  2. Magnetic resonance imaging of the brain - Wikipedia

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

    MRI is sensitive for the detection of brain abscess. [25] A number of different imaging modalities or sequences can be used with imaging the nervous system: T 1-weighted (T1W) images: Cerebrospinal fluid is dark. T 1-weighted images are useful for visualizing normal anatomy.

  3. Central nervous system tumor - Wikipedia

    en.wikipedia.org/wiki/Central_nervous_system_tumor

    Magnetic resonance imaging uses strong magnetic fields, magnetic field gradients, and radio waves to generate images of the structure of the brain. In perfusion MRI a contrast agent , such as gadolinium compounds, may be used to study the structure of the blood vessels around the tumor that provide nutrients and remove waste. [ 13 ]

  4. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.

  5. Atypical teratoid rhabdoid tumor - Wikipedia

    en.wikipedia.org/wiki/Atypical_teratoid_rhabdoid...

    Pediatric brain cancer is the second-leading cause of childhood cancer death, just after leukemia. Recent trends suggest that the rate of overall CNS tumor diagnosis is increasing by about 2.7% per year. As diagnostic techniques using genetic markers improve and are used more often, the proportion of AT/RT diagnoses is expected to increase.

  6. Radiation treatment planning - Wikipedia

    en.wikipedia.org/wiki/Radiation_treatment_planning

    Doctor reviewing a radiation treatment plan. In radiotherapy, radiation treatment planning (RTP) is the process in which a team consisting of radiation oncologists, radiation therapist, medical physicists and medical dosimetrists plan the appropriate external beam radiotherapy or internal brachytherapy treatment technique for a patient with cancer.

  7. Stereotactic radiation therapy - Wikipedia

    en.wikipedia.org/wiki/Stereotactic_radiation_therapy

    Stereotactic radiation therapy is used to treat brain tumors and other brain disorders. It is also being studied in the treatment of other types of cancer , such as lung cancer . What differentiates Stereotactic from conventional radiotherapy is the precision with which it is delivered.

  8. Diffusion-weighted magnetic resonance imaging - Wikipedia

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

    Diffusion-weighted images are very useful to diagnose vascular strokes in the brain. It is also used more and more in the staging of non-small-cell lung cancer , where it is a serious candidate to replace positron emission tomography as the 'gold standard' for this type of disease.

  9. Dysembryoplastic neuroepithelial tumour - Wikipedia

    en.wikipedia.org/wiki/Dysembryoplastic_neuro...

    Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
