Brain MRI Sequence Overview

These flashcards cover key concepts, terms, and anatomical structures related to clinical indications and imaging of the brain.

Transient Ischemic Attack (TIA)

A temporary period of symptoms similar to those of a stroke.

Cerebrovascular Accident (CVA)

Medical term for stroke, which refers to a sudden loss of brain function.

Multiple sclerosis (MS)

An autoimmune disease that affects the central nervous system, leading to demyelination.

Corpus Callosum

A large bundle of neural fibers that connects the left and right cerebral hemispheres.

Anatomy of the brain

Includes structures such as the cerebrum, cerebellum, brain stem, and various lobes.

Gray matter

Regions of the brain primarily composed of neuronal cell bodies.

White matter

Regions of the brain composed mainly of myelinated axons.

Acoustic Neuroma

A noncancerous tumor on the vestibulocochlear nerve that can affect hearing and balance.

Alzheimer's disease

A progressive neurodegenerative disease that causes memory loss and cognitive decline.

Imaging Sequences

Different MRI techniques used to reveal specific details about brain structures and pathology.

Hydrocephalus

An accumulation of cerebrospinal fluid within the ventricles of the brain.

Demyelinating disease

Disorders characterized by damage or loss of myelin, leading to impaired nerve function.

Epidural Hematoma

Bleeding between the skull and the outer covering of the brain, often due to trauma.

Pituitary Adenoma

A benign tumor of the pituitary gland that can affect hormone production.

Hippocampus

A brain structure integral to memory formation and spatial navigation.

Imaging planes

Anatomical orientations in imaging, such as sagittal, axial, and coronal.

T2 FLAIR

An MRI sequence that helps visualize edema and lesions, especially in multiple sclerosis.

Vestibulocochlear nerve (VIII)

The cranial nerve responsible for hearing and balance.

Optic neuritis

Inflammation of the optic nerve, often associated with multiple sclerosis.

Dynamic contrast-enhanced sequences

MRI techniques that use contrast agents to enhance images of vascular structures.
