≥ 65 years are uncommon, with the lowest incidence in those 65 to 70 years old. Excluding asymptomatic individuals aged 65-70 from routine CSCT presents a minimal risk of missed fractures (0.18%). This prompts consideration for refining age-based screening and integrating shared decision making into the clinical protocol for this demographic, reflecting the low incidence of fractures and the changing health profile of the aging population.
RESUMEN
RATIONALE AND OBJECTIVES: Literature shows that discrimination has been pervasive in the field of medicine. The aim of this study was to collect experiences related to discrimination among US radiology residents, including type and source, as well as the residents' perception on lectures about discrimination and harassment. We also explored the barriers to reporting, and suggested strategies to overcome them. MATERIAL AND METHODS: Following Institutional Review Board (IRB) approval, an online survey was sent to program directors and coordinators across the US, who were asked to forward the link to their radiology residents. A reminder email was sent over a period of 4 months. The participants were reassured the survey was confidential and anonymous. RESULTS: Among the respondents, the most reported types of discrimination were based in gender, race and nationality, the majority of which not being reported. The most common perpetrators were attending radiologists, co-residents, technologists, and patients. The main barriers for reporting were fear of retaliation, confidentiality concerns, and skepticism about a positive outcome. CONCLUSION: Our study examines some experiences of discrimination shared by residents during their training, with gender and race being the most common causes. This sheds light into a hidden and unspoken issue and highlights the need for more active discussions in radiology on microaggressions and implicit bias. Our data can guide future studies as well as residency programs to build effective strategies to address discrimination, aiming for sustainable changes.

Despite decades of faculty professional development programs created to prepare women for leadership, gender inequities persist in salary, promotion, and leadership roles. Indeed, men still earn more than women, are more likely than women to hold the rank of professor, and hold the vast majority of positions of power in academic medicine. Institutions demonstrate commitment to their faculty's growth by investing resources, including creating faculty development programs. These programs are essential to help prepare women to lead and navigate the highly matrixed, complex systems of academic medicine. However, data still show that women persistently lag behind men in their career advancement and salary. Clearly, training women to adapt to existing structures and norms alone is not sufficient. To effectively generate organizational change, leaders with power and resources must commit to gender equity. This article describes several efforts by the Office of Faculty in the Johns Hopkins University School of Medicine to broaden inclusivity in collaborative work for gender equity. The authors are women and men leaders in the Office of Faculty, which is within the Johns Hopkins University School of Medicine dean's office and includes Women in Science and Medicine. Here, we discuss potential methods to advance gender equity using inclusivity based on our institutional experience and on the findings of other studies. Ongoing data collection to evaluate programmatic outcomes in the Johns Hopkins University School of Medicine will be reported in the future.

We sought to determine the diagnostic accuracy of radiomics features in predicting HPV status in oropharyngeal squamous cell carcinoma (SCC) compared to routine paraclinical measures used in clinical practice. Twenty-six articles were included in the systematic review, and thirteen were used for the meta-analysis. The overall sensitivity of the included studies was 0.78, the overall specificity was 0.76, and the overall area under the ROC curve was 0.84. The diagnostic odds ratio (DOR) equaled 12 (8, 17). Subgroup analysis showed no significant difference between radiomics features extracted from CT or MR images. Overall, the studies were of low quality in regard to radiomics quality score, although most had a low risk of bias based on the QUADAS-2 tool. Radiomics features showed good overall sensitivity and specificity in determining HPV status in OPSCC, though the low quality of the included studies poses problems for generalizability.
RESUMEN
BACKGROUND: Financial security and retirement planning are essential for all medical professionals including radiology residents. Given the available discretionary income during residency it is crucial to have insights into investment. We aimed to assess the prevalence of retirement plans offered to radiology residents, the available choices, and their degree of participation. METHODS: Two surveys were created using Qualtrics platform, one targeting program directors and another one oriented to radiology residents with items focused on demographic, financial status, offered plans, and participation. Analysis was performed using chi square whenever appropriate using Qualtrics platform. P values less than 0.05 were considered statistically significant. RESULTS: 199 radiology residents (72.6% attending university-based programs) responded to the survey. 83.7% participated in retirement plans; university-based programs had the highest rate of offering plans; 82.8% vs 70% and 53.8% for university, community and hybrid programs respectively. The most frequently offered retirement plan was a 403(b). Most of the residents (94.3%) started investment in the retirement program as early as PGY1 and PGY2. A considerable proportion of programs lacked formal training on retirement plans; however, residents emphasized the significance of financial education during their residency. CONCLUSION: Radiology residents are more likely to participate in a retirement plan if it is offered by their program. Providing proper guidance by incorporating financial education into radiology residency curricula can optimize residents' decision making and economical planning, leading to a more secure financial future.

