Liver hemangioma, the most common benign liver lesion. time constant An MRI term for the time constant for the loss of phase coherence among spins oriented at an angle to the static magnetic field, which is due to a combination of magnetic field inhomogeneities and spin-spin relaxation, resulting in a rapid loss of transverse magnetisation and the MRI signal. Debette and Markus (2010) performed a meta-analysis of 22 studies that examined the association of white matter hyperintensities with stroke, cognitive decline, dementia, and death. This is most likely during menstruation, pregnancy, and the postpartum period. 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.
