Abstract:
Objective:To evaluate the accuracy and ch aracteristics of combined use of 99Tcm-sulfur colloid (SC)and 9 9Tcm-diethyliminodiacetic acid (EHIDA)imaging on the diagnosis of hepat ic adenoma (HA). Methods:8 patients with HA were involved in this study.All of them were studied by nuclear medicine (NM)with dual-radiopharmaceuticals.The 99 Tcm-SC imaging was perfomed first ,then the 99Tcm-EHIDA im aging two days later,and the ratios between lesions and normal liver tissue(L/N) were calculated in terms of different counts within the same size regions of int erest (ROI) in different phases(30min,1h and 2h respectively).Some of the cases were also analysed by CT and/or MRI within one week before the operations. Results:All of the cases were submitted to surgical treatment and c onfirmed diagnosis of HA by pathology. For HA, scintigrahy presented a accuracy of 100%(8/8),which was higher than that of CT and MRI comparatively.For 99 Tcm-EHIDA imaging,there were significant differences in L/N ratios among different phases(30min,1h and 2h). Conclusion:The results show that radionuclide imaging proved to be a safe,invasive and effcetive method on the diagnosis and differential diagnosis of HA,especially ,when CT and/or MRI findings are not typical.
