Developmental phase
Assessment
Primary outcomes
Comparison of aorta diameters on non-contrast CT images measured by a medical doctor with the assistance of the prototype AI software and those on contrast enhanced CT images assessed by medical doctors (ground truth).
Key secondary outcomes
1. Comparison of aortic diameter measurement solely by a medical doctor or by the AI software using non-contrast CT and ground truth.
2. Comparison of aortic diameter measurements solely by the AI software using contrast enhanced CT and ground truth.
3. Comparison of aortic diameter measurement by maximal short diameter method and ground truth.
4. Influence of the AI software on interobserver variance.
5. Influence of the AI software on the reading time.

Key inclusion criteria
Patients who are scheduled for CT scan to examine aortic disease, especially thoracic aortic aneurysm or to follow-up thoracic aortic aneurysm.
Key exclusion criteria
1) Suboptimal image quality of the thoracic aorta limiting evaluation of the aortic diameter.
2) Under 22 years of age at the time of obtaining consent.
3) With allergy to iodine contrast media.
4) With active asthma.
5) With Grade 4 or higher renal dysfunction (eGFR less than 30 ml/min/1.73m2).
6) Others who are judged by the principal investigator to be unsuitable as subjects.
