Comparative evaluation of imaging quality of the adrenal artery in experimental animals

Abstract

The imaging quality of the adrenal arteries in experimental animals is assessed by the data of angiography for further study of different embolization techniques. The study was performed on the material of sexually mature rabbits (n=5) and pigs (n=5). All animals underwent multispiral computed tomography (MSCT) in angiography mode via Briliance 64 (Phillips) apparatus followed by invasive angiography of aorta and visceral arteries using mobile C-arms apparatus (Siemens). Intergroup analysis, involving the results of MSCT-angiography and invasive angiography of aorta and visceral arteries, revealed unsuitability of rabbits for selective catheterization of the adrenal arteries due to their small diameter. Nevertheless, invasive arteriography in pigs ensures bilateral imaging of the main branches of arteries supplying the adrenal glands to be considered suitable for the study of embolization techniques.
