During a TEE, a flexible probe with a transducer built into it is placed in the esophagus - the tube that connects the back of the mouth to the stomach.īecause the esophagus is directly behind the heart, clearer, detailed ultrasound images can be created. Or your provider may choose to perform another type of echocardiography called a transesophageal echocardiogram (TEE). The transducer emits sound waves that bounce off different parts of the heart, creating an ultrasound image. A TTE involves moving an instrument called a transducer across the chest. Your provider may choose to perform a traditional echocardiography called transthoracic echocardiogram (TTE). MRA uses technology similar to MRI to evaluate the arteries in the neck and brain but may include an injection of a contrast material into a blood vessel.Įchocardiography. These procedures, which use a strong magnetic field, can generate a composite 3D view of the brain. Magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA).Unlike a carotid ultrasound, a CTA scan can evaluate blood vessels in the neck and head. CTA scanning uses X-rays similar to a standard CT scan but may also involve injection of a contrast material into a blood vessel. CT scanning of the head uses X-ray beams to assemble a composite 3D look at the brain or evaluate the arteries in the neck and brain. Computerized tomography (CT) or computerized tomography angiography (CTA) scanning.After the sound waves pass through the tissue and back, your provider can analyze images on a screen to look for narrowing or clotting in the carotid arteries. A wand-like device (transducer) sends high-frequency sound waves into the neck. If your provider suspects that the carotid artery may be the cause of your TIA, a carotid ultrasound may be considered. Your provider may check for risk factors of a stroke, including high blood pressure, high cholesterol levels, diabetes and in some cases high levels of the amino acid homocysteine. Or your provider may use an ophthalmoscope to look for cholesterol fragments or platelet fragments (emboli) in the tiny blood vessels of the retina at the back of the eye. A whooshing sound (bruit) may indicate atherosclerosis. Your provider may use a stethoscope to listen to the carotid artery in your neck. The provider will test your vision, eye movements, speech and language, strength, reflexes, and sensory system.
Your provider will perform a physical exam and a neurological exam.
