  Follow-Up or Forget It? Managing Indeterminate T1-Hypointense Spine Lesions

  Aug 18, 202610 min

  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 outcomes of 278 such lesions and finds an overall malignancy rate of only 2%, with all malignant lesions representing metastases in patients with known or concurrently diagnosed extraskeletal metastatic disease and no primary malignant bone tumors identified. Dr. Vilanilam reviews the imaging features of these lesions, the importance of incorporating the patient's oncologic history into risk assessment, and the implications for follow-up recommendations. The findings suggest that short-interval imaging may be appropriate when there is meaningful concern for metastatic disease, while follow-up may not be necessary for low-risk patients without aggressive imaging features or extraskeletal metastatic disease.

  Traumatic Hemorrhage Expansion feat. Caline Azzi

  Aug 12, 202616 min

  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.

  Seeing It First: How Recognizing Sinking Flap Syndrome Can Change Patient Outcomes

  Jul 2, 202612 min

  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.

  CTA Carotid Plaque-RADS

  May 28, 202618 min

  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.

  Optimizing CSF-Venous Fistula Detection

  Apr 14, 202610 min

  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.
