What examinations may be performed to identify a lesion of the common carotid artery?

Several examinations can be performed to identify a lesion of the common carotid artery. Here are some of the commonly used tests:

1. Physical Examination: The healthcare provider will examine the neck for any visible signs of swelling, tenderness, or asymmetry. They may also listen for any abnormal sounds, such as bruits, which can indicate a narrowing or blockage of the artery.

2. Carotid Duplex Ultrasound: This non-invasive ultrasound examination uses sound waves to create images of the carotid arteries and assess blood flow. It can identify狭窄, aneurysms, and other abnormalities in the carotid artery.

3. Computed Tomography Angiography (CTA) of the Neck: This imaging technique combines X-rays with contrast dye to create detailed images of the carotid arteries and surrounding structures. It can detect lesions, such as plaques, calcifications, and dissections.

4. Magnetic Resonance Angiography (MRA) of the Neck: Similar to CTA, MRA utilizes magnetic fields and contrast agents to produce high-resolution images of the carotid arteries. It can be particularly useful in detecting soft tissue lesions and abnormalities adjacent to the arteries.

5. Magnetic Resonance Imaging (MRI) of the Head and Neck: This examination provides detailed cross-sectional images of the carotid arteries and their relationship to nearby structures. It can help detect lesions, masses, or other abnormalities that may be affecting the carotid arteries.

6. Angiography: This invasive procedure involves injecting contrast dye directly into the carotid artery and taking X-ray images. It provides detailed visualization of the carotid artery and can identify lesions, obstructions, and vascular abnormalities. However, it carries a slightly higher risk compared to non-invasive examinations.

The choice of examination will depend on the individual patient's condition, symptoms, and suspected underlying pathology. Your healthcare provider will recommend the most appropriate examination based on your specific situation.
