A specialized imaging technique that uses strong magnetic fields and radio waves to create detailed images of the brain and other soft tissues.

MRI is exceptionally effective in diagnosing a variety of conditions affecting the brain, including multiple sclerosis, subcortical arteriosclerotic encephalopathy, gliosis, and syrinx.

The patient is positioned lying on their back, with their head positioned first in the scanner, ensuring proper alignment and comfort.

A series of images are acquired to create a comprehensive view of the cranial region from the superior to inferior, encompassing the temporal lobes, and the occipital to frontal lobes.

Flair images are useful for identifying areas of edema or inflammation, particularly effective in detecting plaques in Multiple Sclerosis.

A series of images are acquired to create a comprehensive view of the cranial region from the superior to inferior, encompassing the temporal lobes, and the occipital to frontal lobes.

A series of images are acquired to create a comprehensive view of the cranial region from the superior to inferior, encompassing the temporal lobes, and the occipital to frontal lobes.

Different types of MRI sequences are used to optimize image contrast and detail, depending on the specific clinical needs.

The central nervous system includes the brain and spinal cord, which are responsible for processing information and controlling bodily functions.

The peripheral nervous system is a network of nerves that branch out from the brain and spinal cord to connect to different parts of the body.

The cerebrum, the largest part of the brain, is responsible for higher-level functions like thinking, memory, and language. It has two hemispheres connected by the corpus callosum.

The cerebellum is the second largest part of the brain located in the posterior cranial fossa. It's crucial for coordination, balance, and motor control.

The brain stem is a vital part of the brain connecting the cerebrum to the cerebellum and spinal cord. It controls essential functions like breathing, heart rate, and sleep.

MRI is a superior imaging technique for detecting brain tumors, especially those located at the base of the skull or in the pituitary fossa.

MRI is crucial for diagnosing both hemorrhagic (bleeding) and ischemic (blockage) strokes. MR angiography can even detect thrombosis or stenosis (narrowing of blood vessels).

MRI offers better assessment of trauma to the brain, including diffuse axonal injury, compared to CT, which shows only the extent of the initial injury.
