  2. Cerebrospinal fluid flow MRI - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_Fluid_Flow_MRI

    The partial volume effect occurs when a voxel includes a boundary of static and moving materials, this leads to an overestimate of phase which results in inaccurate velocities at material boundaries. These quantitative and qualitative CSF flow images can be acquired in about 8-10 additional minutes than a regular MRI. [4]

  3. Cerebrospinal fluid leak - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid_leak

    Contrast-enhanced brain MRI with sagittal reformats can assess for the following: [6] [8] Subdural fluid collections; Enhancement of the meninges; Engorgement of venous structures; Pituitary swelling; Sagging of the brain; For suspected spinal CSF leaks, spine imaging can be used to guide treatment. [8]

  4. Fluid-attenuated inversion recovery - Wikipedia

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

    For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions, such as multiple sclerosis (MS) plaques. [1] It was invented by Graeme Bydder, Joseph Hajnal, and Ian Young in the early 1990s. [2]

  5. Cisternography - Wikipedia

    en.wikipedia.org/wiki/Cisternography

    Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...

  6. Magnetic resonance imaging of the brain - Wikipedia

    T 1-weighted images are useful for visualizing normal anatomy. T 2-weighted (T2W) images: CSF is light, but fat (and thus white matter) is darker than with T 1. T 2-weighted images are useful for visualizing pathology. [26] Diffusion-weighted images (DWI): DWI uses the diffusion of water molecules to generate contrast in MR images.

  7. Tarlov cyst - Wikipedia

    en.wikipedia.org/wiki/Tarlov_cyst

    MRI provides better resolution of tissue density, absence of bone interference, multiplanar capabilities, and is noninvasive. Plain films may show bony erosion of the spinal canal or of the sacral foramina. [citation needed] On MRI pictures, the signal is the same as the CSF one. If MRI made with a contrast medium: [citation needed]

  8. Subdural hygroma - Wikipedia

    en.wikipedia.org/wiki/Subdural_hygroma

    Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]

  9. Cerebrospinal fluid rhinorrhoea - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid_rhino...

    Traumatic CSF rhinorrhoea is the most common type of CSF rhinorrhoea. [1] It may be due to severe head injury, or from complications from neurosurgery. [1] Spontaneous CSF rhinorrhoea is the most common acquired defect in the skull base bones (anterior cranial fossa) causing spontaneous nasal liquorrhea.
