前列腺癌是世界上第二常见的男性恶性肿瘤,我国前列腺癌的发病率亦呈逐年上升趋势.MRI有着良好的软组织分辨率及多方位成像优势,能较好地显示前列腺的解剖结构及相邻的组织结构,随着MRI技术的不断发展,其对前列腺癌的诊断发挥着越来越重要的作用.该文从前列腺癌MRI常规序列的影像表现着手,对各种功能MRI在前列腺癌的诊断和鉴别诊断中的应用进行了详细地论述,如MR灌注加权成像、MR波谱、MR扩散加权成像、MR扩散张量成像、体素内不相干运动扩散加权成像、MR磁敏感加权成像等,介绍了功能MRI相对于常规扫描的优势及其所能提供的更多的影像学资料,通过系列半定量和定量数据,能进一步提供前列腺癌的血流灌注、水分子扩散、微循环状态、物质代谢及生化成分变化等信息.
前列腺癌是世界上第二常見的男性噁性腫瘤,我國前列腺癌的髮病率亦呈逐年上升趨勢.MRI有著良好的軟組織分辨率及多方位成像優勢,能較好地顯示前列腺的解剖結構及相鄰的組織結構,隨著MRI技術的不斷髮展,其對前列腺癌的診斷髮揮著越來越重要的作用.該文從前列腺癌MRI常規序列的影像錶現著手,對各種功能MRI在前列腺癌的診斷和鑒彆診斷中的應用進行瞭詳細地論述,如MR灌註加權成像、MR波譜、MR擴散加權成像、MR擴散張量成像、體素內不相榦運動擴散加權成像、MR磁敏感加權成像等,介紹瞭功能MRI相對于常規掃描的優勢及其所能提供的更多的影像學資料,通過繫列半定量和定量數據,能進一步提供前列腺癌的血流灌註、水分子擴散、微循環狀態、物質代謝及生化成分變化等信息.

Prostate cancer is the second most common cancer in the world,and the incidence of prostate cancer in China shows an upward trend.MRI has high soft tissue resolution and mnulti-dimensional imaging advantages,and it can better show the anatomy of the prostate and adjacent tissue structures.With the development of MR technique,it plays a more and more important role in prostate cancer diagnosis.This review starts from the imaging performance of routine MRI sequence of prostate cancer,and a variety of functional MRI applications in the diagnosis and differential diagnosis of prostate cancer are described in detail,such as MR perfusion-weighted imaging,MR spectroscopy,MR diffusion-weighted imaging,MR diffusion tensor imaging,intravoxel incoherent motion diffusion-weighted imaging,MR susceptibility-weighted imaging.Meanwhile this review introduces that functional MRI has more advantages and can provide more image information than routine MRI sequence.According to a series of semi-quantitative and quantitative data,functional MRI can further provide the blood perfusion of prostate cancer,water molecule diffusion and microcirculation state,metabolism and biochemical composition change information.
