T2* weighted imaging can be used to study both normal and pathological tissue. These images are commonly obtained using traditional gradient echo sequences which can lead to long scan times that are problematic particularly in a clinical setting. 3D EPI offers a faster alternative with scan times on the order of few minutes. Here, the scan time of T2* weighted 3D EPI scans is further reduced with a shot selective 2D CAIPI acquisition pattern. Whole brain T2* weighted anatomical scans with a resolution of 0.5 mm isotropic were acquired in 1:27 minutes. This holds promising perspectives for future applications in routine examinations.
