发明名称 SEGMENTED ACCELERATION-ENCODED CINE MRI
摘要 Conventional gradient echo sequences with relatively long echo-times visualise complex flow as signal loss, the degree and extent of which is a qualitative indicator of valvular heart disease. Since the long echo-time precludes segmentation, breath-hold imaging is not possible and acquisitions typically take 2-minutes with respiratory motion artefact being a frequent problem. In the present invention, a segmented sequence is used which generates similar degrees of signal loss to a conventional gradient echo sequence. However, the acquisition duration is reduced and breath-hold imaging is feasible, removing respiratory motion artefact.
