Thread: How long after radiation before it's time for a PET-CT?

  1. #1

    How long after radiation before it's time for a PET-CT?

    I seem to remember the doc saying 6 weeks. My wife said she heard 4 months. What's the norm?

    It was 6 weeks after WBR and 6 weeks after SRS. Never knew how long 6 weeks could be.
    As long as there is Life, there is Hope.

    Husband (44) with LC, mets to brain, lymph nodes and bones. Received Carbo/Taxol, currently in a clinical trail. Had WBR, stereotactic radiation to brain

    About 6 weeks for chest rads too, otherwise the scans can pick up irritation from the rads causing a false positive reading.

    I vote 6 weeks, 4 months is more the interval between regular CT scans.

    I agree with everyone ease. Dano did clarify one additional thing... 4 months between scans. I have not had lung cancer and my brain cancer is followed be MRI's. After my radiation, I had to wait 6 weeks before my first MRI. Now the interval is 8-9 months but it started at 2 months, then 4.

    I was just reading my husband's story again. How quick we forget all these unpleasant dates! He ended up in the hospital before his chemo and radiation were done. I am sure they did CTScans. They knew the tumor was shrinking. His last radiation was about a week before a scheduled PetScan. Pet was on April 7th.

    I think we all sort of discussed that on this forum one time. I don't think my husband's was the norm but there was some reason for it. He ended up with surgery on May 16th. I do remember that I was told about the waiting or they pick things up wrong ont he Pet Scan..

    Never hurts to ask the doctors or nurses. We are entitled to know. Best of luck to you.

    I'm looking forward to those dates stretching my self Jim, I just had a MRI this morning, getting my head checked! I think something is still rattling around up there. But it's been at least 5 months sense the last one and I likely wont hear about this one until the 18th of this month on my regular visit, I'll hear sooner if there is trouble but we doubt it.
    Some say there is nothing up there to begin with.... they may be right.....I'll have to think about it.......mom always said life was like a box of chocolates.....You never know.....

    Hey ---

    I'm happy to hear that ANYONE is at the point of stretching the time between tests! Good luck Dano -- I'll be praying for gray matter only!

    As far as scans and timing, it is up to each oncologist and how they operate. CT and PET scans are another thing and often dependent on what the insurance will cover. My husband had both CT/PET scans every three months like clockwork. This was how our oncologist handled all patients. He also ALWAYS reviewed the films himself on top of getting the reports. Everyone will experience slightly different time frames for the scans.

    Good luck to all!

    how long

    Bens' last chemo was 8/25/08, and his last radiation was 11/4/08. The oncologist appt is 12/4/08, and then I expect a CT scan of his head and lungs will be ordered. That's the time frames we have.
    I , personally, hate the waiting, and am trying to learn how to have what used to be a life back. Very odd how I have had to re- learn my life- kind of like that commercial we all laugh at : how to relearn things without cigarets, like driving.-- I know how that woman feels! I quit when he had his 4th chemo.
    so, I am learning how to wait, and how to do the things that Ienjoy - with him
    I ramble, I know...
    Take care, and God Bless Us,
    Every One.

    Gillette,

    Ramble away! That's what we are all here for and I certainly seem to have a corner on the rambling market myself. LOL

    You are trying to adjust to what we call the "new normal" of having cancer as a main feature of your life. It's a struggle, to be sure. Some days the stress, upset, and anger is so bad that you want to scream... or cry. That's all okay!

    Congratulations to you on your HUGE accomplishment of quitting smoking. Wow! Even though my hubby hadn't smoked for over 23 years prior to diagnosis, I still continued to smoke (always outside) and haven't kicked the habit yet. Food and cigs -- my comfort zone. I can rationalize my smoking like you wouldn't believe too. Pretty pathetic. It's GREAT that you took the bull by the horns during such a stressful time. I REALLY admire your strength.

    No matter how small the world seems to get while fighting the beastie, there are still those things that you can do together as a couple. Take the opportunities when they present themselves and go for it. You'll find that even very small and simple things can become very meaningful for the two of you. I'm sure you've noticed a deepening of your relationship too. It's amazing that little blessings can be found even in the face of a journey like this.

    Hugs,
    PBJ
