Stroke occurs when blood flow to the brain is interrupted by a blockage or a rupture in an artery, depriving brain tissue of oxygen. It is the fourth leading cause of death in the United States and a leading cause of disability. Close to 800,000 Americans suffer a stroke each year. Most suffer ischemic stroke, which occurs when blood flow to the brain is obstructed by a clot in a blood vessel. Fortunately, ischemic stroke can be treated effectively with a tissue plasminogen activator (tPA), a drug that if administered within three hours of the first signs of stroke dissolves a clot to improve blood flow back to the affected part of the brain. Unfortunately, it can take an hour after a stroke patient arrives in the ED to receive treatment because of the time needed to determine which kind of stroke the patient is having. If only there was a faster way to diagnose stroke patients with a readily available CT scanner.
A mobile stroke unit (MSU) is a specialized ambulance or other emergency medical vehicle that is equipped with a CereTom® CT (computed tomography) scanner. The mobile unit with diagnostic CT imaging capabilities allows the team onboard to quickly assess whether a patient is having a stroke caused by a blood clot or hemorrhage. If it is determined to be caused by a blood clot, the clot-buster tPA (tissue plasminogen activator) can be administered immediately.
Samsung’s CereTom is the only true portable CT scanner available on the market today for this application and is the critical component in a mobile stroke unit. All existing Mobile Stroke Unit Programs are equipped with a CereTom and demand continues to grow worldwide for this exciting technology.