BACKGROUND. International medical graduates (IMGs) are a source of physicians who could help alleviate radiologist workforce shortages in the United States. However, IMGs may face barriers in obtaining appropriate visas (e.g., H-1B or O-1 visas) to allow faculty employment. OBJECTIVE. The purpose of this study was to assess the policies and experiences of U.S. academic radiology departments in offering visas to IMGs applying for faculty positions. METHODS. A web-based survey on policies and experiences in offering visas to IMG faculty candidates was distributed to chairs of U.S. radiology departments with a diagnostic radiology training program recognized by the National Resident Matching Program. Individual survey questions were optional. The initial survey and subsequent reminders were sent from October 7, 2022, through November 7, 2022. RESULTS. The survey response rate was 81% (143/177). A total of 24% (28/115), 38% (44/115), 17% (20/115), and 20% (23/115) of departments offered H-1B visas to IMG faculty frequently, sometimes, rarely, and never, respectively; 3% (3/113), 27% (31/113), 22% (25/113), and 48% (54/113) of departments offered O-1 visas frequently, sometimes, rarely, and never, respectively. However, 41% (46/113) and 5% (6/113) of departments had default policies of offering H-1B and O-1 visas for IMG faculty candidates, respectively. The most common reasons given for why departments did not offer visas included, for both H-1B and O-1 visas, the time-consuming process, lack of reliability of candidates' starting time, and the expense of the visa application; for O-1 visas, the reasons given also included lack of expertise. A total of 15% (16/108) of departments set their own visa policies, 75% (81/108) followed institutional policies, and 10% (11/108) followed policies set by other entities (e.g., state government). CONCLUSION. Although to at least some extent most U.S. academic radiology departments offer H-1B and O-1 visas for IMGs seeking faculty positions, use of such visas typically is not the departments' default policy. A variety of barriers contributed to visas not being offered. The departments' visa policies were primarily determined at the institutional level. CLINICAL IMPACT. The identified barriers faced by U.S. academic radiology departments in offering visas to IMG faculty candidates impact the role of IMGs in helping to address radiologist workforce shortages.

The supplemental ERAS application that includes three components: past experiences, geographic preferences, and program signals was introduced in 2022 to complement the standard ERAS CV material. The goal was to help programs identify optimal candidates to interview and to improve the chances of applicants being invited for interviews at programs that align with their goals and interests. Based on limited data, Program signal is the most emphasized component by the programs. Applicants should realize that programs have used signals to determine who to interview (aligned with AAMC guidance), and to determine the program's candidate rank list (contrary to AAMC guidance). We have herein suggested options for leveraging benefits from the ERAS supplemental application which has now been incorporated into the full ERAS application.

