This is a prospective comparison of SPECT versus planar imaging of the lumbosacral spine and pelvis, performed in order to assess which technique was more useful in clinical practice. One hundred adults were studied with both techniques, and abnormalities uncovered by either imaging method were graded 1-4 based on the lesion's relative uptake intensity. SPECT imaging significantly improved lesion detection, especially in conditions resulting in only low grade tracer uptake on planar studies. Precision in anatomic localization furthermore improved the quality and usefulness of diagnostic information resulting from SPECT imaging compared to planar examinations. SPECT is recommended for routine imaging of the lumbosacral spine and pelvis in symptomatic patients, especially when planar examinations are normal or equivocal.
这是一项关于单光子发射计算机断层扫描（SPECT）与腰骶椎及骨盆平面成像的前瞻性比较研究，旨在评估哪种技术在临床实践中更有用。对100名成年人同时采用这两种技术进行研究，根据病变的相对摄取强度，将两种成像方法发现的异常分为1 - 4级。SPECT成像显著提高了病变的检测率，尤其是在平面研究中仅显示低级别示踪剂摄取的情况下。与平面检查相比，SPECT成像在解剖定位上的精确性进一步提高了诊断信息的质量和实用性。对于有症状的患者，建议对腰骶椎及骨盆进行SPECT常规成像，尤其是当平面检查结果正常或不明确时。
