1.5T动态增强核磁共振诊断鉴别前列腺癌价值研究

Clinical value of 1.5T dynamic enhanced MRI in the differential diagnosis of prostate cancer

目的分析1.5T动态增强核磁共振(MRI)在前列腺癌诊断鉴别中的临床应用价值。方法选取浙江衢化医院2017年1月至2017年12月收治的前列腺疾病患者298例作为研究对象,所有对象进行MRI检查[包括T2加权成像(T2WI)、扩散加权成像(DWI)、动态增强(DCE)],观察所有对象的检查结果,并以病理活检作为确诊金标准,对出现前列腺癌的可能性做出评价。结果在该次研究中所选择的298例前列腺疾病患者中共有前列腺癌136例,其中外周前列腺癌84例,T2WI、DWI、DCE检出率均为100.00%,中央腺体前列腺癌52例,T2WI、DWI、DCE检出率分别为100.00%、98.08%、98.08%;298例前列腺疾病患者中共有前例腺炎162例,其中外周前列腺炎64例,T2WI、DWI、DCE检出率分别为98.44%、100.00%、96.88%,中央腺体前例腺炎98例,T2WI、DWI、DCE检出率分别为97.96%、100.00%、98.98%。结论1.5T动态增强MRI能够准确的检出前列腺疾病,尤其是前列腺癌。

Objective To analyze the clinical value of 1.5T dynamic enhanced MRI in the differential diagnosis of prostate cancer. Methods A total of 298 patients with prostate disease admitted to Zhejiang Quhua Hospital from January 2017 to December 2017 were enrolled.All subjects underwent MRI(including T2WI, DWI, DCE), and the results of all subjects were observed.The pathological biopsy was used as the gold standard for diagnosis.The possibility of prostate cancer was evaluated. Results Among the 298 patients with prostate disease, there were 136 cases of prostate cancer, including 84 cases of peripheral prostate cancer, the detection rates of T2WI, DWI and DCE were all 100.00%, 52 cases of central gland prostate cancer, the detection rates of T2WI, DWI and DCE were 100.00%, 98.08%, and 98.08%, respectively.Among 298 patients with prostate disease, there were 162 cases of pre-existing adenitis, including 64 cases of peripheral prostatitis.The detection rates of T2WI, DWI and DCE were 98.44%, 100.00%, 96.88%, respectively, 98 cases of central glandular gland inflammation, the detection rates of T2WI, DWI, DCE were 97.96%, 100.00%, 98.98%, respectively. Conclusion 1.5T dynamic enhanced MRI can correctly detect prostate diseases, especially prostate cancer.
