Current Concepts of Cerebrovascular Disease and Stroke Magnetic Resonance Angiography Cerebrovascular Applications
Magnetic resonance angiography (MRA) can provide significant additional information to complement the routine spin-echo MR examination of the brain." The idea of a combined study has gained favor because it provides a noninvasive alternative for the complete study of patients with suspected cerebrovascular disease. Because of the relatively short time of acquisition, MRA sequences can be easify...

متن کاملCoronary magnetic resonance angiography.
Coronary magnetic resonance angiography (MRA) is a powerful noninvasive technique with high soft-tissue contrast for the visualization of the coronary anatomy without X-ray exposure. Due to the small dimensions and tortuous nature of the coronary arteries, a high spatial resolution and sufficient volumetric coverage have to be obtained. However, this necessitates scanning times that are typical...

68 Introduction MR Imaging (MRI) depends on relaxation times T1 and T2 and spin density r. Furthermore, MRI is very sensitive to motion resulting in a variety of flow effects. On one hand, flow effects are responsible for a number of artifacts which can drastically impair the diagnostic value of the images; on the other hand, flow effects can be used advantageously to develop non-invasive techn...
