[Detection of reflux esophagitis following gastrectomy using cholescintigraphy].

A total of 53 patients after gastrectomy were examined by hepatobiliary scintigraphy with i.v. administration of 25 MBq of 99mTc-BIDA.

[Evaluation of the indicators of dynamic renal scintigraphy using the radiopharmaceutical preparation In-113m-DTPA in patients with chronic glomerulonephritis before and after heparin therapy].

In 70 patients with a morphologically verified diagnosis of chronic glomerulonephritis, functional computer-aided scintigraphy of the kidneys was performed before and after heparin therapy. Improvement in the scintigraphic parameters following heparin therapy was apparent as the reduction of the time of the radiopharmaceutical passage and the decrease of spastic excretory disturbances. A certain deterioration of the scintigraphic parameters after heparin therapy was found in patients with fibroplastic and focal sclerotic glomerulonephritis associated with renal insufficiency.