Internal watershed infarcts (IWIs) occur at the junction of the deep and superficial perforating arterial branches of the cerebrum. Despite documentation in the radiology literature, IWIs are rarely encountered at the time of autopsy. Here, we report the case of a 59-year-old incarcerated male who was brought to the emergency department after being found unresponsive on the floor of his jail cell. Initial examination and imaging demonstrated right-sided hemiplegia, aphasia, right facial droop, and severe stenosis of the left middle cerebral artery, respectively. Repeat imaging 4 days after admission and 26 days before death demonstrated advanced stenosis of the intracranial, communicating segment of the right internal carotid artery, a large acute infarct in the right posterior cerebral artery territory, and bilateral deep white matter ischemic changes with a right-sided "rosary-like" pattern of injury that is typical of IWIs. Postmortem gross examination showed that the right deep white matter lesion had progressed to a confluent, "cigar-shaped" subacute IWI involving the right corona radiata. This is the first well-documented case of an IWI with radiologic imaging and photographic gross pathology correlation. This case uniquely highlights a rarely encountered lesion at the time of autopsy and provides an excellent visual representation of internal watershed neuroanatomy.
RESUMEN
Background: Cervical annular fissures (AFs) have not been studied specifically as to their prevalence, imaging features, and persistence over time. We sought to determine the prevalence and natural history of cervical AFs. We hypothesized that these are static lesions that are not prevalent in the population. Methods: This was a cross-sectional retrospective study of cervical MRI examinations performed between 2011-2021. We retrospectively reviewed the studies of 115 consecutive patients (63 female, 52 male) who had 2 or more MRI studies of the cervical spine to identify (1) imaging features of cervical AFs on various pulse sequences, (2) the concurrence of disc bulges/herniations, (3) changes in those imaging findings over time (mean follow-up 39.3 months) and (4) rate at which cervical AFs were mentioned in radiology reports. 620 initial and follow-up studies were reviewed. Results: 50/115 (43.5%) patients had cervical AFs; 21 patients had a single AF and 29 patients had multi-level AFs (total 109 AFs). The most common levels affected were C4-C5 (28%, n = 31) and C5-C6 (27%, n = 30). All cervical AFs were hyperintense on T2WI and, over time, 95% (n = 104/109) of the AFs remained hyperintense; 22% (n = 25) showed less hyperintensity, 10% (n = 11) more hyperintensity, and 60% (n = 66) the same hyperintensity. 5 AFs (4%) resolved completely. Only 2 (8%) of 25 cervical AFs enhanced with gadolinium. The rate of concomitant disc bulges and herniations was 71% (n = 78) and 22% (n = 24) respectively. The presence of cervical AFs did not increase the risk of progression to bulges or herniations. None of the cervical AFs were mentioned in the radiology reports. Conclusions: Cervical AFs occurred in 43.5% of patients but were rarely reported. They usually remained bright on T2W but their brightness could vary over time. Cervical AFs were often associated with disc bulges/herniations and enhanced less frequently (8%) than lumbar disk AFs.
RESUMEN
PURPOSE: To assess the effectiveness of an online, case-based interactive course in emergency neuroradiology to prepare radiology residents for night call in neuroradiology. METHODS: A total of 15 residents participated in a pretest assessment of preparedness for neuroradiology call. After completing a 6-week interactive course incorporating case review, didactic lectures, quiz feedback, and references for further review, the same residents were quizzed on cognitive questions and feelings of readiness to enter the on-call pool for neuroradiology. RESULTS: Knowledge and confidence both significantly increased due to the course. Knowledge-wise, the scores for precourse quiz to postcourse quiz went from 18.4%-72.2% (53.8% increase) in Brain Imaging and went from 22.3%-77.1% (54.8% increase) in Head, Neck, and Spine (P < 0.001 for both). Confidence-wise, residents demonstrated statistically significant increases in all 6 confidence measures. Prior to the course, 29% were not confident, 71% were fairly confident, and 0% were confident/very confident. After the course, 0% were not confident, 43% were fairly confident, and 57% were confident/very confident. Belief in the statement "I can provide high quality Neuroimaging services in the emergency care setting" increased from a confidence score of 1.29-2.57 after training (P = 0.004). Nearly all residents completing their first emergency call reported that they felt more confident reading neuroradiology studies during their call as a direct result of the course. CONCLUSIONS: Completing the multi-pronged interactive, case-based online emergency neuroradiology course led to improved funds of knowledge and feelings of confidence and impacted imaging approach in residents taking neuroradiology call.
RESUMEN
OBJECTIVE: Unsolicited invitations to speak at medical meetings have proliferated as a type of spam email and phishing strategy to scam unsuspecting victims. We sought to determine the prevalence of such invitations to questionable meetings and determine the factors associated with receiving such solicitations. MATERIALS AND METHODS: Data was collected for the number of speakers' invitations received over a 2-week period (April -May 2023) by radiologists of different subspecialties, academic ranks, and histories of publications and speaking engagements in the past 2-5 years. We analyzed the number of invitations received based on the variables. RESULTS: Thirty-three of 45 (73.3%) faculty members received 188 inappropriate invitation emails in the 2-week observation period. The mean number of invitation emails was 4.13 for each faculty (SD: 5.03, range 0-20). There was no correlation between the number of invitations and radiologists' subspecialty, academic rank (3.8 ± 5, 3.0 ± 4, and 5.5 ± 5.7 invitations for full, associate, and assistant professors respectively) and previous legitimate speaker invites. Only 6 (3.2%) out of 188 invitations to speak sent to radiologists were for radiology-related meetings. Having more than 10 publications since 2022 was associated with a 5.0 (1.2, 19.4) times higher odds of receiving more than 4 solicitations. CONCLUSIONS: A total of 73.3% of the faculty surveyed received unsolicited invitations to meetings in the 2-week study period and over 96% of the invitations were unrelated to their field of practice. Our results show that publications since 2022 was the most significant factor associated with receiving more solicitations. CLINICAL RELEVANCE/APPLICATION: Invitations to questionable meetings targeting radiologists are frequent and often are unrelated to their specialties. The risk factors for receiving the invitations are unclear. Understanding these risk factors may enable educators especially junior investigators, to be better prepared to appropriately address such solicitations.
RESUMEN
OBJECTIVE: Annular fissures are common findings on MR studies of the lumbar spine but have not been specifically examined in the thoracic spine. We sought to review the prevalence and stability of MRI imaging features of thoracic annular fissures and the association of thoracic AFs with intervertebral degenerative disk changes. MATERIALS AND METHODS: We surveyed 10 years of MRI studies in which patients had one or more repeated examinations of the thoracic spine. For every annular fissure, we recorded its imaging features on all pulse sequences and the evolution of those imaging findings across all time periods. RESULTS: We reviewed 210 patients and discovered that 66 (31.4%) had at least one thoracic annular fissure. The presence of annular fissures was positively correlated with older age and male gender. The initial annular fissure was always hyperintense on T2WI and annular fissures remained hyperintense on T2WI over time in all cases but showed less hyperintensity in 23.9% (n = 39/163) and more hyperintensity in 4.9% (n = 8/163). The rate of concomitant disk bulges was 85.8% (n = 140/163). Of the 71 annular fissures in which gadolinium-enhanced studies were performed, 20 (28.1%) showed enhancement and 14/20 (70%) annular fissures showed persistent enhancement over time (mean follow-up = 39.6 ± 44.1 months). CONCLUSION: Thoracic annular fissures rarely resolve, remain hyperintense on T2WI, and, if they enhance, that enhancement generally persists.

