The use of standardized uptake values (SUVs) is to differentiate;
1) Non canerous
Interval development of extensive confluent infiltrative process region within the right perihilar region with extension into the adjacent right mid lung with associated air bronchograms and ill-defined FDG uptake with maximal SUVs ranging up to 7.6.
This is due to infection.
No focal more intense hypermetabolic lesions are identified within the lung parenchyma.
There is no residual cancer left.
Small 1.3 cm hypermetabolic focus is noted within the right subcarinal region adjacent to surgical clip with a maximal SUV of 8.6.
This shows the residual inflammation at the surgical site.
No other suspicious hypermetabolic lesions are noted within the chest.
There is no other area which has high uptake of glucose in PET scan.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
