Post-processing techniques for aortic computed tomography angiography

Aortic diseases, such as acute intramural hematoma, acute aortic dissection and acute penetrating aortic ulcer are life-threatening disorders. Aortic computed tomography angiography can be helpful not only for pre-surgical planning but also for the follow-up evaluation. The volume-rendering technique (VR) and multiplanar reconstruction technique (MPR) are post-processing techniques within aortic CTA examination. The techniques of axial section and MPR can make accurate diagnosis, and the technique of VR is useful in pre-surgical plan.
