Robust dynamic contrast-enhanced T1-weighted images are crucial for accurate detection and categorization of focal liver lesions in liver/abdominal magnetic resonance imaging (MRI). As optimal dynamic imaging usually requires multiple breath-holds, i

3D Motion Adapted Gating: Eine neue Navigatortechnik zur Verkürzung der Messzeit bei der MR-Koronarangiographie

Autor: Kay Nehrke, H. H. Schild, K Tiemann, A Yang, Jürgen Gieseke, Torsten Sommer, C. Schmitz, M Hackenbroch, Carsten H. Meyer, Gabriele M. Beck

Publikováno v: RöFo - Fortschritte auf dem Gebiet der Röntgenstrahlen und der bildgebenden Verfahren. 177:350-357

PURPOSE: A major problem of free breathing coronary MR angiography (MRA) with respiratory navigator gating is low navigator efficiency and prolonged scan time due to irregular breathing patterns. 3D motion adapted gating (MAG) is a new adaptive navig

Reducing oblique flow effects in interleaved EPI with a centric reordering technique

Autor: Gabriele M. Beck, E. Mark Haacke, Lothar R. Schad, Tobias G. Noll, Debiao Li

Publikováno v: Magnetic Resonance in Medicine. 45:623-629

Segmented interleaved echo planar imaging offers a fast and efficient approach to magnetic resonance angiography. Unfortunately, this technique is particularly sensitive to oblique flow in the imaging plane. In this work, a mathematical analysis of o
