Ascendant Aortic Aneurysm Clinical Trial
Official title:
Low-dose, EKG-gated CT Validity for the Evaluation of Ascendant Aortic Aneurysm.
We will demonstrate the validity of measurements with a low-dose, EKG-gated CT without contrast in the ascending aorta evaluation, compared with the current Angio-CT measurements.
The actual protocol used in aorta evaluation consist of two CT-scans on the same study. The
first scan that detects calcifications is using parameters with low-dose current, non
EKG-gated and without contrast. The second scan uses iodine-contrast, EKG-gating and higher
current dose to obtain higher image quality of diagnostic value.
The study will optimize the first scan parameters and compare the measures of the aorta
diameters from the standard protocol.
By modifying the first scan parameters, we would demonstrate that the follow-up of an aortic
aneurysm can safely be made with lower radiation exposure.
