Três importantes normas que afetam o dia a dia do Ecocardiografista:

1- Não utilizar o Zoom na IMT

2- Apresentar no corte a bifurcação

3- Medir na posterior 1 cm antes da bifurcação e não 2 cm.

To measure CIMT, each common carotid artery (CCA) was identified along its longitudinal axis, using standard brightness and contrast. IMT was calculated automatically using the Medical Imaging Applications software (MIA, Coralville, Iowa, USA), with analysis on three electrocardiographically gated cardiac cycles. Only the proximal far wall of the CCA (1 cm proximally to the carotid bifurcation, with 1 cm length) was measured, and mean and maximum values for each CCA were obtained.

IMT measurement at a distance of at least 5 mm below the distal end of CCA (IMT could also be measured at the carotid bifurcation and internal carotid artery bulb, but the values should be given separately
