From: A whole-body Fast Field-Cycling scanner for clinical molecular imaging studies
Transverse images of the brain of a patient diagnosed with vasculitis. The top images are from a 3 T MRI scanner (Achieva, Philips, Netherlands) using T2-weighted (a) and diffusion-weighted (b) sequences. The bottom line shows images from FFC-MRI, either magnitude images at 200 mT and 455 ms evolution field and time (c) or at 6.9 mT and 196 ms evolution field and time (d). These show large changes in the T1 values between these fields, with the lesion showing longer T1 relative to other tissues at lower fields. (e) shows a composite image regrouping the T1 images at three different fields (200, 6.9 and 1.3 mT).
