MRI

Magnetic Resonance Imaging; an imaging technique that uses strong magnetic fields and radio waves to create detailed images of organs and tissues.

Principle of MRI

MRI aligns protons in the body's water molecules with a magnetic field, then applies radio waves, allowing the protons to emit signals that are captured to create images.

Applications of MRI in Neurology

Used to visualize the brain and spinal cord, detect lesions, tumors, stroke, inflammation, and assess brain activity.

Applications of MRI in Endocrinology

Imaging of endocrine glands such as the pituitary, adrenal glands, and sometimes the thyroid to detect tumors or abnormalities.

Advantages of MRI

High soft tissue contrast, no ionizing radiation, and ability to obtain images in multiple planes.

Disadvantages of MRI

Can be expensive, time-consuming, unsuitable for some metallic implants, and may not be comfortable for claustrophobic patients.

CSF Analysis

A procedure to analyze cerebrospinal fluid for diagnosing neurological conditions, performed via lumbar puncture.

Cerebrospinal Fluid (CSF)

A clear, colorless fluid surrounding the brain and spinal cord, providing cushioning and waste removal.

CSF Analysis Applications

Used to diagnose infections, inflammatory disorders, subarachnoid hemorrhage, Guillain-Barré Syndrome, and certain neurological malignancies.

Lumbar Puncture Procedure

Involves inserting a needle into the spinal canal to collect a sample of cerebrospinal fluid.
