Stroke
What is a Stroke
Strokes are the fifth leading cause of death among Americans. They are caused by either a clot that blocks blood flow to a region of the brain or by a blood vessel rupturing. SPECT imaging, which measures blood flow throughout the brain, has proven to be helpful tool in the evaluation and management of cerebrovascular diseases, an underlying cause of stroke.
Common Symptoms
According to the CDC, common signs of stroke in Men and Women include:
Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body
Sudden confusion, trouble speaking, or difficulty understanding speech
Sudden trouble seeing in one or both eyes
Sudden trouble walking, dizziness, loss of balance, or lack of coordination
Sudden severe headache with no known cause
Impacted Areas of the Brain
SPECT helps to depict areas of ischemia (inadequate blood supply) with greater accuracy in patients who have had a stroke and/or transient ischemic attack (TIA). SPECT is also helpful in differentiating stroke from complex brain conditions that may have overlapping symptoms, and identify and rule out dual diagnoses in the event the stroke was caused by head trauma or fall.
