CT Angiography and 3D Imaging: Current State of the Art

The rapid evolution of MDCT provides the radiologist with unprecedented capabilities to acquire high-resolution CT datasets. The development of 64-slice MDCT scanners provides the capability for subsecond data acquisition of isotropic datasets. Many now are recognizing that these datasets represent far more than just a stack of images -- they represent a volume of data that needs to be analyzed as a volume in what is commonly called volume visualization. Within this term lies a range of capabilities spanning the gamut from 3D imaging to CT angiography to virtual imaging. Applications such as CT angiography (CTA), virtual colonoscopy, and 3D orthopedic imaging are becoming more mainstream, and new applications like coronary CTA and runoff studies promise to be the next frontier in CT scanning. This course addresses the principles, exam techniques, and clinical applications in 3D imaging and CT angiography.
