Going superior to inferior and clockwise
1st stop Aorta LA
2nd Stop
4 chamber

Axial images through the 4 chambers at the level of the A-V valves during diastole (mitral valve open) enables an approximate volume evaluation of the chambers. The atria are approximately the same volumes, and are about 1/3 the volume of the ventricles. The right ventricle (RV) is about 2/3 the volume of the left ventricle (LV)

Clockwise Rotation

Axial images through the body of the right atrium (RA) at the level of the tricuspid valve shows a linear dimension of 4.2cms (normal up to about 5cms)
