Twenty-nine prostatic cancer patients were evaluated for staging purpose by Magnetic Resonance (MR). MR findings were correlated with the pathologic examination in 18/29 patients who underwent radical prostatectomy. Four MR staging parameters were evaluated individually: periprostatic fat; periprostatic venous plexus; seminal vesicles and pelvic adenopathy. MR correctly staged 16/18 patients, with one case of overstaging and one case of understaging. The diagnostic accuracy of MR in differentiating intracapsular stage B from extracapsular stage C was 87%, with a sensitivity of 90% and a specificity of 87%. MR and CT results agreed in 4 of the 7 operated patients who were examined with both techniques; in 3 cases there was disagreement, and MR was correct.
为了进行分期评估，对29例前列腺癌患者进行了磁共振（MR）检查。在接受根治性前列腺切除术的29例患者中，有18例的MR检查结果与病理检查结果进行了对比。分别对四个MR分期参数进行了评估：前列腺周围脂肪；前列腺周围静脉丛；精囊和盆腔淋巴结病变。MR对18例患者中的16例进行了正确分期，1例过度分期，1例分期不足。MR区分包膜内B期与包膜外C期的诊断准确性为87%，敏感性为90%，特异性为87%。在同时接受两种检查的7例手术患者中，MR和CT结果在4例中一致；在3例中存在分歧，而MR结果正确。
