Multiple sclerosis (MS) is a disease in which the body’s immune system attacks the protective covering surrounding the nerves of the central nervous system. Magnetic resonance imaging (MRI) can reveal telltale scars (lesions) on the brain or spinal cord. There’s no single definitive test for MS. Diagnosis is based on symptoms, clinical evaluation, and a […]

A lesion is an area of tissue that has been damaged through injury or disease. So a brain lesion is an area of injury or disease within the brain. While the definition sounds simple, understanding brain lesions can be complicated. That’s because there are many types of brain lesions. They can range from small to […]

MRI Brain White Matter Abnormalities

Background Changes in the cerebral hemispheric white matter are detected with increasing frequency by CT and MRI among persons older than 60 years. The pathogenesis, clinical significance, and morphological substrate of these changes are incompletely understood. Patients who have such neuroimaging abnormalities are sometimes diagnosed with “Binswanger’s disease,” an eponym that has generated much confusion […]

Structural MRI provides information to qualitatively and quantitatively describe the shape, size, and integrity of gray and white matter structures in the brain. Broadly speaking, MRI signal varies across tissue types because gray matter contains more cell bodies (e.g., neurons and glial cells) than white matter, which is primarily composed of long-range nerve fibers (myelinated […]

MRI Brain White and Grey Matter

At the level of the cerebral hemisphere, gray matter is mainly distributed in the periphery (cortex) while the white matter is deep. However, there is gray matter in depth of the brain called basal ganglia. In the brainstem, gray matter is usually found in the depth while the white matter is superficial. In the spinal […]

Magnetic resonance imaging (MRI) permits in vivo quantification of brain compartment volume, and has many applications in cognitive, clinical and comparative neuroscience. There dre numerous approaches for obtaining a brain volume estimate from MRI, and the primary focus of this paper is to provide an overview of the methods available to estimate the volume of […]

Magnetic resonance imaging (MRI) of the head is a painless, noninvasive test that produces detailed images of your brain and brain stem. An MRI machine creates the images using a magnetic field and radio waves. This test is also known as a brain MRI or a cranial MRI. You will go to a hospital or […]

Vascular dementia is the second most common type of dementia (after Alzheimer’s disease), affecting around 150,000 people in the UK. The word dementia describes a set of symptoms that can include memory loss and difficulties with thinking, problem-solving or language. In vascular dementia, these symptoms occur when the brain is damaged because of problems with […]

An understanding of cerebral vascular territories is important in understanding stroke and complications from surgery and endovascular procedures. Although one could be excused for thinking that within the brain, such a carefully organised organ, blood supply would be constant, the truth is that a great deal of variety exists. Two main factors contribute to vascular […]

This article corresponds to the classical form of arteriovenous malformation involving the brain parenchyma, which is also referred as a pial arteriovenous malformation, once it is related to the pial vessels 6. These malformations are characterised by a nidus forming the transition between the feeding artery and draining vein. When this transition is made directly […]
