Subject:      Is there a way to define an anulus?
Comments: To: [log in to unmask]

Wayne and others:

Is there a way to define an annulus? We are studying the ability of
contrast agents to detect changes in the contrast enhancement of tumors
(DEMRI or DCE-MRI) and because many solid tumors develop a necrotic core,
it there any way to define the ring (annulus) so as to generate a kinetic
plot of that ring from a temporal stack of MRI images?

Any suggestions would be appreciated. Thank you.
