Does white matter mean dementia?

WMD is thus defined as a dementia syndrome resulting from diffuse or multifocal cerebral white matter damage (Filley et al., 1988; Filley, 1998; Schmahmann et al., 2008).

What do white spots on a brain CT scan mean?

Increased numbers and size of the intense-white spots seen on the mostly gray images of the brain have long been linked to memory loss and emotional problems, especially as people age.

What shows up as white on a CT scan?

Bone absorbs the most X-rays, so the skull appears white on the image. Water (in the cerebral ventricles or fluid-filled cavities in the middle of the brain) absorbs little, and appears black. Most ischemic strokes are less dense (darker) than normal brain, whereas blood in hemorrhage is denser and looks white on CT.

Can you see blood clot on CT scan?

CT scans detect and diagnose blood clots by providing detailed, accurate imagery of the body’s blood vessels and their obstructions. Doctors generally use two CT scan techniques for blood clot detection and diagnosis — CT venography and CT pulmonary angiography.

Do brain lesions show on CT scan?

A brain lesion is an abnormality seen on a brain-imaging test, such as magnetic resonance imaging (MRI) or computerized tomography (CT). On CT or MRI scans, brain lesions appear as dark or light spots that don’t look like normal brain tissue.

What is the difference between a lesion and a nodule?

A pulmonary nodule can be benign or cancerous. Lesions larger than 3 cm are considered masses and are treated as cancerous until proven otherwise. Lung nodules are quite common and are found on one in 500 chest X-rays and one in 100 CT scans of the chest.

What are the causes of bone lesions?

Bone lesions are areas of bone that are changed or damaged. Causes of bone lesions include infections, fractures, or tumors. When cells within the bone start to divide uncontrollably, they are sometimes called bone tumors. Most bone lesions are benign, meaning they are not cancerous.
