Magnetic resonance neurography (MRN) is the direct imaging of nerves in the body by optimizing selectivity for unique MRI water properties of nerves. It is a modification of magnetic resonance imaging. This technique yields a detailed image of a nerve from the resonance signal that arises from in the nerve itself rather than from surrounding ...
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
Osteoporosis is the weakening of the bones due to progressive decrease in bone density. [13] In older patients, the low bone density of the spine is unable to support the weight of the body. This gives rise to CSM via vertebral compression fractures [ 14 ] promoting further compression of the spinal cord and nerve roots.
Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...
The US National Osteoporosis Foundation recommends pharmacologic treatment for patients with hip or spine fracture thought to be related to osteoporosis, those with BMD 2.5 SD or more below the young normal mean (T-score -2.5 or below), and those with BMD between 1 and 2.5 SD below normal mean whose 10-year risk, using FRAX, for hip fracture is ...
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.

There are two tests that can provide a definite diagnosis of myelomalacia; magnetic resonance imaging (MRI), or myelography. [8] Diffuse hyperintensity on T2-weighted imaging, and hypointensity on T1-weighted imaging of the spinal cord can be an indication of the onset or progression of myelomalacia
[3] [12] Other common steps that are taken may include bone scans to detect possible signs of reduced blood flow; magnetic resonance imaging (MRI) to detect possible edema, or muscle atrophy; Nerve testing can be used to look for pain or sensitivity issues; and X-rays can detect osteoporosis as the result of AMPS.
