What are the roles, advantages, and limitations of different imaging techniques in assessing carotid atherosclerotic plaque?
Multimodality imaging plays a crucial role in the evaluation of carotid atherosclerotic plaques, with each technique offering specific advantages for risk stratification and clinical decision-making.

May enhance carotid plaque risk stratification beyond stenosis; leaves open optimal advanced modality selection pending prospective validation.
. The main techniques include ultrasound imaging, X-ray imaging, magnetic resonance imaging and positron emission tomography imaging. Each technique has advantages and limitations and may be chosen depending on the availability, cost and clinical justification for its use. Common to all the imaging techniques presented here is the need for a skilled imaging professional to allow for high reliability and repeatability. While ultrasound-based imaging currently is regarded as a first line technique in clinical practice, the use of other techniques such as computed tomography angiography or magnetic resonance angiography need to be considered in the presence of significant stenosis with or without symptoms. Advancements in these two modalities, as well as in positron emission tomography imaging, are increasingly moving toward a better understanding of the risk-stratification and pre-interventional monitoring of patients at risk of plaque rupture as well as early identification of plaque development and better understanding of plaque composition (e.g. metabolic imaging).

Neumann et al. (2019) conducted a review in Carotid atherosclerotic plaque. Imaging techniques (ultrasound, X-ray, MRI, PET) was evaluated. Various imaging modalities, including ultrasound, CT, MRI, and PET, offer distinct advantages for risk-stratification, monitoring, and understanding carotid atherosclerotic plaque composition.
