Helical CT: Angiography of Living Renal Donors: Comparison with 3D Fourier Transformation Phase Contrast MRA.
J Comput Assist Tomogr 22: 186-193, 1998.
Introduction: In the radiological evaluation of living renal donors, renal ultrasonography, iv urography and renal conventional angiography are routinely performed. Transplantation may be made difficult by presence of accessory vessels and prehilar branches. The choice of kidney would then be affected.
Helical CT angiography is less invasive and less costly than conventional angiography. MR angiography is also less invasive and less expensive. Some researches have recommended use of 3-dimensional fourier transformation phase contrast magnetic resonance angiography.
Conclusions : For evaluating the arterial anatomy of living renal donors, helical C.T. angiography is superior to 3-D fourier transformation phase contrast MR angiography. Helical CT angiography is emerging as the investigation of choice for evaluating living renal donors. In addition to imaging vessels one can also study the parenchyma and the collecting system.
The study demonstrates a modest advantage of CT over MR angiography.
