Purpose: To evaluate feasibility of dynamic, high spatial resolution contrast-enhanced (CE) MR angiography at 3.0T using CENTRA keyhole and sensitivity encoding (SENSE). Methods: In a prospective study, CE MRA of the brain (n=6) and the feet/hand (n=2) was performed with CENTRA keyhole and SENSE in 8 patients on a clinical whole body 3.0T MR system (Intera, Philips Medical Systems, NL). SENSE factors of 3 and 2 were used in phase encoding and slice encoding direction, respectively (T1w 3D gradient-echo; TR/TE/FA, 2.9–4.4 msec/1.0–1.4 msec/25°). With a keyhole diameter of 16%, 29 (brain) and 6 Feet/hand) dynamic…
