Ask a Doctor and Get an Answer to Your Medical Question ASAP
Hi there. Thank you for your question. I will be helping you out with your queries
What they are trying to say in this PET scan report is that the lesion that they previously saw on the CT scan is not a metastasis i.e. the 15 mm lesion that you previously described is not a liver metastasis (most likely). But they see another lesion in the liver (which is not seen on the CT scan, but seen on the PET scan) that is 16 mm in size and is also in the periphery of the liver and is most likely a liver metastasis.
So you do have a liver metastasis according to the PET scan report which is in fact different from the lesion seen on the CT scan initially.
For the lymph nodes they are saying that they are not sure if this is due to metastasis or something else but they do say that there is some uptake in the lymph nodes as well which means there may be a suspicion of metastasis there as well but not sure.
Let me know if you have more questions.
Rate me when you are done.
Hi thx alot . I was very confussed by the report . So it's nit the same lesion as pet the previous ct report ? So what was that lesion on the ct report ? And whaT can be done re the nodes to find if they have mets in them as we want to start treatment ASAP ?
The only way to know for sure is biopsy.
For the met they say surgery or microwave but my worry is the nodes too . Which nodes are they in the body ?
The lesion previously reported on the CT scan is most likely not a metastasis, we do not know what it is unless a biopsy is done.
The nodes that they are talking about are the nodes around the major blood vessels i.e. the aorta and the inferior vena cava
So there are 2 diff lesions they are talking about ?
two different lesions
One of them is a metastasis and the other one is most likely not a mets
That's very strange as the lesion on ct was thought to be a met but them Infact it's not and Znother one found instead.
So what could the other one be ?
We do not know but it does not look like a met
What does it mean by not seen on co- registeted ct ?
Actually when they read the report of the PET scan, they do a CT scan simultaneously as well. So they compare the lesions on the PET scan and the CT scan to see if we can see something on the PET scan and the CT scan at the exact same spot.
Should they not do a biopsy of the actual met invs
Not seen on the co-registered CT means that they saw something on the PET scan on the liver at a spot where there was nothing found on the CT scan on the same spot.
Shud they not do a biopsy as this may not b met too?
Well, that is up to them, a biopsy, although difficult, could be possible.
You should discuss this with your doctor
I mean the biopsy thing.
But a PET scan is very accurate in detecting mets
So I am pretty sure that the lesion that was discovered on the PET is a met in the liver
But as there was uptake that is a met right ? How cum
How cum this was not seen on ct Scan which was 1 6 mm and the 15 mm lesion was seen ?
In a PET scan they use radiolabelled glucose. Cancer cells take up far more glucose than other parts of the body. So if there is a mets it will take up this radiolabelled glucose far more than other parts of the body and it will glow.
This is exactly why a PET scan is done. CT quite often misses things which PET scan picks up.
Y coujd this 16 mm not have shown on the ct?
Yes it is possible for CT to miss things
So what can we do about this nodes ? I'm worried they may well have mets if there was uptake right.
I can't explain why CT missed it but the fact is that it was missed
Good job they did pet as other wise this non met lesion may have been treated and we may not have known nothing about the 16 mm met right?
So even though no other mets seen at present. , could they still b too tiny too be seen on pet in other parts? I'm just worried that it travelling ( the cells ) through the body. ?
I understand your concerns.
The next best thing to do is to wait for your oncologist opinion and the surgeon's opinion and go along with that. Just let the experts do the thinking.
