Purpose: Occipital condyle fractures (OCFs) are classified by the Anderson and Montesano system into Type I (comminuted, minimally displaced), Type II (stable, associated with basilar skull fractures), and Type III (unstable avulsion fractures). We retrospectively analyzed 24,986 cervical spine CT examinations of emergency department patients over five years to determine the incidence and characteristics of OCFs, mechanism of injury, and associated intracranial and cervical spine injuries.

Methods And Materials: The study was IRB-approved and HIPAA compliant.

Article Synopsis
  • The study re-evaluates the Canadian Cervical Spine Rule (CCR) for recommending cervical spine computed tomography (CSCT) on patients aged 65 and older, using trauma data from the last five years.
  • Researchers analyzed fracture rates among trauma patients, distinguishing between those ≥ 65 and < 65 years old, and categorized the fractures into symptomatic or asymptomatic.
  • The results show that the fracture rate for patients ≥ 65 (2.0%) was higher compared to those < 65 (1.6%), with a notable preference for females in the older group, but overall rates were significantly lower than previously reported by the CCR guidelines.

The Canadian Cervical Spine Rule, a clinical decision-making tool for patients post-trauma is often interpreted as recommending cervical spine computed tomography in patients ≥ 65 years old, who sustain a dangerous mechanism of injury, and/or have extremity paresthesias. We retrospectively reviewed 6 years' of emergency department cervical spine computed tomography reports to determine fracture rates in patients ≥ 65, symptomatic or not, who did and did not have a dangerous mechanism. Of those ≥ 65 years old, 240/13925 (1.

Article Synopsis
  • Researchers studied older and younger people to see if there are differences in neck injuries and CT scans for those over and under 65 years old.
  • They looked at data from emergency rooms about 22,000 patients injured over 5 years, focusing on how injuries happened, types of fractures, and treatments.
  • The study found that older people often hurt their necks from falling, while younger people were more likely to hurt themselves in car accidents, and the types of fractures varied between the two age groups.

Objective: Two-tiered preference signaling has been implemented in the radiology residency application system to reduce congestion in the setting of high-volume applications. Signals are an indicator of strong interest that an applicant can transmit to a limited number of programs. This study assessed the impact of program signaling on interview invitations, how applicants strategically used signals based on their application's competitiveness, and applicants' attitudes toward the current signaling system.

Article Synopsis
  • Brain AVMs are congenital vascular abnormalities in the brain that can lead to serious issues like hemorrhage or seizures, and while various treatments exist, accurate imaging is key for effective management, particularly after radiosurgery.
  • Current imaging techniques, like Digital Subtraction Angiography (DSA), are effective but invasive, prompting a systematic review to assess the efficacy of MRI sequences for post-radiosurgery monitoring of AVMs.
  • The analysis of 14 studies revealed that MRI demonstrates high sensitivity (85%) and specificity (99%), with different sequences like 4D MRA and ASL providing varying diagnostic accuracies, making MRI a promising tool for monitoring AVMs without the invasive risks associated with DSA.

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.

Article Synopsis
  • Cervical spine CT scans in older trauma patients (≥65 years) have low fracture detection rates, with only 2% of scans revealing fractures, and just 0.30% in asymptomatic patients.
  • The study analyzed data from 2018 to 2023, comparing symptomatic and asymptomatic groups, and found that the lowest fracture rates were in patients aged 65-70 years.
  • Based on these findings, the authors suggest reconsidering the necessity of routine CT scans for asymptomatic individuals in this age group, advocating for a more tailored screening approach and shared decision-making in treatment options.

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.

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.

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.

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.

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.

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.

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.

Article Synopsis
  • Cervical annular fissures (AFs) were found in 43.5% of patients studied, primarily at the C4-C5 and C5-C6 levels, but were seldom mentioned in radiology reports.
  • Over time, 95% of AFs maintained hyperintensity on T2-weighted MRI, with variations in brightness for some, but only 4% resolved completely.
  • The study indicated that cervical AFs are common but do not appear to increase the risk of developing disc bulges or herniations.

  • Unsolicited invitations to speak at medical meetings are increasing and primarily used as spam and phishing tactics targeting radiologists.
  • In a 2-week study, 73.3% of faculty members received a total of 188 inappropriate invitation emails, with a mean of 4.13 invites per faculty.
  • The majority (over 96%) of these invitations were irrelevant to their specialties, with the most significant factor for receiving more solicitations being a higher publication count since 2022.

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.
