| 5/28/26 | ![]() CTA Carotid Plaque-RADS | 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.

Carotid Plaque-RADS: Inter- and Intrareader Agreement and Learning Curve Analysis in CTA CTA-Based Carotid Plaque-RADS Classification Improves Risk Stratification for Ischemic Cerebrovascular Events | — | ||||||
| 4/14/26 | ![]() Optimizing CSF-Venous Fistula Detection | 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 enhance fistula detection in patients with spontaneous intracranial hypotension. | — | ||||||
| 3/31/26 | ![]() Traumatic SAH Risk Stratification | 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 unnecessary repeat CT scans while focusing surveillance on patients most likely to deteriorate. | — | ||||||
| 3/25/26 | ![]() Poststroke Collaterals on MRI feat. Cynthia Greene | 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 vessels was associated with worse short-term neurologic outcomes, even among successfully reperfused patients, suggesting persistent FLAIR hyperintense vessels may mark ongoing perfusion abnormality or possible no-reflow physiology. | — | ||||||
| 3/3/26 | ![]() CTA for Strangulation feat. Jimmy Moon | 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. | — | ||||||
| 2/19/26 | ![]() Menière Disease Associated Vestibular Aqueduct Hypoplasia feat. Amy Juliano | 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 serves as a practical surrogate for a mature vestibular aqueduct orientation, reliably excluding the hypoplastic endotype and identifying ears that do not belong to this high-risk subgroup. In contrast, in the degenerative endotype of Menière disease, retrolabyrinthine bone thickness is more variable and does not follow this simple threshold pattern, so CT features must be interpreted in a broader clinical and imaging context. Read the AJNR articles mentioned in this episode: "Postnatal Development of the Vestibular Aqueduct Trajectory on CT: Establishing Age-Specific Norms to Distinguish Normal from Arrested (Hypoplastic) Development" "Retrolabyrinthine Bone Thickness as a Radiologic Marker for the Hypoplastic Endotype in Menière Disease". | — | ||||||
| 2/4/26 | ![]() Post-Radiation Carotid Disease | 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 just degree of narrowing, to help prevent stroke in this high‑risk group. | — | ||||||
| 1/27/26 | ![]() CT Perfusion Timing feat. Amir Khadivi | 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 acquisition window. | — | ||||||
| 1/7/26 | Vertebral Artery Injury Grading | 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. | — | ||||||
| 12/19/25 | ![]() AI intracranial aneurysm detection feat. Babatunde Akinpelu | In this AJNR Author Interview, Dr. Francis Deng discusses with Dr. Babatunde Akinpelu the article "Assessing the Accuracy of Artificial Intelligence in Detecting Intracranial Aneurysms in a Clinical Setting Relative to Neuroradiologists." Neuroradiologists performed better than a commercial AI program for intracranial aneurysm detection in sensitivity and accuracy, while achieving comparable specificity. Common failure modes are reviewed. | — | ||||||

In this large cohort, the yield of MRI for relevant findings was 5.9%, including tumors in less than 3%. The spectrum of pathology is illustrated | — | ||||||
| 11/7/25 | SIH-RADS: Structured Reporting for CSF Leaks in Dynamic CT Myelography | In this AJNR article summary, Dr. Francis Deng reviews an article by Dr. Andrew Callen and colleagues entitled "Enhancing Clarity in Dynamic Myelography Reporting: Results of a Survey of Patients and Referring Providers Evaluating a Standardized Reporting System in the Myelographic Workup of Patients with Suspected Spontaneous Intracranial Hypotension". The SIH-RADS system provides a structured manner of reporting results of dynamic CT myelography that are clear, actionable, and preferred by both patients and providers. | — | ||||||
| 10/31/25 | ![]() Sinus CT in Neutropenic Fever feat. Rohini Nadgir | In this AJNR Author Interview, Dr. Francis Deng discusses with Dr. Rohini Nadgir the article "Clinical Impact of Sinus CT Surveillance Imaging among Febrile Neutropenic Patients: A Retrospective Observational Study." CT sinus imaging results, positive or negative, did not directly alter clinical management in this patient population, suggesting that routine sinus CT may be a low-yield examination in the setting of febrile neutropenia. | — | ||||||
| 10/14/25 | ![]() Ultrasound for Neck NI-RADS 2 Evaluation | Podcast editor Francis Deng explores a recent AJNR article, "Diagnostic Performance of Ultrasound in Neck Node NIRADS Category 2." Bottom line is: Ultrasound, with targeted FNA, can accurately determine tumor recurrence in patients with NI-RADS 2 (low suspicion) lymph node findings during surveillance of head and neck cancer. | — | ||||||
