Abstract
Objective To explore the value of SPECT / CT fusion imaging in the diagnosis of bone metastasis of lung cancer .Methods A total of 160 patients who were pathologically diagnosed with lung cancer were examed by whole body bone imaging and SPECT / CT fusion imaging ,the resulting images were observed and analyzed ,as well as the accuracy in diagnosis of lung cancer patients with bone metastases through different imaging methods were judged .Results After examination ,there were 52 patients had bone metastasis in lung cancer .The sensitivity of whole body bone imaging was 59 .6% ,specificity was 37 .0% ,accuracy of diagnosis was 44 .4% .The sensitivity of SPECT / CT fusion imaging was 96 .2% ,specificity was 88 .0% ,accuracy of diagnosis was 90 .6% .The negative pre-dictive value of whole body bone imagirg and SPECT /CT fusion imaging were 40 .40% and 95 .95% respectively ,the positive predictive value were 50 .82% and 81 .97% respectively .The accuracy rate of SPECT /CT fusion imaging were significant higher than that of whole body bone imaging (P < 0 .05) .Conclusion SPECT / CT fusion imaging has higher value in diagnosis of bone metastasis of lung cancer ,compared to whole body bone imaging .关键词
