前列腺外周带ADC值测量在前列腺癌诊断中的应用

Application of prostatic peripheral zone ADC value measurement in diagnosis of prostate cancer

目的:探讨ADC测量在前列腺癌诊断和鉴别诊断中的应用价值。方法:收集前列腺癌和前列腺炎患者各43病例资料,分析其常规MRI表现,并分别测量病变区的ADC值,求取平均值,统计分析二者之间的差别。结果:43例前列腺癌患者中,局灶性病变31例,弥漫性病变12例,ADC值平均值为923±110.4;43例前列腺炎患者中,局灶性病变20例,弥漫性病变23例,ADC值平均值为811±102.6。两组间ADC值平均值比较,P值小于0.05,差别具有统计学意义。结论:在前列腺癌早期诊断和鉴别诊断中,对ADC值的测量具有重要价值。

Objective：To investigate application value of ADC measurement in diagnosis and differential diagnosis of prostate cancer. Methods：The data of 43 cases with prostate cancer and 43 cases with prostatitis were collected. The conventional MRI was analyzed. The ADC values in the lesion area were measured,and their average values were calculated. The differences between prostate cancer and prostatitis were statistically analyzed. Results： In the 43 cases with prostate cancer,31 patients had focal lesions,12 cases had diffuse lesions,and the average ADC value was 923 ± 110. 4; however,in the 43 cases with prostatitis,20 cases had focal lesion,23 cases had diffuse lesions,and the average ADC value was 811 ± 102. 6. Between the two groups,the difference of the ADC average values had a statistical significance（P〈0. 05）. Conclusions： The ADC value measurement is an important supplement to the conventional MRI,and provides the early diagnosis and differential diagnosis for prostate cancer.
