Functional Magnetic Resonance Imaging
FMRI
Description
"Functional Magnetic Resonance Imaging" (fMRI) scan shows which areas of your brain are active during specific tasks by tracking blood flow changes. Doctors often order it before brain surgery or to assess damage from strokes, trauma, or neurological disorders. During the scan, you're asked to perform tasks like reading or tapping fingers. The scan highlights areas involved in movement, language, or memory. Results help guide surgical planning and support long-term care strategies for brain function and recovery.

Test Group Description
Imaging Scans Group: This group includes a variety of diagnostic imaging techniques used to visualize internal structures and organs in the body. These techniques may include X-rays, CT scans, MRI scans, ultrasound, and nuclear medicine scans.
Optimal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Normal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Alzheimer's disease (Neurodegenerative disorder leading to memory loss and cognitive decline)
Brain tumors
Concussion
Epilepsy (Neurological disorder characterized by recurrent seizures)
Pain
Parkinson's disease (Neurodegenerative disorder affecting movement)
Post-concussion syndrome (Persistent symptoms following a concussion)
Schizophrenia (Chronic mental disorder affecting cognition, emotion, and behavior)
Key Reasons For Testing
Localization of Brain Function: fMRI maps brain activity by measuring blood flow changes, identifying regions responsible for language, motor control, or memory.
Brain Disorder Diagnosis: Aids in diagnosing and monitoring disorders like stroke, epilepsy, or neurodegenerative diseases by visualizing abnormal activity.
Cognitive Research: Studies brain activation linked to cognition, emotion, and behavior.
Surgical Planning: Identifies critical areas to avoid during brain surgery.
Psychiatric Evaluation: Explores brain function in depression, schizophrenia, and anxiety to guide treatments.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
