What does a white spot on MRI mean?

What Are White Spots? Spots on a brain MRI are caused by changes in water content and fluid movement that occur in brain tissue when the brain cells are inflamed or damaged. These lesions are more easily seen on T2 weighted images, a term that describes the frequency (speed) of the radio impulses used during your scan.

Do white spots on MRI mean MS?

White matter lesions observed on brain MRI are usually characteristic and occur in specific areas including the corpus callosum and pons. “However, in many cases, the white matter lesions as isolated observations are nonspecific” and could be due to MS or another cause, explained Drs Lange and Melisaratos.

What are the white spots on my spine MRI?

These have a variety of names including high signal change, white matter change and small vessel disease. Sometimes they are even called ‘Unidentified Bright Objects or UBOs’. These white dots start to appear with increasing frequency as you age in healthy people. Roughly, its OK to have one dot per decade.

What causes white matter lesions on MRI?

Evaluation of patients presenting with white matter lesions (WMLs) depends on the age of the patient, clinical scenario, and pattern of white matter lesions on MRI. WMLs on MRI are common manifestations of cerebral small vessel disease and are associated with vascular risk factors.
