A member asked:
What's the difference between sclerotic and hypermetabolic lesions?
A doctor has provided 1 answer
Please see answer: Sclerotic means "hardening" or lack of pliability. An example is arteriosclerosis in which the arteries become hardened due to calcification and scarring(fibrosis). A hypermetabolic lesion is a lesion seen on a PET scan with increased metabolism, such as cancer(which takes up more glucose than normal tissue). A form of glucose is labeled with a radioactive "tracer" and this tracer is seen on PET.