RATIONALE AND OBJECTIVES: The number of international medical graduates (IMG) in radiology residencies has varied from year to year even as the number of candidates continues to grow. It is unclear from which countries the IMGs are arriving and what visas are being used to accommodate them. MATERIALS AND METHODS: We sent a survey to 195 program directors (PD) in diagnostic radiology (DR) inquiring about the number and nationality of IMG residents in their program, their attitudes about IMG candidates, the performance of their IMG trainees, and the visas that are offered. RESULTS: We received responses from 121 of 195 (62.1%) DR programs (121/149 =81.2% of actionable emails). 80/121 (66.1%) had at least one IMG in their DR residency program and the countries of origin included India (36), Iran (30), Saudi Arabia (24), Egypt (16), Canada (14), Brazil (14), and Pakistan (9), as the most common. While most programs (76/104, 73.1%) offered J1 visas, 23/99 (23.2%) provided H-1B visas to trainees. IMG DR residents overall performed as well as American graduates, with an equal number of PDs saying IMGs performed better and worse than American graduates. PDs' issues with IMGs centered on visas: (1) expense, (2) lack of familiarity, (3) Educational Commission for Foreign Medical Graduates regulations, and (4) time commitment in submitting paperwork. CONCLUSION: Most radiology IMG residents originate from India and Middle Eastern countries. Once enrolled, IMG residents perform similarly to US graduates. However, adding IMG candidates to the training program requires overcoming bureaucratic and monetary hurdles around visas. SUMMARY SENTENCE: Most DR international medical graduate residents are from India or the Middle East. Although their performance is the same as American graduates in general, PDs note the monetary and bureaucratic hassles accompanying their recruitment.

This study examines the patterns of faculty solicitations by open-access (OA) publishers in radiology. The purpose of the research is to determine the factors that predict the likelihood of receiving such solicitations. We recruited 6 faculty members from 7 subspecialties in radiology to collect emails from OA journals for 2 weeks. We assessed the number of publications by each faculty member in 2022 and 2023, the previous 5 years, and entire career in PubMed. For each email, the solicitation was categorized for article submission, article review, and editorial board membership. An invitation to submit a manuscript was the most common type of solicitation received, followed by editorial boards and reviewer invites. Faculty with more than 10 indexed articles in PubMed since January 2022 were significantly more likely to receive article solicitations than those with 10 or fewer publications. Additionally, scholars with more than 40 articles since 2018 were significantly more likely to receive more than 10 article solicitations. Full professors were significantly more likely to receive solicitations to serve on editorial boards. A multivariate linear regression model predicted that publications since 2022 had the highest predictive value for the number of article solicitations and total solicitations. This study provides insight into the patterns of mass communication and various solicitations by OA publishers in radiology. The study highlights the importance of publication productivity as a predictor of article and total email solicitations and of professorial rank for editorial board invitations.
