摘 要: | 目的:探讨脊柱转移瘤的MRI诊断及SPIR技术在MRI诊断中的价值。材料和方法:回顾40例经临床、病理证实的脊柱转移瘤的资料,分析肿瘤的MRI征象,并与X线平片、CT、核素骨扫描作一对照。结果:脊柱转移瘤的MRI表现为受累椎体信号异常、变扁膨出、多椎体受累、跳跃征、椎间隙扩大,多累及椎弓根、椎间盘不受侵犯。MRI尤其是SPIR技术的应用较X线平片(5/18)、CT(3/5)、核素骨扫描(8/19)更敏感地显示病灶。

Abstract: | PURPOSE:To study MRI diagnosis of vertebral metastases and to evaluate the SPIR techique on MRI. MATERIALS and METHODS:We analysed MRI apparance of 40 patients, clinical and pathologically proved vertebral metastases,and compared the sensitivities of MRI and plain radiograph, CT and radionuclide bone scans in detecting vertebral metastases. RESULT: On MRI, the vertebral metastases presented as adnormal signal intensity, flatted and expansion in the involved vertebral, non-continuous sign of multiple metastases, expanded intervertebral space, involvment of pedicle of vertebral arch and no involvement of intervertebral disc. MRI has a higner sensitivity in detecting vertebral metastases than plain radiograph,CT and radionuclide bone scans,especially when it used with SPIR technique. |
