Retrospective study of renal images on bone scans

Renal images shown on 254 bone scans employing Tc 99m MDP were analyzed to evaluate the renal abnormalities. Among these cases, there were 43 cases of abnormal renal visualization. Of these abnormal cases, 27 cases were proved by laboratory data, radiographs, echograms, CT findings and autopsy records. 14 cases of renal abnormalities were presented; hydronephrosis due to ureteral obstruction (4 cases), renal dysfunction (3 cases), renal cell carcinoma (2 cases), contracted kidney (2 cases), nephrectomy (2 cases) and renal stone (1 case). Three cases showed super bone images with widespread metastatic lesions of malignant tumors. The remaining 10 cases were not revealed renal abnormalities from other clinical findings. (author)
