Radio Oncologist is suggesting a combo pet/ct scan with a contrast. But I don't know what the contrast is. Has anyone had this scan? He doesn't think a repeat bone and ct scan alone would reveal anything. I agree on the bone scan since the psa still isn't beyond 10-20. Any thoughts on pet scan??? Thanks guys

Hope this anwers yoru question:
A PET scan requires a small amount of radioactive material (tracer). This tracer is given through a vein (IV), usually on the inside of your elbow. It travels through your blood and collects in organs and tissues. The tracer helps the radiologist see certain areas or diseases more clearly.

BUD Added - to include Bone...

You will need to wait nearby as the tracer is absorbed by your body. This usually takes about 1 hour.

Then, you will lie on a narrow table, which slides into a large tunnel-shaped scanner. The PET scanner detects signals from the tracer. A computer changes the results into 3-D pictures. The images are displayed on a monitor for your doctor to read.

You must lie still during test. Too much movement can blur images and cause errors.

How long the test takes depends on what part of the body is being scanned.

I've had two done in the last 10 months or so - simple.

If I were in your shoes, I would be looking into a C- 11 Choline PET/CT scan:

Has anyone here on the forum done this?

The contrast usually contains iodine, which is usually expected to be well tolerated (since we have iodine in our systems all the time anyway). Occasionally people have a reaction to the contrast, usually the only way to tell unfortunately is to find out the first time you have a scan.

If you have had a reaction to any medications containing iodine, you should let them know.

I just recently had a F18 Sodium PET/CT Bone Scan.  It is my understanding that this type of test is much more sensitive.

I agree with UpstateGuy, C11-Cholin will show areas of activity whereever they may be, lymph nodes, bone, prostate. From my understanding the F18 Sodium scan, although very sensitive, shows only the affected bones. All the best.

PaxNova,

My husband had the F-18 Pet Scan and FDG.
The soduim floride F-18 Pet scan shows BONE mets. and the FDG shows SOFT tissue mets.

It did show an isolated met to his T-11 spine.

Read stats below!

Good luck

There is a new Phase II trial with Carbon-11-Acetate PET/CT imaging for Prostate Cancer:in Phoenix under Dr. Almeida for which he is now recruiting (see latest PCRI Weekly).

I do not know if it is better than the C 11 Choline PET/CT scan. Has anyone tried this?
