ECG-gating may avoid overestimating coronary volumes in 3D ICUS; hypothesis-generating for routine adoption in volumetric studies.
Does ECG-gated 3-D ICUS image acquisition alter volumetric measurements compared to nongated acquisition in human atherosclerotic coronary arteries?
ECG-gated 3-D ICUS yields significantly smaller volumetric measurements compared to nongated acquisition, highlighting the importance of gating for studies assessing small differences in vessel dimensions.
