LOINC description : The modified Simpson method is commonly used for volume measurements in 2D cardiac
imaging. It uses the biplane method of disks to measure left ventricular volume, meaning
that the total volume is calculated by adding together the two-dimensional area measurements
of the series of circular or elliptical slices that, taken as a whole, represent the
ventricle. [PMID: 16376782] The volume measurements can then be used in calculations
of other parameters related to cardiac function, including ejection fraction, cardiac
output and cardiac index.;
