Complex radioisotopic examination of renal functions using SOPHA MEDICAL program system

Repeated isotopic scanning of the kidneys were made on a patient with complex renal diseases, on two consecutive days, in sitting and in lying position, resp. The scanning was done with 99mTc-MAG3 administered intravenously to the patient, starting computer scanning of gamma camera frames simultaneously. The data were evaluated by the SOPHA MEDICAL software of Sopha Medical GmbH, Frankfurt, Germany. It was observed that, in sitting position, the kidney perfusion, the early uptake, the tubular clearance and the ureter peristaltic are disturbed because of the compression of renal artery and ureter. These functions were recovered in the lying position. (R.P.) 14 refs.; 8 figs
