BACKGROUND AND PURPOSE Carotid intraplaque hemorrhage is associated with stroke, plaque thickness, stenosis, ulceration, and adventitial inflammation. Conflicting data exist on whether calcification is a marker of plaque instability, and no data exist on adventitial calcification. Our goal was to determine whether adventitial calcification and soft plaque(More)
PURPOSE Carotid artery imaging is important in the clinical management of patients at risk for stroke. Carotid intraplaque hemorrhage (IPH) presents an important diagnostic challenge. 3D magnetization prepared rapid acquisition gradient echo (MPRAGE) has been shown to accurately image carotid IPH; however, this sequence can be limited due to motion- and(More)
BACKGROUND AND PURPOSE MR imaging-detected carotid intraplaque hemorrhage indicates vulnerable plaque with high stroke risk. Angiotensin II stimulates intraplaque hemorrhage in animal models, and the angiotensin system is highly regulated by vitamin D. Our purpose was to determine whether low vitamin D levels predict carotid intraplaque hemorrhage in(More)
BACKGROUND Obesity has been associated with worse outcomes and increased surgical technical difficulty. Perinephric fat (PNF) and periumbilical fat (PUF) are alternative metrics to body mass index. We hypothesized that PUF and PNF would offer improved prediction of perioperative risk. METHODS 249 patients were retrospectively reviewed after elective,(More)
