By analyzing these echoes, ultrasound technology generates detailed images of the carotid artery and surrounding structures.
One of the primary ultrasound techniques used for detecting carotid artery blockage is carotid Doppler ultrasound. This technique combines traditional ultrasound imaging with Doppler technology, which allows for the assessment of blood flow through the carotid arteries.
During a carotid Doppler ultrasound, the technician will apply gel to the skin over the carotid artery and use the transducer to capture images. They will evaluate the blood flow velocity, measure the size of the plaque that may be causing blockage, and assess the degree of stenosis or narrowing in the carotid artery.
Characteristic findings associated with a blocked carotid artery on ultrasound can include the presence of plaque, which appears as a localized thickening or narrowing of the artery walls. The degree of stenosis, or how much the artery is narrowed, can be measured and categorized. Other important features that may be visualized include disturbances in blood flow patterns, such as turbulence or increased velocity, indicating the presence of an obstruction.
Early detection of carotid artery blockage through ultrasound imaging is crucial for initiating appropriate treatment and preventing complications such as stroke. By identifying the characteristic ultrasound findings associated with a blocked artery, healthcare professionals can determine the severity of the blockage and develop an effective management plan tailored to each patient’s needs.
