The history of magnetic resonance imaging (MRI) includes the work of many researchers who contributed to the discovery of nuclear magnetic resonance (NMR) and described the underlying physics of magnetic resonance imaging, starting early in the twentieth century. One researcher was American physicist Isidor Isaac Rabi who won the Nobel Prize in ...
Raymond Vahan Damadian (Armenian: Ռայմոնտ Վահան Տամատեան) was born in New York City, to an Armenian family.[10] [11] [12] His father Vahan was a photoengraver who had immigrated from what is now Turkey, while his mother Odette (née Yazedjian) was an accountant.
The mean observation time was 3.6 years (range 1–15 years). The researchers concluded: "VS growth occurs within the first 5 years after diagnosis in a limited number of tumors, primarily in tumors with an extrameatal extension. These findings justify primary observation of small tumors."
Craniocervical instability (CCI) is a medical condition characterized by excessive movement of the vertebra at the atlanto-occipital joint and the atlanto-axial joint located between the skull and the top two vertebra, known as C1 and C2. [citation needed] The condition can cause neural injury and compression of nearby structures, including the ...
Average overall survival generally ranges from 8 to 11 months [2] Frequency. ~10–20% of childhood brain tumors [1] Diffuse midline glioma, H3 K27-altered (DMG) is a fatal tumour that arises in midline structures of the brain, most commonly the brainstem, thalamus and spinal cord. When located in the pons it is also known as diffuse intrinsic ...
Otherwise a rigid cervical collar or surgery to immobilize the neck for three months is recommended. [2] If the MRI is abnormal surgery to hold the neck still may be carried out [2] Typically people should avoid further high risk activities for the next six months. [3] The use of corticosteroids is not generally recommended. [2] The condition ...
The field strength of the magnet is measured in teslas – and while the majority of systems operate at 1.5 T, commercial systems are available between 0.2 and 7 T. 3T MRI systems, also called 3 Tesla MRIs, have stronger magnets than 1.5 systems and are considered better for images of organs and soft tissue.

The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
