作者选用T_1WI、短反转时间反转恢复(STIR)、快速自旋回波(FSE)、快速自旋回波脂肪饱和(fat-saturated FSE)和反转恢复快速自旋回波(IRFSE)等不同MR扫描序列对椎体转移癌病灶的显示和病灶数目的检出率进行对比研究。91例椎体转移癌,男44例,女47例,年龄5～87岁(平均58.76岁)。125个脊椎MR检查图像中,19个颈椎、52个胸椎和54个腰椎。MR场强为1.5T,颈椎扫描野为24cm,胸腰为36cm。扫描层厚5mm,层间距0.5mm。为便于对比,作者将各种检查序列分成三个组,每组均包括T_1WI和STIR,这两项检查序列与FSE对比组成第一组
The authors used T_1WI, STIR, FSE, fat-saturated FSE, and inversion recovery IRFSE to perform various MR scans. The sequence of the vertebral metastases and the detection rate of the number of lesions were compared. There were 91 cases of vertebral metastases, 44 males and 47 females, aged 5 to 87 years (average 58.76 years). Of the 125 spine MR examination images, 19 were cervical, 52 were thoracic, and 54 were lumbar. The MR field strength is 1.5T, the cervical scan field is 24cm, and the thoracolumbar is 36cm. Scanning layer thickness 5mm, layer spacing 0.5mm. For ease of comparison, the authors divided the various test sequences into three groups. Each group included T_1WI and STIR. The two test sequences were compared with the FSE to form the first group.
