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.
Ultra-detailed MRI scans reveal brain damage in severe COVID-19 The researchers used a relatively new scanning technology called ultra-high field (7T) quantitative susceptibility mapping.
The presence of incidental MRI findings in the CNS white matter: Ovoid and well-circumscribed homogeneous foci, with or without involvement of the corpus callosum; T2 hyperintensities larger than 3 mm in diameter, which fulfill at least 3 of the 4 Barkhof MRI criteria [7] for DIS; The CNS abnormalities are not consistent with a vascular condition
The increasing use of MRI, often during diagnostic work-up for back or lower extremity pain, has led to a significant increase in the number of incidental findings that are most often clinically inconsequential. The most common include: [22] vertebral hemangioma; fibrolipoma (a lipoma with fibrous areas) Tarlov cyst
In search of a Valentine, I asked men throughout the country to apply for a once-in-a-lifetime date in New York City. Casey Johnson and I had one virtual date and then we met Tuesday, ...
