The cardiothoracic ratio (CTR) is used on Computed Tomography (CT) by living individuals and is considered to be a reliable indicator of cardiomegaly, with a threshold of 0.5.

CTR alone cannot be used to distinguish between normal heart weight and increased heart weight on PMCT. A new formula has been developed that includes age, gender and BMI. Dilatation of the cardiac chambers on CT, a finding not associated with cardiomegaly, is subjectively assessed and can influence CTR. The newly proposed formula excludes this subjective assessment and proposes a cut-off value of 32 for the diagnosis of cardiomegaly.
