The bone on this T1 weighted MRI appears darker than usual. With appropriate treatment the water signal will decrease and the lipd signal will increase. We have shown that these disease processes are best shown with fat suppression and with contrast enhancement. Brain diffusion Perfusion imaging helps define areas of over- or under perfusion. Determination of blood perfusion is critical to determine salvageable brain tissue in patient with strokes.
Perfusion requires an intravenous injection of contrast material.
This often delays perfusion measurements. This is a study of a tumor implanted into a rat's thigh. We are using a new experimental MRI sequence that does not require a intravenous bolus injection.
