Zusammenfassung
Zielsetzung: Aim of this study was to measure blood flow in the descending aorta (AD) and azygos vein (Az) using Mueller maneuver (MM) as physiological stress test in real-time cardiac magnetic resonance imaging technique (RT-CMR) using a further development of established fast low-angle shot (FLASH) sequence with high temporal and spatial resolution. Material und Methodik: Blood flow was measured in n = 20 healthy volunteers in the AD and Az simultaneously with RT-CMR including an image acquisition of 40 ms and under-sampled radial FLASH. The volunteers were instructed to perform MM (“reversed” Valsalva maneuve…
