DTI is a vital tool in many neurological applications. ssEPI is the method of choice in clinical DTI but suffers from strong geometric distortions. FSE and PROPELLER-based techniques are free from geometric distortions but have low scan efficiency. Recently, a split-blade turboPROP technique has been enhanced for brain DWI with improved image quality. In this work we develop a whole-blade acquisition mode and a blade sharing strategy with turboPROP for DTI at a speed comparable to an ssEPI-based clinical protocol. In vivo results demonstrate good image quality.
