Medical Tests for Diagnosing Strokes
A stroke is a medical condition occurring due to anomalies in the cerebral blood vessels. Although professionals are often able to make an approximate diagnosis from observing the symptoms, it can be difficult to determine the type or cause of injury without further testing.
Strokes occur due to either a cerebral hemorrhage (bleeding in the brain) or cerebral infarction(lack of blood to the brain). As the two diseases require a completely different treatment process, imaging is vital for treatment planning. To determine the cause of a stroke medical professionals may order one of more of these tests:
Computed Tomography (CT): CT combines special x-ray equipment with sophisticated computers to produce multiple images an area of the body. Availability and access to CT scans is widespread and often provides the speediest imaging option. In the hyperacute phase, a noncontrast CT (NCCT) scan is usually ordered to exclude or confirm hemorrhage
- Computed Tomography Angiography (CTA) is a specific CT technique where a contrast material may be injected intravenously and images are obtained of the cerebral blood vessels. Blood flow can be detected at the same time using a technique called Computed Tomography Perfusion (CTP).
- Sonography: is used to collect information on blood flow velocity and obstructions using measurements of the echoes of harmless ultrasound waves
- Carotid Ultrasound examines the carotid and vertebral arteries located in the neck.
- Transcranial Doppler (TCD)- examines the arteries inside the skull
- Magnetic resonance Imaging (MRI) uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of the brain.
- Magnetic Resonance Angiography (MRA) is a type of magnetic resonance imaging (MRI) scan that specifically examines blood vessels.. It can be performed in combination with brain MRI to detect less common causes of ischemic stroke.
Even once patients return home to rehabilitate, physicians may continue to reorder new versions of these specialized images in order to gain more information over time and prevent relapse. Periodic checkups and communication with your medical team are essential to determining a medical plan as well as a creating a tailored exercise program to promote functional recovery.
RAPAEL’s smart rehab solution devices have been developed to create functional rehabilitation exercise programming for patients with nervous and musculoskeletal disorders such as stroke. The lightweight and compact equipment along with smart cloud computing allows consistent training to be carried out even at home. Training is customized based on the patient's condition, backed up with clinical trials and includes live occupational therapist support.
