In this AJNR Article Summary, Dr. Francis Deng reviews CTA-based Carotid Plaque-RADS and its role beyond stenosis grading. He explains the key imaging features that define plaque vulnerability, then highlights two AJNR studies showing that the system is learnable, reproducible, and clinically meaningful for predicting future stroke risk, especially in patients with only mild or moderate carotid stenosis.

In this AJNR Article Summary, Dr. George Vilanilam discusses the article, " Maximizing the Conspicuity of Cerebrospinal Fluid–Venous Fistulas on Computed Tomography Myelography: Assessment of Contrast Density and Timing Effects ." Contrast density, not just timing, plays the dominant role in detecting CSF-venous fistulas, with higher subarachnoid contrast significantly improving diagnostic confidence. These findings support prioritizing contrast pooling strategies during CT myelography to enhanc...

In this AJNR Article Summary, Dr. George Vilanilam discusses the article, " Risk Stratification for Traumatic Subarachnoid Hemorrhage Enlargement and Surgical Intervention: Guides to Follow-Up Imaging in Patients with Trauma ." Not all traumatic subarachnoid hemorrhages behave the same - risk factors such as coagulopathy, concurrent intracranial hemorrhage, and low Glasgow Coma Scale scores predict hemorrhage progression and need for intervention. A risk-stratified imaging approach may reduce un...

In this AJNR Author Interview, Dr. Francis Deng speaks with Dr. Jimmy Moon about his article, " Use of CTA in Strangulation Evaluation ". In a retrospective review, the yield of CTA neck for blunt cerebrovascular injury in patients who presented after strangulation was 1 in 138 (0.7%), suggesting the broad use of CTAs in this setting may be of low value.

In this AJNR Podcast Author Interview, Dr. Francis Deng and Dr. Amy Juliano discuss how CT can subtype Menière disease by assessing the vestibular aqueduct and adjacent bone. During normal childhood, the angular trajectory of the vestibular aqueduct progressively narrows; an angle greater than 120 degrees after age 12 indicates adult-persistent hypoplasia and thus the hypoplastic endolymphatic sac endotype rather than normal maturation. A retrolabyrinthine bone thickness of at least 1.2 mm serve...

In this AJNR Fellows' Journal Club article summary, Dr. Francis Deng and Dr. Amir Khadivi discuss the article by Proner et al., " Impact of Clinical and Radiologic Factors on CTP Timing in Acute Ischemic Stroke. " They discuss the authors' findings that cardiac arrhythmias and older age are independent predictors of nondiagnostic CTP exams. Specifically, these factors often lead to the truncation of reference vessel time-attenuation curves that fail to reach equilibrium within a 45-second acquis...
