Magnetic Resonance Imaging of 20 patients with local prostatic carcinoma was correlated with pathological findings after radical prostatectomy. The tumor was always seen with an hyposignal, associated in 6 cases with benign prostatic hyperplasia. Extracapsular extension was correctly evaluated (17 cases/20). There were 6 false positive diagnosis of seminal vesicles extension among 40 cases because of an hyposignal in intact vesicles and one false negative diagnosis. Magnetic Resonance Imaging is a good exam to appreciate loco-regional extension of prostatic carcinoma.
对20例局限性前列腺癌患者进行了磁共振成像检查，并与根治性前列腺切除术后的病理结果进行了对照。肿瘤总是表现为低信号，6例伴有良性前列腺增生。正确评估了包膜外侵犯情况（20例中有17例）。在40例病例中，有6例假阳性诊断为精囊侵犯，原因是完整精囊出现低信号，还有1例假阴性诊断。磁共振成像是评估前列腺癌局部区域侵犯情况的良好检查方法。
