ABSTRACT
Objective To assess the diagnostic value of mammography,ultrasound and 18F-fluorodeoxyglucose(18F-FDG) dual-head coincidence(DHC) imaging in the detection of primary breast cancer. Methods The results of 54 female patients with 57 breast lesion sites examined by mammography,ultrasound and 18F-FDG dual-head coincidence(DHC) imaging were analysed and compared with pathologic findings.The sensitivity of mammography was compared with combined mammography with ultrasound or triple-tests,and the sensitivity of 18F-FDG DHC imaging was compared with combined mammography and ultrasound. Results The individual sensitivities of mammography,ultrasound and 18F-FDG DHC imaging in the diagnosis of primary breast cancer were 89.13%,91.30% and 91.30%,respectively,those for specificities were 72.73%,72.73% and 63.64%,respectively,and those for accuracies were 85.96%,87.72% and 85.96%,respectively.The sensitivity,specificity and accuracy of combined mammography with ultrasound were 100%,63.64% and 92.98%,respectively,and those of triple-tests were 97.83%,81.82% and 94.74%,respectively.Combined mammography with ultrasound and triple-tests were more sensitive than mammography(P0.05).Triple-tests were more sensitive than combined mammography with ultrasound(P
