This study showed, that by using a commercial 3D post processing software (3 Mensio®, semiautomatic centerline analysis) in comparison to conventionally evaluated 2D-CTA reconstructions (MPRs) on the basis of thoracic aortic aneurysms a lesser intra- and interindividual variability could be achieved. In addition, intermodal in nearly all 3D measurements more homogeneous values (less variance) and a clear tendency towards higher values (greater distances) compared to the measurements on the 2D reconstructions could be demonstrated. A dependence of the variability of the experience of the examiner could not be detected.
