Which structures are typically examined in a carotid ultrasound?

The carotid ultrasound primarily focuses on assessing the carotid arteries, which are crucial blood vessels located in the neck that supply blood to the brain, face, and neck. This examination involves looking for plaque buildup or blockages within these arteries, which can lead to an increased risk of stroke or other cardiovascular issues. By evaluating the condition of the carotid arteries and the surrounding tissues, healthcare professionals can determine the presence of atherosclerosis or other vascular abnormalities.

The other structures mentioned, such as the jugular veins, aorta, and subclavian arteries, are not the primary focus of a carotid ultrasound. While they may be important in the broader context of vascular studies, the carotid ultrasound specifically targets the carotid arteries and any pathologies associated with them. Therefore, the correct choice accurately reflects the primary intention and scope of a carotid ultrasound examination.
