What Does The Following Test Report Indicate?
Question: Can you interpret this for me? I dont meet with my oncologist until May 19. I was recently doagnosed with mediastinal seminoma. Conpleted 3xBEP chemo January 30.
Brief Answer:
There is activity in the chest area but required detailed analysis
Detailed Answer:
Dear Sir,
Thanks for writing in.
The picture on the screen is showing mild activity of the radio tracer in the thorax and mediastinum. It is important to do a detailed analysis of the investigation which you have taken and it is difficult to come to a conclusion based on the screen shot image you have given.
A PET scan tells the amount of radio tracer activity and the conclusions are made by calculating the SUV values in different parts of body including the areas where you had enlarged lymph nodes.
A PET image is usually superimposed over a CT scan picture and then a detailed analysis is done.
From your image once can say that there is some activity in the previously involved areas in the thorax but the exact value of uptake and the time duration from the injection cannot be commented upon just by looking at the picture.

Thank you. If it were cancer wpupd it not be pitch black in colour, like that shown in yhr bladder?
Brief Answer:
Less black means lesser activity but all pictures to be studied
Detailed Answer:
Hi Sir,
Thanks for writing back with an update.
I understand your concern that the areas in the chest are not as black which is visualised in the kidneys and bladder.
The activity is to be measured at specific time intervals and then the SUV of the tracer is measured using the density of signals in that area.
I cannot comment about the exact uptake from the picture you have given because we do not know the time duration of acquisition.
So far you might be right in saying that the absence of dark black could mean that the uptake is not as much but then this can be the result of a treatment changes.
