Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Subjects awaiting for an aortic evaluation

Subjects already waiting for an aortic evaluation, either a first diagnostic scan or follow-up of a known aneurysm.

Each subjects will have the two CT-scans on the same day.

Group Type EXPERIMENTAL

Modified Low-dose, EKG-gated CT without contrast for the evaluation of aortic aneurysm

Intervention Type OTHER

On the same day, the subject will do :

1. Modified low-dose, EKG-gated CT without contrast
2. Usual high-dose, EKG-gated CT with contrast

Comparing aortic diameters from the two protocols.
