    The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures.

  3. Magnetic resonance imaging of the brain - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging...

    The first MR images of a human brain were obtained in 1978 by two groups of researchers at EMI Laboratories led by Ian Robert Young and Hugh Clow. [1] In 1986, Charles L. Dumoulin and Howard R. Hart at General Electric developed MR angiography, [2] and Denis Le Bihan obtained the first images and later patented diffusion MRI. [3]

    HCPCS includes three levels of codes: Level I consists of the American Medical Association's Current Procedural Terminology (CPT) and is numeric.; Level II codes are alphanumeric and primarily include non-physician services such as ambulance services and prosthetic devices, and represent items and supplies and non-physician services, not covered by CPT-4 codes (Level I).

  5. Diffusion-weighted magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Diffusion-weighted...

    Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15]

  6. Computed tomography of the head - Wikipedia

    CT scans may be used to diagnose headaches when neuroimaging is indicated and MRI is not available, or in emergency settings when hemorrhage, stroke, or traumatic brain injury is suspected. [9] MRI (magnetic resonance imaging) provides more sensitivity in the evaluation of the cavernous sinus and the orbital apex. [8]

  7. List of neuroscience databases - Wikipedia

    en.wikipedia.org/wiki/List_of_neuroscience_databases

    A number of online neuroscience databases are available which provide information regarding gene expression, neurons, macroscopic brain structure, and neurological or psychiatric disorders. Some databases contain descriptive and numerical data, some to brain function, others offer access to 'raw' imaging data, such as postmortem brain sections ...

  9. Cerebrospinal fluid flow MRI - Wikipedia

    Due to the development and widespread of PC-MRI, it superseded spin-echo(SE) images, which is the traditional way to choose patients who might benefit from a VPS. And PC-MRI gradually became the most often used sequence to evaluate the CSF flow pattern in patients with NPH in relation to the cardiac cycle. [4] Figure 1.
