This study examines the outcomes...

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 Artic...

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 - includ...

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 st...

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 confide...

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 predic...

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 a...

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...

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 de...

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...

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.

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 spe...

In this AJNR article summary, Dr. Francis  Deng  reviews a study, from corresponding author Dr. Katherine Reinshagen, entitled " Retrospective Review of MR Findings in Sudden Sensorineural Hearing Loss and Associated Clinical Features ". 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

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...

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 ."

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.
