Can MS lesions be punctate?
Can MS lesions be punctate?
The lesions can be punctate or patchy and are more common in the supratentorial white matter where they can be present at any site, though most often are subcortical rather than periventricular.
What do brain lesions look like on a 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 CAT scan and a CT scan?
A CT scan is a form of X-raying that involves a large X-ray machine. CT scans are sometimes called CAT scans. A CT scan is typically used for: During a CT scan, you’ll be asked to lie down on a table.
What are bright spots on a MS MRI?
MS lesions appear as bright spots in a T2-weighted MRI scan. More T2-hyperintense lesions identified by a T2-weighted MRIs may mean higher levels of disability.
What causes the spots on a brain MRI?
Spots on a brain MRI are called leukoaraiosis, and they are caused by the changes in water content and fluid movement that occur in brain tissue when the brain cells are inflamed or damaged.
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.
Can a breast lesion be detected with a CT scan?
Breast lesions may be better imaged with multidetector CT compared with mammography if the breasts are dense (, 2) or if the lesion is located near the chest wall, and while the breasts are not the primary focus of most scans of the chest, abnormal findings are not uncommon (, 3,, 4 ).
What does it mean if you have spots on your MRI?
Claudia Chaves, MD, is board-certified in cerebrovascular disease and neurology with a subspecialty certification in vascular neurology. You may have been told that you have “spots” on your brain magnetic resonance image (MRI). Certainly, spots may be a cause for concern, and they may explain the symptoms for which you had your brain MRI.
