MRI, or magnetic resonance imaging, is the scanning procedure used in medicine for examining the insides of the human body. The MRI procedure may require a special contrast agent. The contrast agent is required for those images that need finer resolution. In some cases both MRI with contrast and MRI without contrast are performed to […]
Brain tumor is an abnormal and often uncontrolled growth of cells, and takes up space within the cranial cavity (skull). It can compress, shift and/or invade and damage healthy brain tissue and nerves and usually interferes with normal brain function. Tumors can be benign (non-cancerous) or malignant (cancerous), can occur in different parts of the […]
The WHO classification of CNS tumours is the most widely accepted system for classifying CNS tumours and was based on the histological characteristics of the tumour. Although the most recent version of the ‘blue book’ is the 4th edition from 2007, an update has been released in 2016 3, which should be considered a replacement […]
Brain tumors are the most common solid tumors in children. Approximately 4,000 children and adolescents in the U.S. are diagnosed with primary brain tumors each year. Primary brain tumors start in the brain and generally do not spread outside the brain tissue. Most central nervous system cancers are brain tumors. Brain tumors, either malignant or […]
Tuberculosis of the central nervous system can result from either haematogenous spread from distant systemic infection (e.g. pulmonary tuberculosis) or direct extension from local infection (e.g. tuberculous otomastoiditis). Intracranial manifestations of tuberculosis are protean and can affect all compartments and are discussed individually in separate articles.

MRI can detect a variety of conditions of the brain such as cysts, tumors, bleeding, swelling, developmental and structural abnormalities, infections, inflammatory conditions, or problems with the blood vessels. It can determine if a shunt is working and detect damage to the brain caused by an injury or a stroke. MRI of the brain can […]
This article addresses the problem of the tissue type parameter estimation in brain MRI in the presence of partial volume effects. Automatic MRI brain tissue classification is hampered by partial volume effects that are caused by the finite resolution of the acquisition process. Due to this effect intensity distributions in brain MRI cannot be well […]
