What does a good MRI of the brain look like?
What is considered a normal brain MRI? Appearance and intensity of brain parenchyma are normal. Ventricular system and cisternal spaces appear normal. No evidence of intracranial space occupying lesion or obvious vascular anomaly is detected.
What is an abnormal brain MRI? In the simplest terms, an abnormal brain MRI means that the scan does not show a healthy brain. The scanned image may show structural damages that may indicate injury but also lesions, inflammation, swelling, and bleeding.
Are white spots on brain MRI normal? White matter lesions are among the most common incidental findings—which means the lesions have no clinical significance—on brain scans of people of any age. They may also reflect a mixture of inflammation, swelling, and damage to the myelin.
