Clinical application: Dynamic scintigraphy of liver and heart of a patient having liver cirrhosis after intrasigmoidal administration of 13N-ammonia (pH 8.1) were performed. Simultaneously, continuous measurments of radioactivity at the left side abdomen and the left temporal region were done by using a scintillation detector for renography. Successive measurement of radioactivity of blood was also carried out. 2) Comstruction of functional images of liver and heart: By using digital radioisotope image of liver and heart of the patient after intrasigmoidal administration of 13N-ammonia, the maps with respect to parameters described in the pervious paper were constructed.
