A pilot study of MRI was carried out on three normal male volunteers and 15 patients with tumours in the prostate or bladder. One advantage of the method is the ability to obtain images in three planes, without moving the patient. It is therefore possible for the first time to demonstrate lesions in the base of the bladder in their cranio-caudal extent. Tissue contrast of MRI, using long sequences with suitable proton or T2-weighted images is better than with CT and provides more accurate diagnosis. Even non-expansive tumours within the gland can be differentiated from normal glandular tissue. It has been noted that carcinoma of the prostate in the T2-mode provides an increased signal, whereas tumours of the bladder look dark. Up to a point, tissue characterisation may be possible.
对三名正常男性志愿者和15名患有前列腺或膀胱肿瘤的患者进行了MRI初步研究。该方法的一个优点是能够在不移动患者的情况下获得三个平面的图像。因此，首次有可能在颅尾方向上显示膀胱底部的病变。使用具有合适质子或T2加权图像的长序列进行MRI的组织对比度优于CT，并且能提供更准确的诊断。即使是腺体内部的非扩展性肿瘤也可以与正常腺组织区分开来。已经注意到，T2模式下的前列腺癌信号增强，而膀胱肿瘤看起来呈暗色。在一定程度上，可以进行组织特征描述。
