1.5T MR动态增强、扩散成像在前列腺癌诊断中的应用

Application of 1.5T MR dynamic enhancement and diffusion imaging in diagnosis of prostate cancer

目的探讨1. 5T MR动态增强、扩散成像在前列腺癌诊断中的应用。方法选取2016年6月至2018年6月80例前列腺癌患者作为研究组,另选取同期接受治疗的80例非前列腺癌患者作为参照组。两组患者均接受1. 5T MR动态增强技术和扩散成像技术进行检查,对两组检查的结果进行分析和比较。结果在0、60、120、180 s时间点的MR动态增强检查结果方面,研究组信号强度高于参照组,差异有统计学意义(P <0. 05);在b=0、150、300、500 s/mm2四个b值水平的MR扩散成像检查结果方面,研究组低于参照组,差异有统计学意义(P <0. 05)。结论在前列腺癌的诊断中,采用1. 5T MR动态增强技术和扩散成像技术进行诊断检查,效果明显,具有较高的诊断准确率,值得临床推广使用。

Objective To investigate the application of 1.5 T MR dynamic enhancement anddiffusion imaging in diagnosis of prostate cancer.Methods Eighty cases of prostate cancer from June2016 to June 2018 were selected as the research group,eighty cases of non-prostate cancer at the sametime were selected as the reference group.Both of the two groups took inspection with 1.5 T MR dynamicenhancement and diffusion imaging,and the results of inspection was analyzed and compared.Results At the 0,60,120,180 s time point,the signal strength of the research group were obviouslyhigher than those of the reference group in terms of the result of MR dynamic enhancement,and thedifferences were significant(P<0.05).The MR diffusion imaging test results,when the b=0、150、300、500 s/mm2,were lower of the research group than those of the reference group,and the differences weresignificant(P<0.05).Conclusions In the diagnosis of prostate cancer,the effect of 1.5 T MRdynamic enhancement and diffusion imaging for diagnostic examination,is obviouse,and the diagnosticaccuracy is high,which is worth clinical promotion.
