[Thoraco-abdominal angiotomography. 280 explorations]

Angiotomography invariably imrpves the quality of the images obtained in vascular radiology, with respect to both vascular anatomy and pathology. Its contribution is obviously essential when, for technical reasons, arterial opacification is only mediocre (extended angiocardiopneumography). In the arteriolar study of deep seated or voluminous organs, its eliminates superimpositions, makes tri-dimensional study possible and provides a means of studying fine arterioles, useful in diagnosis and difficult to demonstrate using conventional techniques. Its principle limitations are technological in character. Accepting precise and clearly defined rules in its indications and realisation, appropriate equipment, and a constant effort in the analysis and reading of its results, it is reasonable to hope that angiotomography will quickly add a new dimension to vascular studies.
