title: Helical CT angiography. A diagnostic problem solving technique.
abstract: We describe a technique for making computed tomography (CT) angiographic studies more practical and workable. True CT angiography can be performed with arterial contrast injection combined with helical CT technique. Detailed angiographic images can be obtained; reconstructed images are aided by the helical technique, and other special studies can also be performed.
