Abstract

Purpose
Establish normative reference values for thoracic aortic diameter (AD) in participants in the National Lung Screening Trial (NLST).

Methods
Thoracic AD on 322 prevalence CTs was recorded at the sinotubular junction (STJ), mid-ascending (MA), transverse arch (TA), mid-descending (MD), and diaphragmatic hiatus (DH).

Results
Mean AD (cm) and upper limits of normal for men and women were recorded for at each location. Smoking did not correlate with AD. Age, gender and body surface area (BSA) were the most significant factors.

Conclusions
Thoracic AD reference values are reported. They do not correlate with smoking, but did for age, gender, BSA.
