DSA was used to study patients with Moyamoya disease with acute stroke. Advanced Suzuki angiographic stages, aneurysms, arterial occlusions, and collateral flow including transdural anastomoses were present more often in patients with hemorrhage than in those with only ischemia. These findings are the main contributors to the development of hemorrhagic strokes in patients with Moyamoya disease.

The authors evaluated radiologists' current reporting practices for incidental thyroid nodules detected on CT and MRI. The most common responses to the survey were to recommend sonography and to report the nodules only in the body of the report. No significant differences were found when years of practice, practice types, and subspecialty were examined. Reporting practices were especially variable for patients with smaller nodules (≤10 mm) and those with multiple nodules and a history of cancer.

Patients with MS and healthy controls underwent catheter venography to study whether stenoses and/or insufficiency affecting the azygous and internal jugular veins were related to the disease. There were no differences in the presence of stenoses and/or chronic cerebrospinal venous insufficiency between the 2 groups and thus the authors state that their data exclude a direct correlation between these anomalies and MS.

Patients studied for acute stroke were evaluated with full- and half-dose contrast-enhanced neck MRA and brain perfusion imaging and results were compared. Detection specificity and overestimation of stenoses were slightly higher for the half-dose studies but perfusion mismatches were identified with high interobserver agreement at both doses. Thus, low-dose studies are feasible and save time and contrast volume.
