Diagnostic value of ~(18)F-FDG PET and ~(99)Tc~m-MDP imaging in detection bone metastases / 肿瘤研究与临床

ABSTRACT

Objective To investigate the diagnostic value of 18F-FDG PET and 99Tcm-MDP imaging in detection bone metastases. Methods 93 patients were undergone 18F-FDG PET and 99Tcm-MDP imaging within 2 weeks. The results of the 2 different modalities were analyzed. Results Of the 93 patients, 64 patients were found to have bone metastases by PET and MDP imaging. Among the 64 patients, 43 patients were found both positive PET and MDP. 16 patients had positive PET whereas negative MDP. 5 patients had negative PET whereas positive MDP. The sensitivity, specificity and accuracy of 18F-FDG PET and 99Tcm-MDP imaging were 92.2 %, 75.0 %(P 0.05), 92.5 %,76.3 %(P
