Left atrial End-systolic volume by US.2D+Calculated by modified Simpson method

Active

Term Description

The modified Simpson method is commonly used for volume measurements in 2D cardiac imaging. It uses the biplane method of disks, 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 chamber being measured.
