  2. Carotid ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Carotid_ultrasonography

    Carotid ultrasonography is an ultrasound-based diagnostic imaging technique to evaluate structural details of the carotid arteries. Carotid ultrasound is used to diagnose carotid artery stenosis (CAS) and can assess atherosclerotic plaque morphology and characteristics. [1] Carotid duplex and contrast-enhanced ultrasound are two of the most ...

  3. Doppler ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Doppler_ultrasonography

    Absence of the portal system in a first trimester case associated with hygroma and aorto-umbilical fistula. (A): Transverse plane of the upper abdomen with color Doppler applied, showing umbilical cord insertion, stomach, the prominent hepatic artery and no afferent liver venous perfusion; (B): midsagittal plane reconstructed from a three-dimensional volume acquisition were the crown-rump ...

  4. Common carotid artery - Wikipedia

    en.wikipedia.org/wiki/Common_carotid_artery

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

  5. 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.

  6. Hollenhorst plaque - Wikipedia

    en.wikipedia.org/wiki/Hollenhorst_plaque

    This is a test commonly performed; however, much like the carotid Doppler ultrasound, a negative test does not rule out the heart as a potential source of the retinal embolus. This is not part of the standard workup due to the limited research available, but may be ordered for certain patients at the discretion of the primary care physician. [1]

  7. Carotid artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_stenosis

    The internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis, an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow. [3] [4]

  8. Doppler echocardiography - Wikipedia

    en.wikipedia.org/wiki/Doppler_echocardiography

    Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.

  9. Vascular surgery - Wikipedia

    en.wikipedia.org/wiki/Vascular_surgery

    Carotid ultrasound. Carotid endarterectomy. Vascular surgeons are responsible for treating extracranial cerebrovascular disease as well as the interpretation of non-invasive vascular imaging relating to extracranial and intracranial circulation such as carotid ultrasonography and transcranial doppler.
