The largest part of the brain responsible for higher functions like thinking, learning, and memory. It is divided into two hemispheres.

The second largest part of the brain located at the back of the head. It helps with movement, balance, and coordination.

The lower part of the brain that connects the cerebrum and cerebellum to the spinal cord. Essential for vital functions like breathing, heart rate, and sleep.

The outer layer of the cerebrum, which contains nerve cell bodies. It's responsible for processing sensory information and controlling movement.

The inner part of the cerebrum, containing nerve fibers that connect different parts of the brain. It helps relay information.

A specialized imaging technique that uses magnetic fields and radio waves to create detailed images of the brain. It is valuable for diagnosing neurological conditions.

The study of the brain and nervous system. It includes how the brain functions, its structure, and how it interacts with the body.

A condition often characterized by fatigue, muscle weakness, and numbness. It is a chronic inflammatory disease that damages the central nervous system.

MRI is particularly useful for detecting lesions in the back of the brain (posterior fossa), near the skull's edge, and at the base of the skull and pituitary gland area. It offers greater detail compared to CT scans.

MRI excels at visualizing blood clots and strokes. It can also be used to detect narrowing or blockages in brain blood vessels using MR angiography.

MRI can reveal the full extent of brain injuries, including diffuse axonal injury (DAI), which affects nerve fibers. Although MRI is great for soft tissue injuries, it can't show bone fractures as well as CT scans.

MRI is incredibly valuable for diagnosing multiple sclerosis, a condition that affects the nervous system. It can also help diagnose other degenerative conditions like subcortical arteriosclerotic encephalopathy and gliosis.

The patient lies flat on their back (supine) with their head first into the MRI machine (head coil). Padding is important to prevent movement and maintain image quality. A mirror within the coil can help reduce claustrophobia by allowing the patient to see out.

A sagittal localizer image helps to align slices parallel to the corpus callosum, a central structure in the brain. This image covers the entire brain from the neck junction to the top (vertex) and includes all brain lobes.

A sagittal localizer helps to align slices parallel to the brainstem, a vital part of the brain. It covers the entire brain from the neck junction to the top (vertex) and includes all sides and lobes.

An axial localizer helps to align slices parallel to the falx cerebri, a membrane dividing the brain. This image covers the entire brain from the neck junction to the top and includes all sides and lobes.
