VALUE OF SPECT/CT BONE TOMOGRAPHY IN DIFFERENTIAL DIAGNOSIS OF LUMBAR AND PELVIC LESIONS IN PATIENTS WITH MALIGNANT TUMOR
Objective To investigate the value of 99Tcm-MDP SPECT/CT bone tomography in the differential diagnosis of lumbar and pelvic lesions in patients with malignant tumor.Methods SPECT/CT bone tomography was performed for 135 patients with malignant tumor who had radioactive anomalies in the lumbar vertebra and the pelvis on 99Tcm-MDP whole-body scan (WBS),and the data of SPECT/CT bone tomography were obtained.Two experienced senior nuclear medicine physicians read the radiographs together.These data were analyzed to give a final diagnosis.The proportion of benign or malignant lesions or lesions without a definite diagnosis evaluated by WBS or SPECT/CT bone tomography was calculated and compared.Results For all 135 patients,215 lesions were found by WBS,among which 150 (69.77％) had a definite diagnosis,including 130 benign lesions and 20 bone metastatic lesions.A total of 234 lesions were found by SPECT/CT bone tomography,among which 230 (98.29％)had a definite diagnosis,including 180 benign lesions and 50 bone metastatic lesions.SPECT/CT bone tomography had a significantly higher diagnostic rate of lumbar and pelvic lesions than WBS (x2 =70.09,P＜0.05).Follow-up results showed that of all 234 lumbar and pelvic lesions,182 were benign lesions,most of which were degenerative lesions,and benign bone tumor was rare.Of all 234 lesions,52 (22.22％) were bone metastatic lesions of tumor.Conclusion In patients with malignant tumor,SPECT/CT bone tomography can find more lumbar and pelvic lesions than WBS,which significantly improves diagnostic accuracy.
