An in-house developed multi-contrast EPI sequence producing six MR contrasts (T1-FLAIR, T2-w, DWI, ADC, T2*-w, and T2-FLAIR) was used as a fast brain MRI protocol. Seven healthy volunteers were scanned repeatedly to investigate how many brain MRI exams that can be performed over the course of one hour. With a net scan time of one minute and an additional minute for table movements and switch of subjects, it was possible to perform 30 brain MRI examinations in 1 h.
