Need context: "hypointense" means "dark" signal on either t1 (more likely) or t2 weighted sequences. These mean different things, and thus more info is needed. You can learn more about MRI scanning (in text and video) here: http://www.Conciergeradiologist.Com/how-does-mri-work.Html. Be sure to check out related pages on the site to learn more about all things mri, especially as it relates to your case.

MRI Description: Structures seen on MRI can be described as being hypointense. They mean a hypointense signal, where an area of darkness in the image is hypointense, and a bright area is hyperintense, with the middle as isointense. The meaning varies depending on the sequences or technique used to scan, so the description is relative. For example: water is hypointense in certain images and hyper in others.
