Left ventricular Ejection fraction by US.2D+Calculated by modified Simpson method
LV EF US.2D+mod Simpson
Definition
- 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.
