  2. Fluid-attenuated inversion recovery - Wikipedia

    en.wikipedia.org/wiki/Fluid-attenuated_inversion...

    It shows enhancement of meninges at the tentorium and in the parietal region, with evidence of dilated ventricles. Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging magnetic resonance imaging sequence with an inversion recovery set to null fluids. For example, it can be used in brain imaging to suppress cerebrospinal ...

    en.wikipedia.org/.../Diagnosis_of_multiple_sclerosis

    Overview. Multiple sclerosis is typically diagnosed based on the presenting signs and symptoms, in combination with supporting medical imaging and laboratory testing. [4] It can be difficult to confirm, especially early on, since the signs and symptoms may be similar to those of other medical problems. [5][6]

    en.wikipedia.org/wiki/Multiple_sclerosis

    0.032% (world) Multiple sclerosis (MS) is an autoimmune disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. [ 3 ] Being a demyelinating disease, MS disrupts the ability of parts of the nervous system to transmit signals, resulting in a range of signs and symptoms, including physical, mental, and ...

  5. Positron emission tomography - Wikipedia

    en.wikipedia.org/wiki/Positron_emission_tomography

    Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging ...

  6. Pathophysiology of multiple sclerosis - Wikipedia

    en.wikipedia.org/wiki/Pathophysiology_of...

    Multiple sclerosis is an inflammatory demyelinating disease of the CNS in which activated immune cells invade the central nervous system and cause inflammation, neurodegeneration, and tissue damage. The underlying cause is currently unknown. Current research in neuropathology, neuroimmunology, neurobiology, and neuroimaging, together with ...

    Main symptoms of multiple sclerosis Symptoms and findings in multiple sclerosis. The signs and symptoms of multiple sclerosis (MS) encompass a wide range of neurological and physical manifestations, including vision problems, muscle weakness, coordination difficulties, and cognitive impairment, varying significantly in severity and progression among individuals.

  8. Lesional demyelinations of the central nervous system

    en.wikipedia.org/wiki/Lesional_demyelinations_of...

    Multiple sclerosis and other demyelinating diseases of the central nervous system (CNS) produce lesions (demyelinated areas in the CNS) and glial scars or scleroses. They present different shapes and histological findings according to the underlying condition that produces them. Demyelinating diseases are traditionally classified in two kinds ...

    en.wikipedia.org/.../Pathology_of_multiple_sclerosis

    MS cord pathology is independent of brain changes, develops at different rates according to disease phenotype, and is associated to medium-term disability accrual. [44] Spinal cord presents grey matter lesions, that can be confirmed post-mortem and by high field MR imaging.
