目的:探讨64层螺旋CT在脊柱扫描中的临床应用及对脊柱转移瘤的诊断价值。材料与方法:收集脊椎转移瘤38例,男22例,女16例,年龄1.8岁～78岁,中位年龄37岁。因腰背部疼痛、下肢无力、贫血而进行病变椎体CT扫描,或因胸、腹部检查后,分析图象时偶尔发现椎体病变。原发肿瘤病史明确者24例,原因不明者14例经过随诊复查确诊为椎体转移瘤。结果:38例中,发病部位:颈椎(C3～6)5例;胸椎(T6～12)26例;腰椎3例;腰骶部4例。病变椎体呈楔形、双凹形改变19例;椎体骨质破坏、密度减低呈多椎体、跳跃式分布10例,单椎体骨质破坏26例。椎体骨质破坏呈筛孔样、虫蚀样、溶骨样改变32例;散在分布的斑块状的高密度灶呈成骨样改变4例;椎管后缘可见软组织肿块、硬膜囊被挤压11例。结论:64层螺旋CT检查在脊柱转移瘤的诊断中有重要价值,可为临床提供可靠的诊断信息。
Objective: To investigate the clinical application of 64-slice spiral CT in the diagnosis of spinal metastases and its diagnostic value. MATERIALS AND METHODS: Thirty-eight cases of spinal metastases were collected, including 22 males and 16 females, aged from 1.8 to 78 years old, with a median age of 37 years. Due to low back pain, leg weakness, anemia and vertebral body CT scan, or chest, abdominal examination, the analysis of images occasionally found vertebral lesions. Twenty-four patients with definite history of primary tumor and 14 patients with unknown cause were diagnosed as vertebral metastases by follow-up examination. Results: In 38 cases, the incidence sites were 5 cases of cervical (C3 ~ 6), 26 cases of thoracic (T6 ~ 12), 3 cases of lumbar and 4 cases of lumbosacral. Vertebral body was wedge-shaped, biconcave changes in 19 cases; vertebral bone destruction, reduced density was multi-vertebral body, jumping distribution in 10 cases, single vertebral bone destruction in 26 cases. Vertebral bone destruction was mesoporous, worm-eaten, osteolytic changes in 32 cases; scattered plaque-like high-density lesions showed osteoid changes in 4 cases; posterior edge of the soft tissue mass of the spinal canal, the dural sac It was squeezed in 11 cases. Conclusion: 64-slice spiral CT has important value in the diagnosis of spinal metastases, which can provide reliable diagnostic information for clinic.
