AJNR Podcasts

In this AJNR Podcast author interview, Dr. Francis Deng speaks with Dr. Caline Azzi about recent studies identifying imaging and clinical predictors of expansion in traumatic subdural, subarachnoid, and intraparenchymal hemorrhage. Hemorrhage size, multicompartment injury, coagulopathy, mass effect, and neurologic status may help determine which patients truly need routine repeat CT.   Related Articles: Risk Stratification for Traumatic SAH Enlargement and Surgical Intervention: Guides to Follow-Up Imaging in Patients with Trauma Predictive Factors for Traumatic Intraparenchymal Hemorrhage Expansion and Its Clinical Outcomes Improving the management of acute subdural hematomas; identifying characteristics associated with acute subdural hematoma size and expansion    

In this AJNR Article Summary, Dr. George Vilanilam discusses the article, "Sinking Flap Syndrome: Risk Factors, Outcomes, and the Role of Neuroradiology in Cranioplasty Timing." Sinking flap syndrome is a common yet frequently underrecognized complication of decompressive craniectomy, with imaging findings often preceding clinical deterioration. Recognition and reporting of key features - including a markedly sunken flap, ventricular compression, and significant midline shift (8 mm or greater) were associated with a two-fold reduction in time to cranioplasty highlighting the important role neuroradiologists can play in expediting definitive treatment and improving patient care.

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.
