12. Per The Mayo Clinic. What are MRI's used for - bolding added for categorization

MRI of the brain and spinal cord
MRI is the most frequently used imaging test of the brain and spinal cord. It's often performed to help diagnose:
Aneurysms of cerebral vessels.
Conditions of the eye and inner ear.
Multiple sclerosis.
Spinal cord conditions.
Stroke.
Tumors.
Brain injury from trauma.
A special type of MRI is the functional MRI of the brain, also known as fMRI. It produces images of blood flow to certain areas of the brain. Functional MRI can be used to examine the brain's anatomy and show which parts of the brain are handling critical functions, language and movements. This information can help guide decisions when considering someone for brain surgery.
Functional MRI also can check for damage from a head injury or from conditions such as Alzheimer's disease.
MRI of the heart and blood vessels
MRI that focuses on the heart or blood vessels can check:
Size and function of the heart's chambers.
Thickness and movement of the walls of the heart.
Extent of damage caused by heart attacks or heart disease.
Structural problems in the aorta, such as aneurysms or dissections.
Inflammation or blockages in the blood vessels.
MRI of other internal organs
MRI can check for tumors or other irregularities in many organs in the body, including the following:
Liver and bile ducts.
Kidneys.
Spleen.
Pancreas.

Joint issues caused by traumatic or repetitive injuries, such as torn cartilage or ligaments.
