摘　　要：磁共振成像是诊断早期前列腺癌及评价分期最好的影像学技术之一,然而常规MRI-T2WI在诊断中存在较低的特异性缺陷。随着核磁技术的发展,对前列腺癌的诊断发展到从定性到定量、从形态到功能的变化,本文主要就近年来的磁共振功能成像技术在前列腺癌诊断中的研究进展作一论述。Magnetic resonance imaging is accepted as one of the best imaging modalities for detecting and staging prostate cancer. Generally, T2-weighted imaging has been used for this purpose. However, the diagnostic accuracy of conventional T2WI has its own disadvantages such as low specificity. With the development of imaging technique, its has changed from qualitations to quantitations,and appearance to functions to diagnose the prostate cancer. This article gives a review on progression of the functional MRI to diagnose the prostate cancer.
