    Notes: Abstract The activity concentrations of 99mTc-HMPAO in brain after intravenous injection were evaluated in 25 patients using SPECT. With additional first pass studies of heart and brain with the short lived isotope 195mAu, the cardiac output and the mean cerebral transit times of the patients were measured a short time before the HMPAO injection. The time dependence of 99mTc-HMPAO activity in the brain was registered during the first 5 min after injection over both hemispheres. Using a simplified three compartment model it was possible to calculate the mean retention fraction of HMPAO in brain from the time activity curves. It could be shown that the regional cerebral blood flow in ml/min per 100 g can be calculated from the activity concentration of HMPAO in the brain, the cardiac output and the retention fraction. In 15 of the 25 cases the rCBF was measured using the planar 133Xe inhalation method as a reference. We found a significant correlation between the mean hemisphere CBF from our method and the mean hemisphere grey matter CBF from the Xenon method with a correlation coefficient of 0.73.

    Notes: Abstract Thirty-three neonates and infants with cholestatic syndromes of various etiologies were evaluated by cholescintigraphy and ultrasound examinations. The results of these two diagnostic procedures were compared with the final diagnosis as confirmed by liver biopsy and/or laparotomy and the clinica follow-up of the infants. Fourteen patients had an obstructive cholangiopathy (11 biliary atresia, 2 choledochal cysts, 1 congenital choledochal stenosis), 13 had neonatal hepatitis, and 6 had cholestasis of another etiology. Typical ultrasonic and/or scintigraphic findings confirmed or excluded the need for surgical exploration in 28 patients. Thus, for must infants with cholestatic syndromes it is possible to differentiate the cause without invasive diagnostic techniques such as liver biopsy or exploratory laparotomy.
