摘要
目的:探讨磁共振全身弥散成像(WB-DWI)在前列腺癌(PCa)转移灶筛查中的应用。材料与方法:收集47例前列腺癌病例,均行全身弥散成像,结合病变部位常规MRI扫描;其中盆腔39例、全脊柱30例、胸部5例、中上腹部7例,取T1、T2加权像及压脂成像扫描。结果:本组病例筛查出骨盆转移33例,脊柱转移21例,双肺转移3例,肝脏转移2例,肾脏转移2例;骨盆、脊柱、双肺、肝脏均为多发转移,肾脏为单发转移。前列腺癌及转移灶在WB-DWI黑白反转图像上呈团块状、结节状、斑片状或斑点状低信号,T1WI呈稍低信号,T2WI/STIR呈稍高信号,肝脏转移灶增强后不规则环状强化。结论:全身弥散成像结合常规MRI扫描,对前列腺癌及转移灶能起到一站式检出诊断的作用。
Purpose： Investigate application of whole body diffusion weight imaging（WB-DWI） in detection prostate cancer（PCa） metastasis. Materials and Methods： 47 cases of Pea were collected, all cases underwent WB-DWI , com- bine with conventional MRI scan in lesions. The pelvic cavity （ 39 cases）, spinal （ 30 cases）, Thoracic （5 cases）, abdo- men （ 7 cases） ; take T1 , T： weighted imaging and fat-suppressed imaging scan. Results： In the group of cases detected pel- vic metastasis （33 cases）, spinal metastasis （ 21 cases）, lung metastasis （ 3 cases）, liver metastasis （ 2 cases）, renal me- tastases （ 2 cases） ; pelvis, spine, lung and liver were mutiple metastases, kidney is solitary metastasis. PCa of the prostate and metastasis in the WB-DWI inversion image is mass, nodular, patchy or mottled low signal, T1WI showed slightly low sig- nal, slightly high signal of T2WL/STIR, hepatic metastasis after enhancement show irregular ring-like enhancement. Conclu- sion： Whole body diffusion weight imaging combine conventional MRI scan, can play one station type detection and diagnosis function in PCa of the prostate and metastasis.
