Abstract

Background

The purpose of the study was to compare axial measurements of the ascending thoracic aorta on gated CT study studies with double oblique measurements and calculate the divergence between orthogonal axial and double oblique diameters of the tubular ascending aorta.

Methods

Retrospective measurements of axial and double oblique diameters were obtained in 153 consecutive patients.

Results

On average, the axial dimension exceeded the double oblique measurement.

Conclusion

Our study endorsed the subtraction of 0.58 mm from the axial diameter in order to obtain the double oblique measurement.

Keywords

CT - tubular ascending aorta - dimensions - axial - double oblique
