This study is to evaluate the clinical application of PROPELLER reconstruction technique to reduce breathing-induced motion artifacts in bladder imaging. High resolution T2W images were acquired with and without multivane (PROPELLER technique) in fourteen patient scans. Image quality was assessed by a radiologist in terms of motion artifacts and the visualization of tumor margins. Scores were given in the range of 1 to 4. The results showed that the application of multivane significantly improved both motion artifacts and tumor visualization (both P<0.001). In conclusion, PROPERLLER reconstruction is a robust technique to substantially reduce the artifacts caused by unavoidable breathing motion to provide the delineation of bladder tumors against surrounding tissues.
