Three-dimensional helical CT angiography.
CT angiography can accurately depict vascular lesions in less time, with less patient morbidity, and at a lower cost than conventional angiography. Meticulous attention to scan technique is required for achieving diagnostic images. Regardless of the three-dimensional rendering techniques employed, a review of the original axial sections is always required to ensure the detection of any unsuspected parenchymal lesions present and to exclude inaccuracies in segmentation and three-dimensional rendering.
