Guys I was doing some questions in FA questions and answers and I found that Progressive Multifocal Leukoencephalopathy (PML) typically presents as multiple non-enhancing T2-hyper-intense lesions????? What does that mean????? I don't get the T2?????
Maybe I am to tired know and my brain is not working good.
Someone???????
T2 and T1 are two different modes in MRI.
One is better for intracellular edema and the other for hemorrhages or something like that.....I learnt it in radiology internship a yr ago, keep forgetting which is which.
Don't feel stupid my friend, every day we learn something new. There's a lot of stuff we have to learn for this exam so every post in this forum helps.
fat-containing tissues are dark. The reverse is true for T1-weighted images. Damaged tissue tends to develop edema, which makes a T2-weighted sequence sensitive for pathology, and generally able to distinguish pathologic tissue from normal tissue
