Twenty-two patients with prostatic carcinoma have been studied by magnetic resonance imaging (MRI). Twenty-three examinations have been done for 2 stage A, 11 stage B, 2 stage C and 7 stage D. Prostatic signal and locoregional extension have been compared with rectal examination and the 3 prostatectomies. Cancer looked homogeneous in 4 cases, heterogeneous in 10 cases with a nodule in 5 cases either with hyper of hyposignal compared to the normal prostate. Local extension in stages C and D is seen, especially to the periprostatic fat and seminal vesicles. MRI appears to be sensitive but poorly specific in the diagnosis of prostatic cancer. On the other hand, it is an interesting examination in the staging of prostatic cancer. These results must be confirmed with more comparisons of images and prostatectomy specimens.
对22例前列腺癌患者进行了磁共振成像（MRI）研究。针对2例A期、11例B期、2例C期和7例D期患者进行了23次检查。将前列腺信号及局部扩散情况与直肠指检及3例前列腺切除术结果进行了比较。4例癌症表现为均匀性，10例为异质性，其中5例有结节，与正常前列腺相比呈高信号或低信号。可见C期和D期有局部扩散，尤其是累及前列腺周围脂肪和精囊。MRI在前列腺癌诊断中似乎具有敏感性，但特异性较差。另一方面，它在前列腺癌分期方面是一项有价值的检查。这些结果必须通过更多图像与前列腺切除标本的比较来加以证实。
