Angio-CT was performed following a pre-established protocol. All exams were performed using the same 320-detector row device equipped with software for ultra helical scan mode. The arterial-phase, con
the trigger threshold level was set at 150 HU to achieve a greater contrast concentration in the descending aorta. 130 patients will be analysed, exam will be performed only one time, two groups (A 65

Inclusion criteria
Inclusion criteria: Both genders; age more than 18 years; aortic Angio-CT performed with the Aquillion One device at Hospital das Clínicas by predefined protocol; acceptance of terms and exams protocol
Exclusion criteria
Exclusion criteria: Exclusion criteria were previous surgery of the descending aorta, individuals with diseases liable to affect the results due to the presence of collateral circulation (Takayasu’s arteritis, coarctation of the aorta), individuals with paraplegia or tetraplegia, known allergy to the radiological contrast medium, concomitant inclusion in another study in which its protocol could interfere, aortic intramural hematoma and penetrating ulcer of the aorta, refusal to participate and flawed aorta opacification due to technical reasons
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Adamkiewicz artery identification in AngioCT in percentage and between groups comparison. Expect minimum of 60% of identification and better identification among non aortopatics.;Adamkiewicz artery identification in group A was 78,7% was higher than the group B (40,7%) with p<0,0001 | — |
Secondary
| Measure | Time frame |
|---|---|
| Adamkiewicz artery laterality and origin (percentage). Expect more identification in the left side and between T9 and T12;Adamkiewicz artery laterality was 73,6% left side and 26,4% right side. More frequent between T9 and T12. | — |
