What does it mean "may be very slightly more conspicous" for a white matter lesion?

What does it mean "may be very slightly more conspicous" for a white matter lesion?

Generic response: If a pre-existing white matter lesion has become larger or more prominent, this could be a sign of disease activity in form of inflammation, but could also be a feature of a stronger magnet or a more precise MRI device. You need to talk to your doctor regarding correlation with your symptoms. ...Read more

White Matter (Definition)

White matter is one of the two components of the central nervous system and consists of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers. White matter tissue of the freshly cut brain appears pinkish white to the naked eye because myelin is composed largely of lipid ...Read more

I had to pull an all nighter last night & got zero sleep. Will the sleep deprivation cause abnormalities on my MRI I had today?White matter lesion?

I had to pull an all nighter last night & got zero sleep.  Will  the sleep deprivation  cause abnormalities on my MRI I had today?White matter lesion?

One night is prob OK: While long-term sleep deprivation can be associated with structural brain changes (C. Liu et al., NeuroReport 2014 25(5):320-3), a single night is unlikely to alter the findings of a structural MRI study. … but it IS likely to alter measures of brain function. ...Read more

What does a hypodense white matter lesion on CT scan mean?

White matter lesions: Lesions in the brain are not good. Hypodense lesions are seen which lead to further studies to evaluate the lesions for infection or malignancy. Discuss any findings with your neurologist (ms, sarcoid) or neurosurgeon. ...Read more

What is the difference between a non active white matter brain lesion and an active one?

What is the difference between a non active white matter brain lesion and an active one?

Contrast enhancement: Active white matter lesions tend to contrast enhance on MRI. Inactive lesions do not. You can see contrast enhancement on a contrasted CT scan but you cant see a lot of the MS plaques that are there without MRI sequences designed to identify MS plaques (FLAIR sequences and to a lesser extent T2 weighted images will reveal MS lesions that would escape detection otherwise. ...Read more

Mri states a few scattered foci of adnormal t2/flare hypersensitivity (periventricular white matter) largest lesion 5mm. Possible ms? More testing?

Mri states a few scattered foci  of adnormal t2/flare hypersensitivity (periventricular white matter) largest lesion 5mm.  Possible ms? More testing?

Complex: The MRI abnormalities might be nonspecific, and caused by other processes. MS is a clinical diagnosis, confirmed by films, and you need your doctor to explain why you seem to have lesions on your films. Urge you get clearcut diagnosis, and treat the problems plaguing you. ...Read more

MRI done showed brain lesion... If it were white matter disease would they have known by this MRI?

MRI done showed brain lesion... If it were white matter disease would they have known by this MRI?

Likely: MRI is the study of choice for evaluating the soft tissues of the brain. Sometimes IV contrast is used to also evaluate the blood vessels of the brain. ...Read more
