目的评估三种不同的磁共振（MR）成像技术的准确性，包括直肠内线圈，在分期prostate cancer.MATERIALS和METHODSMR成像进行了213例前列腺癌与常规体线圈，脂肪抑制和体线圈，并与直肠内线圈。放射科医生确定肿瘤侵入前列腺周围组织、神经血管束和精囊。每种技术分别进行评价，并在一个子集的74例患者的三种技术一起进行评价。两种体线圈技术获得的图像与直肠内线圈（组合A）和单独（组合B）获得的图像结合阅读。常规体线圈、脂肪抑制体线圈和直肠内线圈MR的总体准确率分别为61%、64%和54%。组合A和B的总体组准确度分别为57%和61%。发现组合A的读者间存在相当大的差异。结论没有任何技术可以高度准确地对早期前列腺癌进行分期。个别放射科医师使用直肠内线圈和体线圈组合确实实现了高度的分期准确性。
PURPOSETo assess accuracy of three different magnetic resonance (MR) imaging techniques, including the endorectal coil, in staging prostate cancer.MATERIALS AND METHODSMR imaging was performed in 213 patients with prostate cancer with a conventional body coil, with fat suppression and a body coil, and with an endorectal coil. Radiologists identified tumor invasion into periprostatic tissues, neurovascular bundles, and seminal vesicles. Each technique was evaluated separately, and in a subset of 74 patients the three techniques were evaluated together. Images obtained with the two body-coil techniques were read in combination with images obtained with the endorectal coil (combination A) and alone (combination B).RESULTSOverall accuracy for conventional body-coil, fat-suppressed body-coil, and endorectal-coil MR was 61%, 64%, and 54%, respectively. Overall group accuracy for combinations A and B was 57% and 61%. Considerable interreader variability was found for combination A.CONCLUSIONNo technique was highly accurate for staging early prostate cancer. Individual radiologists did achieve a high degree of staging accuracy with the endorectal-coil and body-coil combination.
