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...
متن کاملMagnetic Resonance Angiography Techniques
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...
متن کاملWhole body magnetic resonance angiography and computed tomography angiography in the vascular mapping of head and neck: an intraindividual comparison
INTRODUCTION The aim of the study was to compare the detectability of neck vessels with contrast enhanced magnetic resonance angiography (MRA) in the setting of a whole-body MRA and multislice computed tomography angiography (CTA) for preoperative vascular mapping of head and neck. METHODS In 20 patients MRA was performed prior to microvascular reconstruction of the mandible with osteomyocuta...
