[Usefulness of pancreatic scintilography in clinical diagnosis].

Our experience in pancreatic scintigraphy is presented in this paper. It was used as radioactive substance 75 semetionina. 21 patients with pancreatic pathology and 6 controls constituted the clinical material. The scintigraphy studies showed an homogenous distribution of the radioactive material in the control group. In 7 cases a defect of concentration was showed. The diagnosis of carcinoma were made with surgery in all of them. Similar findings were demonstrated in cases of pancreatic pseudocyst. Irregular distribution was noted in patients with pancreatitis. We concluded that in same instances pancreatic scintigraphy can be useful for differential diagnosis in the clinical field.

[Ventilation, diffusion and pulmonary perfusion studied by 133 Xe].

The pulmonary function has been studied by several methods using radioactive gases since 1955. Knipping and col. reported the first study with 133Xe in the evaluation of the gas distribution in pulmonary ventilation. In this study, we report the pulmonary function in 40 normal persons, evaluated by injection in a peripherical vein of this radioactive substance. The elementary respiratory functions: ventilation, diffusion and perfusion were calculated by distribution curves of 133Xe and we obtained the V/P index is very important for the diagnosis and therapeutic evaluation of the pulmonary function. Comparative studies with several examples of human pulmonary disease are in progress in our laboratory.
