Wondering how these are typically used. If I'm remembering correctly, my husband's last pet scan was in March - before surgery and only showed the rectal tumor. Tumor was removed in April. His CEA has been good since surgery. Though it's been going up slightly, it's been under 1.0 since surgery (.5 in June, .6 in July and .7 in August) Had a CT scan on Saturday and we find out the results this afternoon. I read somewhere - think it was on colonclub, that CT is not the best for picking up lymph nodes. He's stage 4 because of distant nodes (para-aortic) at diagnosis - those were removed in Sept and nothing else has lit up since, but he's been off chemo since March.
So, when is MRI typically used? Tans - does your wife have yearly MRIs? I know she had para-aortic nodes also - is MRI better at picking up nodes?
Onc said she didn't think she could get another Pet Scan approved at this point, unless something showed up on the CT. Just wondering if monthly CEA checks and 6 month CTs are the standard?
