STUDY DESIGN
A controlled prospective blinded study.
OBJECTIVES
To compare the diagnostic power of myelography, computed tomography and magnetic resonance imaging in the diagnosis of low lumbar disc herniation.
METHODS
Eighty patients with monoradicular sciatica were examined by myelography, computed tomography, and magnetic resonance imaging, and all underwent subsequent surgery. The images were evaluated twice in a blinded fashion, and the diagnostic power of the modalities was expressed by a decision-analytic regret function.
RESULTS
In 57 patients (71%) a disc herniation at the expected level was disclosed at surgery. The largest amount of diagnostic information was gained from computed tomography, followed by magnetic resonance imaging and myelography. Both computed tomography and magnetic resonance imaging were significantly informative, whereas this was not the case for myelography.
CONCLUSION
The results indicate that computed tomography or magnetic resonance imaging should be the first choice for imaging in patients with suspected lumbar disc herniation.
研究设计
一项对照前瞻性盲法研究。
目的
比较脊髓造影、计算机断层扫描和磁共振成像在诊断低位腰椎间盘突出症中的诊断能力。
方法
对80例单根性坐骨神经痛患者进行脊髓造影、计算机断层扫描和磁共振成像检查，所有患者随后均接受手术。图像以盲法进行两次评估，各检查方法的诊断能力通过决策分析后悔函数表示。
结果
57例患者（71%）在手术中发现预期节段的椎间盘突出。计算机断层扫描获得的诊断信息最多，其次是磁共振成像和脊髓造影。计算机断层扫描和磁共振成像均具有显著的信息量，而脊髓造影并非如此。
结论
结果表明，对于疑似腰椎间盘突出症的患者，计算机断层扫描或磁共振成像应作为首选的影像学检查方法。
