Abstract:
Objective To evaluate 99tcm-DTPA nuclear dynamic imaging in distinguishing the renal occupied disease.Methods A total of 164 in-patients with renal occupied disease who underwent surgery were included.According to the pathological diagnosis,119 patients had malignant tumors,and 45 patients had benign diseases.All patients’ imaging was retrospectively analyzed.Application of 99Tcm-DTPA nuclear dynamic imaging in renal occupied disease was compared with ultrasonography (US),computed tomography (CT),magnetic resonance imaging (MRI),intravenous pyelogram (IVP),and positron emission tomography (PET)-CT.Results The accuracy rates of different imaging methods in distinguishing between renal malignant and benign disease were 99Tcm-DTPA (84 ％,45 ％),US (72 ％,64 ％),CT ( 91％,92 ％),MRI (50 ％,67 ％),IVP (50 ％, 17 ％), respectively.The diagnostic accuracy rate of PET-CT for malignant tumors was 67 ％.The accuracy rates of 99Tcm-DTPA in distinguishing different phases of renal cell carcinoma were statistically significant (x 2 =83.4, P ＜ 0.01), while the accuracy rates in distinguishing renal cyst from renal angiomyolipoma were not statistically different.With the greater diameter, the diagnostic accordance rate is higher (x 2 =16.05,P ＜ 0.05).Conclusion 99Tcm-DTPA could be used not only to evaluate the renal function quantificationally,but also be helpful to distinguish renal malignant tumor from benign disease.
