NONINVASIVE 3-DIMENSIONAL ELECTRON BEAM COMPUTED TOMOGRAPHY ANGIOGRAPHY RENAL ARTERIES

Abstract

Three dimensional electron beam computed tomography (EBCT) angiography is a useful technique for the depiction of renal artery lesions and for vascular variants. Generic advantages of ultrafast tomography and thin slice imaging, are registered volume data set with overlapping reconstructions to reduce partial volume effect and effective contrast medium utilization. Ultrafast EBCT with its axial images and several three dimensional techniques, is easy to apply, functional and accurate for renal vascular anatomy and renal artery stenosis (RAS) and useful for detection of extension of the trauma and intravascular tumor in partial nephrectomy.
Key Words: EBCT, Three dimension, Angiography, UPJ (ureteropelvic junction) stenoses, Trauma.
