STOISA, Daniela; GALIANO, Fabrizzio E.; QUARANTA, Andrés  e  VILLAVICENCIO, Roberto L.. 64-Multidetector row CT for the Renal Vascular Study. Rev. argent. radiol. [online]. 2009, vol.73, n.1, pp.045-050. ISSN 1852-9992.

Purpose: To show the wide range of anatomical vascular variants, arterial and venous, that can be seen in the angiographic renal study using 64-multidetector-row computed tomography (64-MDCT), due to its importance in an eventual surgical planning. Material and Methods: We have evaluated retrospectively 26 studies that have been done using a 64 channels Philips Brilliance CT scanner. We have obtained non enhanced and both in arterial and venous enhanced sequences. For the injection of the contrast material we have used a double head injector bomb. The arterial phase was acquired using the bolus track technique. The raw data has then been post processed in a 190P Philips Brilliance workstation in a mean time of 30 minutes. The reconstructions have been obtained both with MIP and volumetric technique. Conclusion: The renal vascular study has importance for the surgical planning in cases of parcial nephrectomies or laparoscopic nephrectomies as well as in renal transplant. This makes the 64-MDCT a very useful non invasive imaging tool due to its high accuracy similar to digital angiography.
