A comparison of three-dimensional spiral computed tomoangiography with renal angiography in the live-donor work-up

Abstract

The purpose of this study was to investigate the safety and efficacy of three-dimensional spiral computed tomoangiography (3-D spiral CTA) of the abdomen as a substitute for renal angiography in the evaluation of potential live kidney donors. Two of 10 potential live renal donors underwent 3-D spiral CTA only, whereas the remaining 8 underwent 3-D spiral CTA and renal angiography before transplantation. 3-D spiral CTA and renal angiography results were compared and correlated with intraoperative findings. In all 8 cases in which 3-D spiral CTA and renal angiography were compared, the number of arteries was correctly identified by both modalities. In this limited study, 3-D spiral CTA provided the same information as did angiography. According to these findings, 3-D spiral CTA might be used as an alternative to renal angiography, though a larger series is needed to determine whether it could replace renal angiography for all potential live-donor work-ups.

Cortical and subcortical volumes in adolescents with alcohol dependence but without substance or psychiatric comorbidities

“…This method has been used successfully in a number of recent investigations (Corthorn et al, 1997, Rinehart et al, 1997, Markov et al, 1997, Figueroa et al, 1997, Angstrom et al, 2004, Sameti et al, 2011). The brainstem was excluded because the shape model used in FIRST extended beyond the inferior boundary of the images; left and right volumes were added to create a total volume for each of 8 subcortical structures.…”

Assessment of donor kidney anatomy

“…Twenty‐nine studies published from 1995 to 2006 compared operative findings with CT angiographic findings 3,5,6,8,9,12–35 . The sensitivity in detecting accessory renal arteries ranged from 40%‐100% (mean 84%).…”
