摘要
目的评价SPECT/CT同机融合显像对SPECT难于确诊骨病灶的诊断价值。方法对SPECT难于确诊的35例肿瘤患者的37个病灶行SPECT/CT同机融合显像。由2名经过放射学培训的核医学科医师盲法独立阅片。所有病灶均以病理、磁共振结果或6个月以上的随诊为最终诊断结果。结果SPECT±CT和SPECT/CT分别可对17个(17/ 37,45.95%)和30个(30/37,81.08%)病灶做出准确诊断,SPECT/CT诊断的正确率较SPECT明显提高(χ^2=9.855,P= 0.002)。SPECT、SPECT+CT和SPECT/CT诊断为性质待定的病灶,经随访确诊后恶性病灶所占比率分别为29.7%(11/ 37)、26.3%(5/19)和16.7%(1/6)。结论SPECT/CT同机融合显像有助于鉴别诊断SPECT难于确诊骨病灶的性质,应作为SPECT显像的重要补充。
Objective To evaluate radionuclide bone SPECT/CT fusion imaging in the assessment of foci bone metabolism classified as indeterminate on SPECT. Methods A total of 37 lesions in 35 patients without concrete diagnosis on SPECT underwent radionuclide bone SPECT/CT imaging. The final diagnosis of these patients were obtained with MRI, pathology or follow-up for more than six months. Results Among 37 equivocal lesions on bone SPECT, the diagnostic accuracy was 45. 95% (17/37) for SPECT+CT and 81.08% (30/37) for SPECT/CT, respectively (χ^2 =9. 855, P=0. 002). Of the equivocal lesions by SPECT, SPECT+CT and SPECT/CT, the ratio of malignancy was 29.7% (11/37), 26. 3% (5/19) and 16.7% (1/6), respectively. Conclusion Radionuclide bone SPECT/CT fusion imaging is of great importance in the assessment of foci bone metabolism classified as indeterminate on bone SPECT, and should be used as a valuable supplementary procedure to hone SPECT.
