Areas of new, active inflammation in the brain become white on T1 scans with contrast. The spots (called lesions) on the scan are areas of active inflammation.


The presence of these anomalies, called white matter hyperintensities, characterizes elderly subjects as well as ischemic stroke patients, regardless of their age.

Relative sparing of the periventricular white matter will be seen (, 42). Figure 14a.

15,43,44 In healthy people, white matter lesions were associated with cognitive dysfunction and increased risk for dementia, stroke, and Ischemic lesions could lead to secondary degeneration in remote regions of the brain. However, the spatial distribution of secondary degeneration along with its role in functional deficits is not well understood. In this study, we explored the spatial and connectivity properties of white matter (WM) secondary degeneration in a focal unilateral sensorimotor cortical ischemia rat model, using The 2010 revised McDonald criteria refer to the geographic and chronologic distribution of MS: dissemination in space requires at least one white matter hyperintensity (WMH) in at least two typical locations such as periventricular, juxtacortical, infratentorial, and spinal cord; dissemination in time requires both contrast-enhancing and nonenhancing lesions in a single MR imaging examination significant component of the ischemic lesion burden in stroke patients [18]. WMLs do not have a specific etiology or pathology, but the lesions commonly seen in asymptomatic elderly in-dividuals seem to be largely ischemic in origin [19].

The Fazekas scale is used to simply quantify the amount of white matter T2 hyperintense lesions usually attributed to chronic small vessel ischemia, although clearly not all such lesions are due to this. The result is the formation of small ischemic lesions, primarily involving the deep cerebral and periventricular white matter as well as the basal ganglia (Fig. 7.4). White matter disease, or leukoaraiosis, involves the degeneration of white matter in the brain. White matter is tissue that includes nerve fibers (axons), which connect nerve cells. A fatty tissue Axial T2WI MR in a middle-aged patient with unexplained mental decline and normal neurologic examination shows multifocal white matter hyperintensities (WMHs).
