Assessing the Impact of Caring for a Person with Schizophrenia: Development of the Schizophrenia Caregiver Questionnaire
Four-D blood flow patterns in the thoracic aorta in patients with CAD compared to age-matched normal subjects
Magnetic Resonance Angiography Four-Dimensional Aortic Blood Flow Patterns in Thoracic Aortic Grafts
Time-resolved cardiac gated three-directional velocity data obtained with magnetic resonance velocity-encoded phase contrast sequences were used to study bloodflow patterns in thoracic aortic grafts. Twelve patients were studied, 6 with traumatic descending aortic pseudoaneurysms, 3 with atherosclerotic aneurysms, and 3 with dissecting aneurysms. All grafs had an inflow jet; outflow jet; and/or vortices proximal, in, or distal to the graf. Flow abnormalities were generally mild in the descending aortic traumatic pseudoaneurysms seen in young people. The atherosclerotic aneurysms seen in elderly patients had the most abnormal flows with multiple vortices in and outside the graft. Blood persisted up to one and a half heartbeats in some vortices and took three to five heartbeats to ow patterns; Traumatic descending aortic pseudoaneurysm
