作者对18例活检证实前列腺癌和可疑骨转移的病人作了MRI研究。另外对6例D_2期前列腺癌在MRI上有骨转移的证据、在激素治疗者中进行不定期MRI随访。MRI用0.5T,T_1加权(TR/TE=450/20)对骨骼和转移淋巴结扫描,包括从腰骶关节至尽可能高度(一般是颈中段)的0.5cm层厚矢状面成象,并作上至腹主动脉分叉处骨盆的1.0cm层厚横断成象。如果病人有症状提示可能骨转移时,除了获得脊柱和骨盆症状区的T_1加权象外,
The authors performed an MRI study of 18 patients who had been biopsy-proven for prostate cancer and suspected bone metastases. In addition, evidence of bone metastases was found on MRI in 6 cases of D2 prostate cancer, and MRI follow-ups were performed occasionally in hormone therapy patients. MRI was performed on 0.5T, T_1-weighted (TR/TE=450/20) scans of bone and metastatic lymph nodes, including 0.5cm layer thickness sagittal plane imaging from the lumbosacral joint to the highest possible height (usually the middle neck). A 1.0 cm slice of the pelvis from the bifurcation of the abdominal aorta was transected and imaged. If the patient has symptoms suggesting possible bone metastases, in addition to obtaining a T_1 weighted image of the spine and pelvic region,
