Forty patients with prostatic carcinoma or benign prostatic hyperplasia (BPH) underwent magnetic resonance (MR) imaging of the prostate. In vitro MR images of six prostate specimens were also obtained. The prostatic parenchyma was best evaluated by a T2-weighted spin-echo pulse sequence. The prostate both in patients with prostatic carcinoma and patients with BPH often had an inhomogeneous and nodular appearance on T2-weighted images. While most of the prostatic carcinomas appeared hyperintense relative to muscle and adjacent prostatic parenchyma, some of the hyperplastic nodules had a signal intensity similar to carcinoma. With current imaging techniques, MR imaging cannot differentiate prostatic carcinoma from BPH with certainty.
40例前列腺癌或良性前列腺增生（BPH）患者接受了前列腺磁共振（MR）成像检查。还获得了6个前列腺标本的体外MR图像。通过T2加权自旋回波脉冲序列能对前列腺实质进行最佳评估。前列腺癌患者和BPH患者的前列腺在T2加权图像上通常呈现不均匀的结节状外观。虽然大多数前列腺癌相对于肌肉和相邻前列腺实质呈高信号，但一些增生性结节的信号强度与癌相似。就目前的成像技术而言，MR成像无法确切区分前列腺癌和BPH。
