The pulmonary annulus is a morphology measurement. It helps describe congenital or post-intervention anatomy and provides context for stenosis, regurgitation, or prosthesis planning.
Use a zoomed view, avoid oblique cuts, and compare with prior studies when valve morphology or RVOT geometry has changed.
