[Structure of functional scintigraphic images during the development of gallbladder bile reflux into the intrahepatic ducts].
The authors proposed a method of cholescintigraphy with functional imaging reflecting RP distribution within the entire area in the field of vision of a gamma-chamber detector taking account of the type of motor activity of the gall bladder. This method was based on plotting an activity-time curve along the outer contour of a gall bladder image, the determination of moments of change in gall bladder motor activity on this curve, and the calculation of corresponding gradients of RP accumulation and clearance functions represented on an image where the color of each element was determined by a sign of the gradient and its intensity--by its absolute value. The use of this method in 92 patients made it possible to reveal conditions with possible B-bile reflux into the intrahepatic ducts, and to raise its diagnostic accuracy by 7% as compared to a routine analysis of activity-time curves by decreasing the number of false-negative results.
