Aortic Cross-Sectional Area to Height Ratio Calculator

The Aortic Cross-Sectional Area to Height Ratio (ACAR) is a measure used to assess the size of the aorta relative to an individual’s height. It helps determine if the aorta is within a normal range. ACAR values can vary, but a higher ratio may indicate a dilated aorta. Consult a healthcare professional for a proper evaluation and interpretation of ACAR results.
