The American Journal of Neuroradiology (AJNR) is a peer-reviewed journal publishing original research and reviews on diagnostic, interventional, and functional imaging of the brain, head, neck, and spine. The monthly podcasts cover Editor's Choices, Fellows' Journal Club selections, and include author interviews. Hosted by Francis Deng and George K. Vilanilam.

Follow-Up or Forget It? Managing Indeterminate T1-Hypointense Spine Lesions
Follow-Up or Forget It? Managing Indeterminate T1-Hypointense Spine Lesions Aug 18, 2026 611 In this podcast episode, Dr. Vilanilam discusses "Indeterminate T1-Hypointense Spine Lesions: Prevalence of Malignancy in the Absence of Aggressive Imaging Features," by first author Barkovich. Indeterminate low-T1-signal vertebral lesions are commonly encountered on spine MRI, but deciding which lesions require additional imaging or follow-up can be challenging. This study examines the o
Traumatic Hemorrhage Expansion feat. Caline Azzi
Traumatic Hemorrhage Expansion feat. Caline Azzi Aug 12, 2026 956 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. Rel
Seeing It First: How Recognizing Sinking Flap Syndrome Can Change Patient Outcomes
Seeing It First: How Recognizing Sinking Flap Syndrome Can Change Patient Outcomes Jul 2, 2026 703 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 -
CTA Carotid Plaque-RADS
CTA Carotid Plaque-RADS May 28, 2026 1053 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 c
Optimizing CSF-Venous Fistula Detection
Optimizing CSF-Venous Fistula Detection Apr 14, 2026 590 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
Traumatic SAH Risk Stratification
Traumatic SAH Risk Stratification Mar 31, 2026 517 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
Poststroke Collaterals on MRI feat. Cynthia Greene
Poststroke Collaterals on MRI feat. Cynthia Greene Mar 25, 2026 867 In this AJNR Author Interview, Dr. Francis Deng speaks with Dr. Cynthia Greene about her article, "Posttreatment Follow-Up MR Imaging Biomarkers of Collateral Status Are Associated with Short-Term Outcomes in Large-Vessel Acute Ischemic Stroke." In a retrospective study of follow-up MRI after anterior-circulation large-vessel occlusion stroke, a greater burden of FLAIR hyperintense vessel
CTA for Strangulation feat. Jimmy Moon
CTA for Strangulation feat. Jimmy Moon Mar 3, 2026 644 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.
Menière Disease Associated Vestibular Aqueduct Hypoplasia feat. Amy Juliano
Menière Disease Associated Vestibular Aqueduct Hypoplasia feat. Amy Juliano Feb 19, 2026 1781 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 endolymp
Post-Radiation Carotid Disease
Post-Radiation Carotid Disease Feb 4, 2026 608 In this AJNR Article Summary, Dr. George Vilanilam discusses the article, "Biphasic Progression of Radiation-Induced Carotid Stenosis: The Predictive Role of Low-Density Plaque". Low‑density carotid plaque on imaging may signal accelerated stenosis progression in post‑radiation patients, highlighting the need for earlier intervention and a shift toward evaluating plaque composition, not j
CT Perfusion Timing feat. Amir Khadivi
CT Perfusion Timing feat. Amir Khadivi Jan 27, 2026 967 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 trun
Vertebral Artery Injury Grading
Vertebral Artery Injury Grading Jan 7, 2026 681 Dr. Francis Deng discusses the article by Vankawala et al. entitled "Evaluating the Role of Imaging Markers in Predicting Stroke Risk and Guiding Management after Vertebral Artery Injury: A Retrospective Study." The Biffl grading scale assess blunt cerebrovascular injury severity, but its prognostic validity for vertebral artery injuries with respect to stroke risk remains controversial.
