目的:探讨MRI诊断前列腺疾病的价值。材料与方法:回顾分析我院2008-10—2110-12收集49例前列腺疾病患者临床资料及MRI所见,其中前列腺癌(PCa)22例、前列腺增生(BPH)16例、前列腺炎8例、前列腺囊肿2例、前列腺肉瘤1例。结果:22例Pca患者14例发生于外周带,3例发生于中央带,病变范围广泛,分界不清5例;所见22例前列腺不规则增大19例,前列腺经线在正常范围3例;病变均表现为低信号或低混杂信号,边界不清,无包膜,侵犯邻近组织或远处转移。16例BPH患者11例发生于移行带,4例位于中央带,表现为移行带及中央叶体积增大,信号混杂,均有完整或不完整包膜;发生于外周带1例,表现为低信号结节。前列腺炎5例前列腺弥漫性肿大,3例发生于外周带,表现为斑片状模糊T2WI异常稍低信号影。前列腺囊肿2例主要位于精阜区域和射精管走行区,均匀囊性结构,T1WI低信号,T2WI高信号。前列腺肉瘤1例,前列腺体积明显增大,以中央叶增大为著,T1WI呈不均质性低信号,T2WI呈中心高新号、外周稍高信号的混杂信号。结论:MRI是诊断前列腺疾病较有效的检查方法。
Objective: To explore the value of MRI in the diagnosis of prostate diseases. Materials and Methods: A retrospective analysis of our hospital 2008-10-2110-12 Collection of 49 cases of prostate disease in patients with clinical data and MRI, including 22 cases of prostate cancer (PCa), 16 cases of benign prostatic hyperplasia (BPH), 8 cases of prostatitis, Prostate cyst in 2 cases, 1 case of prostate sarcoma. Results: Of the 22 patients with Pca, 14 cases occurred in the peripheral zone and 3 cases occurred in the central zone. The lesions ranged widely with 5 cases of unclear boundaries. Twenty-two of the 22 cases of irregular prostate enlargement, 19 cases of normal prostate gland, Lesions were manifested as low signal or low mixed signal, the boundary is unclear, no capsule, invasion of neighboring tissues or distant metastasis. Of the 16 BPH patients, 11 cases occurred in the transition zone and 4 in the central zone, which showed the enlargement of the transitional zone and the central lobe, the mixed signal, and the incomplete or incomplete envelope. One case occurred in the peripheral zone with low Signal nodules. Prostatitis in 5 cases of diffuse enlargement of the prostate, 3 cases occurred in the peripheral zone, manifested as patchy fuzzy T2WI abnormally lower signal. Prostate cysts in 2 cases were mainly located in the Jing Fu area and ejaculatory duct walking area, uniform cystic structure, T1WI low signal, T2WI high signal. Prostate sarcoma in 1 case, the prostate volume was significantly increased to increase the central lobe is, T1WI showed a heterogeneous low signal, T2WI was high-center number, slightly higher signal of the peripheral mixed signal. Conclusion: MRI is a more effective method for the diagnosis of prostate disease.
