  2. Carotid ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Carotid_ultrasonography

    Carotid ultrasound is a low-cost, noninvasive, and accurate diagnostic imaging modality used to evaluate diseases of the carotid arteries. [2] It is most often used to diagnose carotid artery stenosis, a form of atherosclerosis , and has the capability to assess plaque morphology and characteristics. [ 1 ]

  3. Digital subtraction angiography - Wikipedia

    en.wikipedia.org/wiki/Digital_subtraction...

    Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...

  4. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.

  5. External carotid artery - Wikipedia

    en.wikipedia.org/wiki/External_carotid_artery

    The condition and health of the external carotid arteries is usually evaluated using Doppler ultrasound, CT angiogram or phase contrast magnetic resonance imaging (PC-MRI). Typically, blood flow velocities in the external carotid artery are measured as peak systolic velocity (PSV) and end diastolic velocity (EDV). [4]

  6. Carotid endarterectomy - Wikipedia

    en.wikipedia.org/wiki/Carotid_endarterectomy

    The carotid artery is the large vertical artery in red. The blood supply to the common carotid artery starts at the arch of the aorta (left) or the subclavian artery (right). The common carotid artery divides into the internal carotid artery and the external carotid artery. Plaque often builds up at that division, and a carotid endarterectomy ...

  7. Intima–media thickness - Wikipedia

    en.wikipedia.org/wiki/Intima–media_thickness

    The carotid artery is the usual site of measurement of IMT and consensus statements for carotid IMT have been published for adults [12] and children. [13] Often, carotid IMT is measured in three locations: in the common carotid artery (typically at one cm proximal to the flow divider), at the bifurcation, and in the internal carotid artery.

  8. Vascular surgery - Wikipedia

    en.wikipedia.org/wiki/Vascular_surgery

    The most common of cerebrovascular conditions treated by vascular surgeons is carotid artery stenosis which is a narrowing of the carotid arteries and may be either clinically symptomatic or asymptomatic (silent). Carotid artery stenosis is caused by atherosclerosis whereby the buildup of atheromatous plaque inside the artery causes narrowing.

  9. Atheroma - Wikipedia

    en.wikipedia.org/wiki/Atheroma

    Arterial ultrasound, especially of the carotid arteries, with measurement of the thickness of the artery wall, offers a way to partially track the disease progression. As of 2006, the thickness, commonly referred to as IMT for intimal-medial thickness, is not measured clinically though it has been used by some researchers since the mid-1990s to ...
