Purpose : The purpose of the study was to evaluate the feasibility and the clinical application of additional view-sharing for 4D contrast-enhanced MR angiography (CEMRA) at 3.0T. Methods: 4D CEMRA of the head with randomly segmented central k-space ordering (CENTRA), keyhole, parallel imaging (SENSE) and view sharing with a compression factor of 80% was performed in 7 volunteers and 4 patients on a clinical whole body 3.0T MR system (Achieva X series, Philips Medical Systems, Best, NL) using an 8-element head coil (Philips Medical Systems, Best, NL). DSA correlation was available in 2 patients with cerebral art…
