Applications of specific vascular opacification in CT of the upper abdomen

Selective visualization of the arterial and venous structures by CT slices during the early vascular phase after a bolus injection has proven to be a great value in resolving the problems of false images, created by incorporation of these vascular structures in the silhouettes of abdominal organs. This constitutes an important advance in the study and differentiation of pseudopancreas pathology, pseudolacunar images in the hapatic parenchyma and in the study of the porta hepatis.
