Purpose: To evaluate high spatial resolution intracranial 3D time-of-flight (TOF) MR angiography at 3.0T using Sensitivity Encoding (SENSE). Methods: In a prospective study TOF MR angiography of the circle of Willis was performed with SENSE in 24 patients on a clinical whole body 3.0T MR system (Intera, Philips Medical Systems, NL). In the SENSE protocol (S-MRA), a SENSE factor of 2.5 was used to shorten acquisition time and to increase the anatomic coverage (5:12min.; 150 slices). A matrix of 832×572 was acquired and reconstructed to 1024 yielding a non-zerofilled voxel size of 0.30×0.44×1.00 mm3 (0.13 mm3). Im…
