MRI scans showing hyperintensities. A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss.
The term "leukoaraiosis" was coined in 1986 [6] [7] by Hachinski, Potter, and Merskey as a descriptive term for rarefaction ("araiosis") of the white matter, showing up as decreased density on CT and increased signal intensity on T2/FLAIR sequences (white matter hyperintensities) performed as part of MRI brain scans.
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.
Face of the giant panda sign; Axial T2-weighted MRI of the brain at the level of the midbrain showing the characteristic ‘face of the giant panda’ sign, with normal red nuclei and substantia nigra (pars reticulata) against a background of hyperintensity in the tegmentum, as well as hypointensity of the superior colliculi
I acknowledge that getting this scan is a major expense, and a privilege, as their scan prices start at $1,000. I should also note that not all experts think a full-body MRI scan is totally necessary.
Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging sequence with an inversion recovery set to null fluids. 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.

An MRI instead of a surgical procedure helped speed up the wait between diagnosis and treatment, UK research has found MRI scan could fast-track patients for bladder cancer treatment, study finds ...
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
