- Pulsatile Tinnitus Due to Stenosis of the Marginal Sinus: Diagnosis and Endovascular Treatment
Marginal sinus stenosis is a novel cause of venous pulsatile tinnitus, which can be easily detected on MR imaging. Marginal sinus stent placement is safe and efficient.
- Prenatal Evaluation of Intracranial Hemorrhage on Fetal MRI: A Retrospective Review
The EPI blood sequence is the most sensitive in the identification of fetal intracranial hemorrhage, which, in conjunction with T2-SSFSE images, can optimize classification and subsequent grading of germinal matrix hemorrhages in the fetus. The authors report a significant increase in neonatal death in the non-GMH-versus-GMH group and worsened brain parenchymal findings in more severe GMH grades (III-IV) on postnatal MR imaging.
- Clinical Implementation of 7T MRI for the Identification of Incidental Intracranial Aneurysms versus Anatomic Variants
In 30 cases, the differentiation of an aneurysm versus a vascular variant could be achieved. In 20 cases (66%), the initial suspected diagnosis was revised. The findings suggest that 7T MR imaging provides a clarification tool for the group of patients with suspected unruptured intracranial aneurysms and diagnostic ambiguity after standard 3T MR imaging.
- Changes in Ventricular and Cortical Volumes following Shunt Placement in Patients with Idiopathic Normal Pressure Hydrocephalus
Overall, cortical volumes mildly increased after shunt placement in patients with idiopathic normal pressure hydrocephalus with the greatest increases in regions near the vertex, indicating postshunt decompression of the cortex and sulci.
