Fig. 2From: Prenatal evaluation of fetal atrioventricular valves by real-time 4D volume imaging with electronic matrix probeThe 4D rendered image of the atrioventricular valves (mitral and tricuspid) retrieved by RT 4D volume imaging combine with surface mode in a normal fetus of 25 gestational weeks. The RT 4D image can clearly show the mitral valve with two leaflets and tricuspid valve with three leaflets during systole. There is no artifact on the B and C planes. LA, left atrium; LV, left ventricle; MV, mitral valve; RA, right atrium; RV, right ventricle; TV, tricuspid valveBack to article page
