A total of 111 patients with clinically localized prostate cancer (stage A or B) underwent endorectal surface coil magnetic resonance imaging (MRI) for preoperative staging of the disease. Of the patients 43 with advanced disease on endorectal surface coil MRI (33 with stage C and 10 with stage D disease) received alternative therapy, as did 21 with stage B disease on MRI. The overall staging accuracy for the remaining 47 patients was 68%, with a 74% accuracy rate in staging advanced disease and a 91% accuracy rate for depiction of seminal vesicle involvement. Failure to recognize microscopic extracapsular disease was responsible for the majority of staging inaccuracies in this highly select group of patients. Endorectal surface coil MRI provides extremely high resolution images of the prostate and periprostatic structures, and is an exciting new modality for local staging of prostatic carcinoma.
共有111例临床局限性前列腺癌（A期或B期）患者接受了直肠内表面线圈磁共振成像（MRI）检查，以对疾病进行术前分期。在这些患者中，43例在直肠内表面线圈MRI检查中显示为晚期疾病（33例为C期，10例为D期）的患者接受了替代治疗，MRI显示为B期疾病的21例患者也接受了替代治疗。其余47例患者的总体分期准确率为68%，晚期疾病分期准确率为74%，精囊受累的显示准确率为91%。在这一高度选择的患者群体中，大多数分期不准确是由于未能识别微小的包膜外疾病。直肠内表面线圈MRI提供了前列腺和前列腺周围结构的极高分辨率图像，是前列腺癌局部分期的一种令人兴奋的新方法。
