Technical characteristics, acquisition modality and data representations as well as examination protocols and main clinical applications of spiral CT angiography (CTA) are described. The different methods of 2D (MPR, CPR) and 3D (SSD, MIP) data display and their advantages and limitations were investigated. We describe the examination technique representing an important tool to achieve good image quality and to make the correct diagnosis. The clinical effectiveness and the main applications in the body were studied. CTA already has a clinical role for arterial system study, while it is less indicated in the venous system because good and continuous contrast agent opacification is difficult to obtain. In our preliminary experience, CTA can be considered an effective alternative to DSA in the assessment of vascular conditions because it is easier to perform, more rapid and less invasive. |
