Carotid Doppler
Ultrasound with Doppler for carotid plaque and stenosis.
What is Carotid?
Ultrasound with Doppler for carotid plaque and stenosis.
How it works: A handheld transducer emits sound waves into the neck, which bounce off the carotid arteries and return echoes. The computer processes these echoes into images and uses Doppler to measure blood flow velocity and direction.
Common Uses of Carotid
Stroke risk assessment
Evaluates carotid artery narrowing that could increase stroke risk
Post-surgical monitoring
Checks for restenosis after carotid endarterectomy or stenting
Atherosclerosis detection
Identifies plaque buildup and vessel wall changes
Advantages
- ✓Noninvasive or minimally invasive
- ✓Widely available in centers
- ✓Guides management
- ✓No radiation exposure
- ✓Real-time imaging capability
Limitations
- ⚠Limited by operator or motion
- ⚠May need contrast or prep
- ⚠Not perfect specificity
- ⚠Limited visualization of intracranial vessels
- ⚠Less accurate in calcified vessels

⚖️Carotid vs CT
Related Imaging Modalities
Combine with CT/MRI/US for complementary detail. CT angiography provides better detail of calcified plaque, while MRI can visualize vessel walls without contrast.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.
