Sažetak
The aim of the present study was to investigate the interrelationship of presurgical Tc-99m-MDP scintimammography and post-surgical histopathological findings in 32 women with suspicious breast lesions. Anterior and lateral views of the breasts were acquired 10 min after i.v. injection of 740 MBq of Tc-99m-MDP. Scintimammograms were judged pathological if any increased accumulation of activity was found. Scintimammogrphy was normal in 10 patients and pathological in 22 patients. Histopathological findings revealed benign lesions in 7 patients and breast carcinoma in 25 patients. In 4 patients the uptake of Tc-99m-MDP was found in benign lesions. In total, there were 18 true positive findings, 4 true negative, 3 false positive and 7 false negative ones. Overall sensitivity of the scintimammography was 85%, specificity was 64%, positive predictive value was 82% and negative predictive value was 70%. In conclusion, our results are somewhat disappointing; scintimammography alone does not discriminate breast lesions accurately.
