目的 评价比较CT与PET对脊椎转移瘤的诊断价值。方法 34例病人 ,男 2 8例 ,女 6例 ,年龄 2 4～ 74岁。 34例原发灶明确。分别对其CT与PET检查结果进行比较。结果 34例中共侵犯椎骨 5 9个 ,包括颈椎 1个 ,胸椎 2 4个 ,腰骶椎 34个。CT与PET结果完全符合 2 5例 ,占 73 5 % (2 5 / 34 ) ;部分符合 7例 ,占 2 0 6 % (7/ 34 ) ;完全不符合 2例 ,占 5 9% (2 / 34 )。 5 9个椎骨中完全符合 45个椎骨 ,占 76 3% (45 / 5 9)。结论 CT与PET均不能作为脊椎转移瘤的常规检查 ,但是全身PET可能是探测已知原发肿瘤患者脊椎转移的有效方法
Objective To evaluate the diagnostic value of CT and PET in spinal metastases. Methods 34 patients, 28 males and 6 females, aged 24 to 74 years old. 34 cases of primary lesions were clear. The CT and PET examination results were compared. Results In 34 cases, the Chinese Communist Party invaded 59 vertebrae, including 1 cervical vertebrae, 24 thoracic vertebrae, and 34 lumbosacral vertebrae. The CT and PET results were in full compliance with 25 cases, accounting for 73.5% (2 5 / 34); partially met 7 cases, accounting for 20.6% (7/34); totally no 2 cases, accounting for 59% (2 / 34). Five of the 9 vertebrae were in full compliance with 45 vertebrae, accounting for 76 3% (45/59). Conclusion Both CT and PET cannot be used as routine examinations of spinal metastases, but whole body PET may be an effective method to detect spinal metastases in patients with known primary tumors.
