Image quality of T2WI suffers from long scanning time. Compressed SENSE (C-SENSE) allow for Shorter scanning time and Ensuring good image quality，Image quality can be further optimized with CSAI . A total of 20 patients with prostate cancer (PC) underwent MRI including T2WI with SENSE-2（S2）and SENSE-4 （S4）、CS4 and CSAI4. SNR was significantly higher in CSAI4 than CS4 and S4. In comparison CNR between of S4、CS4 and CSAI4 of clinically insignificant PC, only CSAI4 had significant difference. CSAI4 improves the image quality and may contribute to increased diagnostic performance of tumor and clinicians’ confidence in the detection and diagnosis of prostate cancer.
