摘　　要：目的探讨多参数MRI对外周带早期前列腺良恶性病变的诊断效果。方法选取我院接受治疗的52例前列腺疾病患者进行多参数MRI影像检测,比较其多参数MRI影像中的多项指标。结果 MRI诊断前列腺增生敏感性为93.5%,MRI诊断前列腺癌的敏感性为91.3%。前列腺癌组中央线体以及外周带的ADC值分别为(0.6913±0.1123)×10-3mm2/s)和(0.6426±0.1213)×10-3mm2/s)皆低于前列腺增生患者中央线体和外周带的ADC值,差异具有统计学意义。统计分析所有患者的MRI表现,在前列腺增生的患者中,外周带增生3例,中央带增生患者29例,外周带增生患者在MRI图像中结节可见、边界明显、包膜完整,中央带增生患者在MRI图像中中央带明显增大,外周带变薄,内外信号不均。前列腺癌患者中,位于中央带的患者1例,占总比例的4.7%,位于外周带的患者15例,占总比例的71.4%。各项指标比较(P<0.05),结果均具有差异性。结论使用多参数MRI影像能够准确地检测前列腺疾病及病灶特点。Objective To explore the effect of multi-parameter MRI on the diagnosis of benign and malignant benign prostatic lesions in the peripheral zone. Methods 52 patients with prostate disease who were treated in our hospital and the first people＇s Hospital of Kunshan from April 2017 to April 2017 were retrospectively analyzed,including 21 patients with prostate cancer and31 patients with benign prostatic hyperplasia. All patients were diagnosed by clinical diagnosis,surgical pathology or biopsy. All patients were diagnosed by clinical diagnosis,surgery and pathology or biopsy. In 52 cases of prostate disease patients underwent multi parameter MRI image detection,the multi parameter MRI image in the location,size,shape,signal and ADC lesions（ 10-3mm2/s） value index,diagnosis and analysis of results. Results MRI diagnosis of benign prostatic hyperplasia sensitivity was93. 5%,MRI diagnosis of prostate cancer sensitivity was 91. 3%. The ADC values of the central line and the peripheral zone of the prostate cancer group were（ 0. 691 3 ± 0. 112 3） × 10-3mm2/s） and（ 0. 642 6 ± 0. 121 3） × 10-3mm2/s）,respectively,which were lower than those of the benign prostatic hyperplasia patients and the peripheral ADC values,the difference was statistically significant. Statistical analysis of all patients with MRI performance in patients with benign prostatic hyperplasia,peripheral hyperplasia in 3 cases,29 cases of central hyperplasia in patients with peripheral hyperplasia in the MRI images of nodules visible,the border was clear,complete capsule,central zone hyperplasia the central area of the patient was significantly increased in the MRI image,the peripheral zone was thinner,and the internal and external signals were not uniform. In patients with prostate cancer,there were 1 patient in the central zone,accounting for 4. 7% of the total,15 patients in the peripheral zone,accounting for 71. 4% of the total. Of the indicators（ P〈0. 05）,the results are different. Conclusion The use of multi parameter MRI im
