Comparación cuantitativa ex vivo e in vivo de las dimensiones del lumen medidas por tomografía de coherencia óptica y ecografía intravascular en arterias coronarias humanas

In fixed human coronary arteries, both IVUS and OCT overestimated the lumen area compared with histomorphometry. In vivo the lumen dimensions obtained using IVUS were larger than those obtained using OCT, with or without occlusion. Moreover, the OCT image acquisition technique (i.e. with or without occlusion) also had an impact on lumen measurement.
