- An Optimized CT Protocol for Detecting Suspected Cauda Equina Syndrome: A Comparative Analysis with MRI
This study prospectively evaluated the diagnostic accuracy of an optimized CT lumbar spine protocol as a potential alternative to MRI in assessing suspected neural compression. CT accurately identified all cases requiring urgent decompression. CT had 97% sensitivity, specificity, and positive and negative predictive values in detecting disc pathology in patients presenting with symptoms suggestive of acute neural compression compared with MRI.
- Risk of Hemorrhagic Transformation after Mechanical Thrombectomy without versus with IV Thrombolysis for Acute Ischemic Stroke: A Systematic Review and Meta-analysis of Randomized Clinical Trials
This systematic review and meta-analysis evaluated the risk of intracerebral hemorrhage, and its subtypes associated with mechanical thrombectomy with or without IV thrombolysis for the treatment of acute ischemic stroke due to large-vessel occlusion. The analysis showed that the overall risk of symptomatic intracerebral hemorrhage was comparable between mechanical thrombectomy with IV thrombolysis and mechanical thrombectomy alone.
- Retrolabyrinthine Bone Thickness as a Radiologic Marker for the Hypoplastic Endotype in Menière Disease
There are 2 major endotypes of Menière disease: one with a hypoplastic, underdeveloped endolymphatic sac and one with a normally developed sac that degenerates over time. This study explored the link between angular trajectory of the vestibular aqueduct and the thickness of the retrolabyrinthine bone to provide differentiation between MD endotypes using CT and MRI. The average retrolabyrinthine bone thickness was statistically significantly different between endotypes with retrolabyrinthine bone thickness >=1.2 mm, effectively ruling out hypoplastic Menière disease.
- Low-Field Portable MR Imaging to Evaluate Ventricular Volumes: A Single-Center Retrospective Study
The authors compared low-field portable and standard MR images of ventricular volume in the same pediatric patient. They showed high correlation in the estimates of ventricular volume between the 2 types of MR imaging, without systemic bias.
