Abstract
By scanning the brain first at 100 and then at 140 kVp [peak] blood and Ca or I solutions could be distinguished, in vivo. The higher atomic number of Ca or I caused their CT [computed tomography] values to decrease significantly while blood showed no significant change. This principle was applied to 8 patients with hemorrhages, calcified lesions or I contrast augmented lesions. Hemorrhages showed no significant change with change in kVp, while the lesions containing Ca or I showed a highly significant change. This is a useful maneuver for determining the nature of a high-value lesion.This publication has 1 reference indexed in Scilit:
