摘　　要：目的观察良性前列腺增生与前列腺癌MSCT征象,分析MSCT对前列腺疾病的鉴别诊断价值。方法选取了我院2017年6月至2018年12月收治的良性前列腺增生、前列腺肿瘤患者各53例,收集患者临床资料及影像学资料,总结MSCT图像特征,计算MSCT对良性前列腺增生、前列腺癌的鉴别诊断效能。结果MSCT对良性前列腺增生诊断正确率为98.11%(52/53),MSCT对前列腺癌诊断正确率为92.45%(49/53),与临床检查结果对比,MSCT对良性前列腺增生、前列腺癌的诊断正确率无明显差异(P>0.05)。前列腺癌患者病灶外形呈结节状或片状,平扫显示均匀软组织密度影,膀胱壁出现不规则增厚,膀胱精囊三角区域基本消失,同时与膀胱界限模糊,增强动脉期及静脉期扫描均可见强化均匀,良性前列腺增生和前列腺癌的最大强化幅值分别为(45.12±10.01)HU、(45.42±9.74)HU,并未见明显差异(P>0.05)。前列腺癌以Ⅱ型和Ⅲ型为主,良性前列腺增生的强化曲线以I型为主,良性前列腺增生增强后可见增生的中央腺体和低密度外周带。结论MSCT可有效显示良性前列腺增生、前列腺肿瘤的影像学表现,可有效鉴别诊断良性前列腺增生及前列腺癌,值得临床推广。Objective To observe the MSCT signs of benign prostatic hyperplasia and prostate cancer, and to analyze the differential diagnosis value of MSCT for prostate diseases. Methods 53 cases with benign prostatic hyperplasia and 53 cases with prostate cancer admitted to our hospital from June 2017 to December 2018 were selected. Clinical data and imaging data were collected. The characteristics of MSCT images were summarized. The efficacy of differential diagnosis of MSCT for benign prostatic hyperplasia and prostate cancer was calculated. Results The diagnostic accuracy of MSCT for benign prostatic hyperplasia was 98.11%(52/53), and the diagnostic accuracy of MSCT for prostate cancer was 92.45%(49/53). Compared with results of clinical examination, there was no significant difference in the diagnostic accuracy between MSCT and results of clinical examination for benign prostatic hyperplasia and prostate cancer(P>0.05). The lesions of patients with prostate cancer were nodular or flaky. The plain scan showed uniform soft tissue density, the bladder wall showed irregular thickening, and thetriangular domain between the seminal vesicle and the bladder disappeared. At the same time, the boundary between the bladder and the seminal vesicle was blurred. In the arterial phase and venous phase, the enhanced scan showed uniform enhancement. The maximum enhancement amplitude of benign prostatic hyperplasia and prostate cancer in this group were(45.12±10.01) HU and(45.42±9.74) HU, respectively, and no significant difference was observed(P>0.05). Prostate cancer was mainly type Ⅱ and type Ⅲ. The enhancement curve of benign prostatic hyperplasia was mainly type I. After the enhancement of benign prostatic hyperplasia, a hyperplastic central gland and peripheral zone with low-density can be seen. Conclusion MSCT can effectively display the imaging features of benign prostatic hyperplasia and prostate cancer, and can effectively differentiate and diagnose benign prostatic hyperplasia and prostate cancer, which is worthy of cli
