Aortic size and diameter index calculator
Explore aortic measurements and indexing, with acquisition guidance and the reference methods available in the tool.
Method
Indexed aortic diameter = diameter ÷ BSA
Use the measurement units shown below. Some fields apply only to a selected method or condition; follow the interactive tool’s method choices. The interactive tool keeps missing measurements incomplete and provides its method-specific results and reference context.
