Centellografía hepatobiliar cuantitativa con 99m Tc DISIDA en sujetos normales y en cirróticos alcohólicos. / [Quantitative Tc 99m - DISIDA hepatobiliary scintigraphy in normal and cirrhotic alcoholic subjects]

ABSTRACT

Quantitative hepatobiliary scintigraphy (Q.H.S.), with 99m Tc-DISIDA was performed on 15 control subjects and 32 alcoholic cirrhotic patients (A.C.). We used a dynamic planar scintigraphy (30 seg/frame, up to 45 min) technique following injection intravenously of 99m Tc-DISIDA. Time/activity curves were obtained from the right upper lobe of the liver and the 1) slope uptake, 2) half-time (T 1/2 min) uptake, 3) excretion half-time (T1/2 min), were measured from the curve. The A.C. were divided in two groups, IIA (n = 32) and IIB (n = 6) if the excretory curve show negative slope or not respectively. RESULTS: The mean value (+/- 1 D.S. 95
