摘要
目的:通过对前列腺中央带及外周带ADC值分析,研究其在前列腺癌和非癌组织中的诊断价值。方法:对43例前列腺疾病分类,分为增生组和癌变组,并选取正常对照组,b=1 500 s/mm2。并对正常组、增生组和癌变组的ADC值进行统计学分析。结果:GE3.0T扩散加权成像技术高b值得出的前列腺癌变的ADC值明显低于正常和增生的ADC值,其间比较差异有统计学意义;前列腺中央带和外周带癌变的ADC值差异无统计学意义。结论:GE3.0T扩散加权成像选用高b值得出的ADC值分析结果表明前列腺癌和非癌组织有明显差异,更助于诊断前列腺癌。
Objective: Through the central zone of the prostate peripheral zone and the ADC value analysis,research in prostate cancer and non cancer diagnosis.Methods: 43 cases of prostate disease classification,divided into two groups and the proliferation of cancer group,and selected the normal control group,b=1 500 s/mm2.And the normal group,hyperplasia group and cancer group,ADC values were analyzed statistically.Results: GE3.0T high-b diffusion-weighted imaging of prostate cancer worth the ADC was significantly lower than ADC values of normal and proliferation,during which there was significant difference;prostate central zone and peripheral zone cancer was no significant difference between ADC values.Conclusion: GE3.0T high-b diffusion-weighted imaging should be selected out of analysis showed that ADC values of prostate cancer and non-cancer tissues are significantly different,but also help to diagnose prostate cancer.
