DWI suffers from problems of severe geometric distortion and artifacts due to the susceptibility gradients and long echo train length (ETL), and the spatial resolution is quite limited due to the single-shot EPI acquisition scheme. This study investigates the utility of a targeted-FOV (TFOV) DWI technique in characterizing acute renal injure caused by microemboli injection in animal models. Compared with full-FOV DWI, the TFOV DW images show apparently higher image quality and better depiction of renal lesions. The advantage of TFOV DWI technique in characterizing microemboli-induced acute renal injure in is quite obvious.
