比较临床评估、计算机断层扫描（CT）和磁共振（MR）成像在区分B期和C期前列腺癌中的敏感性、特异性、准确性和阳性预测值和阴性预测值。46例接受根治性直肠癌切除术的患者被纳入研究。手术-病理分期被认为是“真实的衡量标准”。临床分期的准确性为61%，CT为65%。MR成像的准确性取决于仪器参数和所用的截面。当仅分析横向T1加权图像时，MR准确性为61%。然而，当横向T1和T2加权图像补充额外的T2加权冠状或矢状图像进行研究，准确性增加到83%。目前，磁共振成像是最准确的诊断方法，局部分期的前列腺癌，但最佳的结果，需要多个序列和两个正交平面的成像。
The sensitivity, specificity, accuracy, and positive and negative predictive values of clinical assessment, computed tomography (CT), and magnetic resonance (MR) imaging were compared in the differentiation of stage B from stage C prostatic carcinoma. Forty-six patients who had undergone radical prostatectomy were included in the study. Surgical-pathologic staging was considered the "truth measure". Clinical staging had an accuracy of 61%, and CT, 65%. Accuracy for MR imaging depended on the instrument parameters and plane of section used. When only transverse T1-weighted images were analyzed, MR accuracy was 61%. However, when transverse T1- and T2-weighted images supplemented by additional T2-weighted coronal or sagittal images were studied, accuracy increased to 83%. At present, MR imaging is the most accurate diagnostic modality for the local staging of carcinoma of the prostate, but for optimal results, multiple sequences and two orthogonal planes of imaging are needed.
