cannot discriminate between the intima and media layers because of
insufficient axial resolution. Therefore an elevated CIMT may be the result
of an increased intima layer from atherosclerosis, an increased media layer
due to vascular hypertrophy as seen in hypertension, or both. For this
reason, some researchers argue that CIMT, when measured in the absence of
intrusive plaque, should be considered as a marker of early arterial wall
changes rather than as a true surrogate for atherosclerosis.
