"The results of our study show that Carotid Plaque-RADS can be applied to CTA imaging with a very good degree of reproducibility among readers of different levels of experience. Further studies are needed to test the interreader agreement among readers with similar experience."

"CFE in sickle cell–related hemoglobinopathies is more common in complex hemoglobinopathies with otherwise milder disease course and is typically more fulminant compared with traumatic CFE. MRI findings follow a pattern with scattered foci of restricted diffusion, known as the starfield pattern.

"This case series examines the histopathologic features of perineural tissues at the spinal level of CVFs across 5 patients with SIH who underwent surgical ligation and resection of the affected nerve root. Vascular alterations were found in all specimens."

We are thrilled to announce the launch in early 2026 of AJNR: Clinical Practice, a new journal, as the next chapter of Neurographics within the AJNR family of journals.

"The results of this study demonstrate neuroradiology fellowship PD consensus on interpretive volume expectations for neuroradiology fellows from 20 daily cases in the first half of the academic year increasing to 30 in the second half, corresponding with increases in fellow proficiency."

Expected Trainee Interpretive Volumes and Potential Threats to Neuroradiology Program Viability: A Survey of Neuroradiology Fellowship Program Directors
BACKGROUND AND PURPOSE: Nationally clinical volumes are rising, putting greater pressure on radiologists to read more and in turn jeopardizing the academic missions of many training programs. The purpose of this study was to survey neuroradiology fellowship program directors (PDs) to identify reasonable expected trainee and faculty interpretive volumes, common barriers to study interpretation, and threats to fellowship program viability. MATERIALS AND METHODS: This was an institutional review board–approved survey study disseminated to neuroradiology fellowship PDs through the American Society of Neuroradiology. This Web-based survey included basic program information regarding practice setting, faculty size, fellowship size, and multiple questions related to interpretative volumes, barriers to study interpretation, threats to program viability, etc. Summary statistics were computed for count and rank variables. For survey questions by using ranking, cumulative ranks across all institutions were computed with a statistical ranking procedure based on Savage scores. RESULTS: Forty-three of 85 PDs responded to the survey. Median daily interpretive expectations for fellows were 20 daily cases during the first 6 months of the year and 30 during the second 6 months. Median daily interpretive expectations for faculty working with fellows was 32 daily cases during the first 6 months of the year and 38.5 during the second 6 months. Telephone calls from technologists and referring clinicians and protocoling were identified as major barriers to interpreting studies. Perceived major threats to program viability included increasing case volumes, understaffing, and burnout. CONCLUSIONS: Reasonable interpretive volumes determined by fellowship directors ranged between 20–30 daily cases for fellows and 32–38.5 daily cases for faculty working with fellows. Common barriers to interpretation were related to phone call interruptions and protocoling. Perceived major program viability threats remain centered on increasing clinical volumes and burnout.

"Our study evaluated the rate of unintended Onyx migration into the subarachnoid space in patients who underwent transvenous embolization of CVFs. We did not find cases of Onyx in the CSF at the embolization site or distally in the lumbar spine. This speaks to the safety profile."

"This study demonstrates that the distribution of injectate during CT-guided epidural patching is influenced by multiple factors, including spinal level, PV, composition, and injection approach. These findings support the hypothesis that procedural and patient-specific factors impact patch dist."

"We have shown that there is a high detection rate of intracranial abnormalities on iuMRI of fetuses with small head sizes but normal intracranial findings on antenatal USS. In most cases, the intracranial abnormalities shown on iuMRI brought about a change in prognostic information available."
