Periventricular low density change

Web1. máj 2001 · Changes in subcortical white matter and deep gray matter nuclei are often noted in the brains of elderly people. Typically, these changes appear as foci of increased signal (hyperintensity) on T 2 -weighted magnetic resonance (MR) imaging or as areas of low density (attenuation) on computed tomography (CT) ( Figure 1A, Figure 1B, Figure 1C ). WebThese changes have been described using numerous terms including white matter abnormalities, cerebral white matter changes, unidentified bright objects (UBOs), or leukoaraiosis—used to refer to all white matter changes visible on neuroimaging studies. In 1894, Binswanger described the case of a male with syphilis who suffered from a ...

WebBy the late 1990s the use of fast spin echo signal generation significantly reduced imaging times and T2-FLAIR became a standard protocol for routine imaging. Today, the venerable old spin-density sequences (long TR/Short TE spin echo) have been nearly completely replaced by T2-FLAIR imaging, at least in neuroimaging.
