Nuclear imaging, tomographic nuclear imaging, and gray scale ultrasound in the evaluation of the porta hepatis

Abstract

Twenty-six patients with an eqivocal portal defect on conventional nuclear images were evaluated with a multiplane tomographic nuclear scanner and gray scale ultrasound. In most cases the correct determination (normal or abnormal) for an area of decreased uptake could be made from the multiplane tomographic scans. When an abnormality was thus confirmed, further characterization was provided by ultrasound.
