Stroke Diagnosis & Treatments

Stroke Diagnosis

Our team performs a range of diagnostic procedures for comprehensive stroke diagnosis. These include:

CT, CT Angio & CT Perfusion

A CT scan is one of the most effective imaging modalities to diagnose a stroke. It is usually one of the first tests performed when we do a stroke evaluation, particularly when an acute stroke occurs in the emergency room setting. We have the ability to perform CT angiography (CTA) for evaluation of acute ischemic stroke as well as CT perfusion for rapid imaging and delineation of areas of the brain that may be salvaged by intervention from the parts that are irrevocably damaged (infarcted).

3 Tesla MRI, MRA & MR Perfusion

Though magnetic resonance imaging (MRI) takes longer than a CT scan, this technology is one of the most effective ways to determine whether a stroke is hemorrhagic or ischemic. We utilize a highly advanced 3 Tesla MRI scanner, which provides extremely high resolution anatomic detail. This scanner’s increased spatial resolution allows for very high-quality vascular imaging, allowing us to perform 3 Tesla MR angiograms (MRA) instead of invasive interventional studies using a catheter. We also have the ability to perform perfusion weighted imaging to map blood flow through brain tissue.

Stroke Treatments

Treatments for stroke patients admitted to the hospital may include:


Intravenous (IV) tissue plasminogen activator (tPA) treatment is used to manage acute ischemic stroke in the emergency room. Administered through an IV in the arm, tPA dissolves blood clots and improves blood flow to the part of the brain being deprived of blood flow. Generally, tPA must be administered within 3 hours of the stroke in order to improve chances of recovery.

Endovascular Clot Removal

Known as a mechanical thrombectomy, this surgical procedure involves removing a blood clot by using a device called a stent retriever to grab the clot at the site of the blocked blood vessel in the brain. The stent retriever is placed inside a catheter threaded through an artery in the groin up to the blocked artery in the brain. This procedure should be done within 6 hours of acute stroke symptoms, and only after a patient first receives IV tPA.

Aneurysm Clipping & Coiling

Brain aneurysms may be treated using open surgical clipping or endovascular coiling. In a clipping procedure, the surgeon places a clip across the aneurysm where it arises from the blood vessel to prevent blood from entering the aneurysm. Coiling is performed by inserting several catheters into the blood vessels and navigating to the vessels of the brain and into the aneurysm. Microscopic coils are then wound into the aneurysm to prevent blood flow into the aneurysm.

Carotid Artery Stenting

bring blood to your brain and face are called the carotid arteries are blood vessels that bring blood to your brain. If they become blocked with plaque (a fatty buildup inside the vessel), blood flow to the brain may be reduced, and a stroke can occur as a result. During the carotid artery stenting procedure, a catheter with a very small balloon attached is directed to the area of artery blockage. The balloon is inflated to open up the artery and restore proper blood flow to your brain. A stent (a wire mesh tube) may also be placed in the artery to help keep it open.

Carotid Endarterectomy

Similar to carotid artery stenting, this procedure removes fatty deposits blocking one of the two carotid arteries, the main supply of blood for the brain. The surgery can help people who have already had a stroke or experienced the symptoms of a stroke and have severe blockage. Patients who have already had transient or mild stroke symptoms due to moderate blockage of the carotid arteries, this procedure can reduces the long-term risk of stroke or death.
