Stroke Diagnostics: Determining the Type and Cause of Stroke
Stroke Diagnostics There are two main types of strokes - ischemic and hemorrhagic. Different diagnostic tests are used to determine the specific type and cause of a stroke. An accurate diagnosis is important to guide appropriate treatment and management. Computerized Tomography (CT) Scan A CT scan, also known as a computerized axial tomography scan, is usually the first imaging test performed. It can quickly detect hemorrhages and blood clots. CT scans are able to distinguish between an ischemic and hemorrhagic stroke within minutes. They can also detect older strokes, revealing potentially underlying conditions that may have caused the stroke. Magnetic Resonance Imaging (MRI) While CT scans are effective for acute Stroke Diagnostics , an MRI provides additional diagnostic information. MRIs have a higher resolution and are more sensitive for detecting small strokes and ischemia from disrupted blood flow. They can identify clinically silent lesions and help determine the age of an...
