摘　　要：目的分析3.0T磁共振弥散加权成像对前列腺癌的诊断价值。方法选取2020年1月至2024年3月在北京市垂杨柳医院进行前列腺检查的168例患者作为研究对象,所有患者均给予3.0T磁共振弥散加权成像检查。比较研究对象的MRI信号特征状况与表观扩散系数(ADC);以手术病理检查结果作为金标准,分析3.0T磁共振弥散加权成像诊断前列腺癌的灵敏度、特异度与准确度。结果经手术病理检查,168例患者中有68例确诊为前列腺癌,归入前列腺癌组;其余100例被诊断为前列腺增生,归入前列腺增生组。前列腺癌组的MRI信号特征多为低信号,前列腺增生组多为高信号。两组的MRI信号特征比较,差异具有统计学意义(P<0.05)。当b值为500、1000 s/mm^(2)时,前列腺增生组的ADC值明显高于前列腺癌组,差异具有统计学意义(P<0.05)。3.0T磁共振弥散加权成像对前列腺癌的诊断灵敏度、特异度、准确度分别为97.06%、99.00%、98.21%。结论前列腺癌患者在3.0T磁共振弥散加权成像中多表现为低ADC与低信号,3.0T磁共振弥散加权成像对前列腺癌具有较高的诊断价值。Objective To analyze the diagnostic value of 3.0T magnetic resonance diffusion weighted imaging in prostate cancer.Methods A total of 168 patients who underwent prostate examination in Beijing Chuiyangliu Hospital from January 2020 to March 2024 were selected as the research objects.All patients were given 3.0T magnetic resonance diffusion weighted imaging examination.The MRI signal characteristics and apparent diffusion coefficient(ADC)of the objects were compared.The sensitivity,specificity and accuracy of 3.0T magnetic resonance diffusion weighted imaging in the diagnosis of prostate cancer were analyzed by using the results of surgical pathological examination as the gold standard.Results After surgical pathological examination,68 case of the 168 patients were diagnosed with prostate cancer and classified at prostate cancer group,and the remaining 100 case were diagnosed with benign prostatic hyperplasia,classified as benign prostatic hyperplasia group.The MRI signal characteristics of the prostate cancer group were mostly low signal,and the prostate hyperplasia group was mostly high signal.The difference of MRI signal characteristics between the two groups was statistically significant(P<0.05).When the b value was 500,1000 s/mm^(2),the ADC value of the benign prostatic hyperplasia group was significantly higher than that of the prostate cancer group,and the difference was statistically significant(P<0.05).The sensitivity,specificity and accuracy of 3.0T magnetic resonance diffusion weighted imaging in the diagnosis of prostate cancer were 97.06%,99.00%and 98.21%,respectively.Conclusion Patients with prostate cancer often show low ADC and low signal in 3.0T magnetic resonance diffusion weighted imaging.3.0T magnetic resonance diffusion weighted imaging has higher diagnostic value for prostate cancer.
