To investigate the efficacy of the radial acquisition regime (RADAR) for acquiring head and neck MR images.15 healthy volunteers underwent imaging with 4 sequences [fast spin echo TRegardless of mouth motion, RADAR-T2WI was significantly superior to FSE-T2WI in artefacts and oral-area detectability (p<0.01), and RADAR-DWI was significantly superior to SS-EPI-DWI in terms of artefacts (p<0.01). In terms of image distortion, RADAR-DWI was significantly superior to SS-EPI-DWI (p<0.01).RADAR-T2WI could replace FSE-T2WI as a conventional T2WI protocol for the head and neck. For the RADAR-DWI sequence, validation studies are needed. Advances in knowledge: RADAR-T2WI was superior to FSE-T2WI with regard to artefacts and detectability, and RADAR-DWI was superior in terms of artefacts compared with SS-EPI-DWI.
