In addition to Doppler ultrasound, what other imaging tool is often used for the Proximal ICA evaluation?

The use of MRA (Magnetic Resonance Angiography) in the evaluation of the Proximal Internal Carotid Artery (ICA) complements Doppler ultrasound by providing detailed images of blood vessels and blood flow without exposing the patient to ionizing radiation. MRA leverages the magnetic properties of hydrogen atoms in the body and can effectively visualize vascular structures, making it particularly useful for detecting stenosis or occlusion in the ICA.

MRA not only offers a non-invasive method to assess vascular conditions but also provides advantages in cases where ultrasound may have limitations, such as poor acoustic windows or when vascular artifacts are present. Therefore, employing MRA alongside Doppler ultrasound enhances diagnostic accuracy and helps in creating a comprehensive assessment of the proximal ICA.
