Helical CT angiography of living renal donors: comparison with 3D Fourier transformation phase contrast MRA.
OBJECTIVE
The purpose of this study was to determine whether helical CT angiography (CTA) or MR angiography (MRA) is the optimal method to use as a preoperative examination for anatomic arterial assessment of living renal donors.


METHODS
Eighteen candidates to be renal donors underwent helical CTA, 3D Fourier transformation phase contrast (3D-FT-PC) MRA, and digital subtraction angiography (DSA). The CTA and MRA were interpreted separately by three readers independently, and these results were correlated with the findings of DSA.


RESULTS
DSA showed nine accessory renal arteries and 10 prehilar branches. CTA revealed seven or eight accessory renal arteries. MRA showed six or seven accessory arteries. Of 10 prehilar branches, 7-9 branches were detected with CTA and 5-8 branches with MRA.


CONCLUSIONS
Helical CTA is superior to 3D-FT-PC MRA for evaluating the arterial anatomy of living renal donors.
