In PROPELLER imaging, multiple blades are acquired in k-space and rotated around the center to cover all of k-space. This has proven useful to mitigate motion artifacts in Cartesian FSE. In this work, a new pulse sequence called Image domain Propeller FSE (iProp-FSE) is proposed as an alternative for T2-w imaging, having propeller blades in the image domain instead of k-space. Similar to PROPELLER, motion correction can be performed between the blades. Moreover, the averaging effect of all blades in the center of the image FOV increases the SNR locally, which is especially useful for multi-channel head coils.
