Three patients are presented with a history of chronic watery diarrhea due to bile acid malabsorption, proved by the tauro-23[75Se]selena-25 homocholic acid test and an unequivocal response to cholestyramine therapy. Fecal fat tests, Schilling tests, and barium studies of the small intestine and colon were all normal. Jejunal biopsies were normal but(More)
We report a 60-year-old man with intermittent diarrhea for 15 years which was worsened by cholecystectomy. The results of routine laboratory tests, x-ray studies of the gut, and endoscopy were normal. Fecal fat excretion was normal, but total bile acid excretion was increased in the alkaline feces. The retention of 75SeHCAT was low. Jejunal mucosal biopsy(More)
A simplified and efficient procedure for 99mTc-HMPAO-labelling of leukocytes is described. For this purpose, the pH and concentration of the 99mTc-HMPAO preparation was modified. Leukocytes were isolated from a 20 mL mixture of patient blood, 5 mL ACD and 0.8 mL methylcellulose after 1 h sedimentation of erythrocytes and centrifugation (at 400 g) of the(More)
The study presents preliminary results and suggests the role of scintigraphy of synthetic vascular prosthesis by 99mTc-HMPAO labelled leukocytes for detection of graft infections. Analysis of the results obtained revealed true positive in 6, true negative in 3 and suspicious findings in 3 patients (in one of them the suspicious was confirmed on(More)
Hepatic radionuclide angiography (HRA) is a recognised method of investigation of liver blood flow disorders caused by: diffuse and focal diseases of liver parenchyma or disorders of blood flow in extrahepatic liver vessels. Hepatic perfusion index (HPI) based on Sarper's slope method is significantly lower in patients with e.g. liver cirrhosis, malignant(More)
