- MR Imaging versus Noncontrast CT for Selecting Patients with Acute Ischemic Stroke of Large Vessel Occlusion for Endovascular Thrombectomy: A Systematic Review and Meta-Analysis
This systematic review and meta-analysis including 7 observational studies found that within the initial 6-hour window, MRI is superior for patient selection despite longer acquisition times. However, beyond 6 hours, rapid EVT should be the focus rather than imaging technique choice, as the benefits of MRI diminish.
- Differentiation between Nonenhancing Tumor in Glioblastoma and Vasogenic Edema Using Diffusion-Weighted and Dynamic Susceptibility Contrast MR Imaging
DWI and PWI MRI measurements provide valuable biomarkers for differentiating nonenhancing glioblastoma from vasogenic edema. The ADC (1.36 x 10-3 mm2/s) and rCBV (1.04) thresholds for solid, nonenhancing glioblastoma showed high sensitivity and specificity. Perilesional T2-FLAIR hyperintensity around enhancing glioblastoma had similar ADC but higher rCBV values (cutoff of 0.42 with good specificity) than vasogenic edema.
- The Effect of Prenatal Marijuana Exposure on White Matter Microstructure and Cortical Morphology during Late Childhood
This cross-sectional study compared children prenatally exposed to marijuana with matched controls with no prenatal exposure. The authors found that prenatal exposure to marijuana was associated with reduced WM microstructural integrity, with observed alterations localizing to the corticostriate circuitry and reduced cortical surface area in the left parahippocampal and right postcentral gyri, regions involved in goal-directed behavior, sensory processing, and emotional regulation.
- Enhancing Clarity in Dynamic Myelography Reporting: Results of a Survey of Patients and Referring Providers Evaluating a Standardized Reporting System in the Myelographic Work-Up of Patients with Suspected Spontaneous Intracranial Hypotension
A standardized scoring system (Spontaneous Intracranial Hypotension Reporting and Data System [SIH-RADS]) designed to categorize findings on dynamic myelography based on the degree of diagnostic certainty was proposed. This was followed by a survey to patients and referring providers to evaluate the perceived value, clarity, and impact of SIH-RADS on patient and provider experiences as an adjunct to traditional reporting methods for dynamic myelography.
