  2. Cerebrospinal fluid flow MRI - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_Fluid_Flow_MRI

    Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [1] CSF Fluid Flow MRI detects back and forth flow of Cerebrospinal fluid that corresponds to vascular pulsations from mostly the cardiac cycle of the choroid plexus. Bulk transport of CSF, characterized by CSF circulation through the Central ...

  3. CSF tap test - Wikipedia

    en.wikipedia.org/wiki/CSF_tap_test

    The CSF tap test, sometimes lumbar tap test or Miller Fisher Test, is a medical test that is used to decide whether shunting of cerebrospinal fluid (CSF) would be helpful in a patient with suspected normal pressure hydrocephalus (NPH).

  4. Suboccipital puncture - Wikipedia

    en.wikipedia.org/wiki/Suboccipital_puncture

    A suboccipital puncture or cisternal puncture is a diagnostic procedure that can be performed in order to collect a sample of cerebrospinal fluid (CSF) for biochemical, microbiological, and cytological analysis, or rarely to relieve increased intracranial pressure.

  5. Pandy's test - Wikipedia

    en.wikipedia.org/wiki/Pandy's_test

    Proteins in the cerebrospinal fluid, normally albumin and globulin are present in the ratio of 8 to 1. Increases in protein levels are of diagnostic value in neurological diseases. The normal CSF is clear and transparent fluid. The Pandy's reaction makes it translucent or opaque.

  6. Cerebrospinal fluid diversion - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid_diversion

    Cerebrospinal fluid diversion is a procedure that is used to drain fluid from the brain and spinal cord. A shunt is placed in a ventricle of the brain and threaded under the skin to another part of the body, usually the abdomen. It is used to treat hydrocephalus and idiopathic intracranial hypertension.

  7. Intracranial pressure - Wikipedia

    en.wikipedia.org/wiki/Intracranial_pressure

    Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]

  8. Lymphocytic pleocytosis - Wikipedia

    en.wikipedia.org/wiki/Lymphocytic_pleocytosis

    Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system , and is encountered in a number of neurological diseases , such as pseudomigraine, Susac's syndrome, and encephalitis.

  9. Aqueductal stenosis - Wikipedia

    en.wikipedia.org/wiki/Aqueductal_stenosis

    Phase contrast-MRI is an imaging method that is more sensitive than MRI for analysis of the pulsatile CSF flow in the ventricular system. This method takes multiple images of the ventricles within one cardiac cycle to measure the flow of CSF running past the area of acquisition. If no flow is seen, this is a reliable diagnosis of aqueductal ...
