Synopsis

Keywords: Prostate, Image Reconstruction, Deep learning reconstructionThe image quality of high-resolution PROPELLER T2WI combined with deep learning reconstruction (DLR) in prostate MRI was evaluated by the phantom and clinical studies. In the phantom study, noise reduction was achieved by DLR, and spatial resolution was remarkably improved in PROPELLER T2WI compared to Cartesian T2WI. In the clinical study, DLR showed a significant improvement in signal-to-noise ratio, and the qualitative analyses showed reduced image noise and improved spatial resolution, with PROPELLER T2WI DLR images showing the highest overall image quality. PROPELLER T2WI with DLR would be promising technique to improve the image quality of T2WI in prostate MRI.
