作者用MRI研究前列腺癌患者骨转移的部位、转移病灶的信号强度和骨硬化的程度及其相关性,并与骨盆部骨闪烁法作对比。选择确诊为前列腺癌并骨转移的10例、72个病变,年龄40～85岁。用场强1.5T超导型MR机,体表线圈,SE法。横断面上以前列腺为中心行层厚5mm,摄影后,再自腰椎至耻骨间行层厚8mm摄影,矢状面以腰椎、骶椎为中 The authors used MRI to study the location of bone metastases in prostate cancer patients, the signal intensity of metastatic lesions, and the degree of bone sclerosis and their correlation, and compared with the pelvic bone scintigraphy. The 10 cases and 72 lesions diagnosed as prostate cancer with bone metastases were selected and were 40 to 85 years old. Field strength 1.5T superconducting MR machine, surface coil, SE method. In the cross section, the prostate centered on the line was 5 mm thick. After the photographing, the thickness of the line between the lumbar spine and the pubic layer was 8 mm. The sagittal plane was taken from the lumbar spine and the sacral spine.
