CT angiography: principles, techniques and study optimization using 16-slice multidetector CT with isotropic datasets and 3D volume visualization.

Significant advances in computed tomography (CT) scanner technology as well as 3D imaging software and hardware have resulted in amazing improvements in CT imaging of blood vessels. CT angiography has now been incorporated into daily practice and in may cases has replaced conventional angiography. CT angiography has also resulted in new applications for CT such as coronary angiography. This article discusses the current state of the art of 3D CT angiography and reviews the literature. Extensive case examples are included.
