Hello GC_SL2,

A thorax chest CT with contrast cannot detect lymphoma as such. It gives a good picture of lymph nodes, which might raise the possibility of lymphoma and lead to a biopsy or other tests. The radiographer who examines the CT scan won't just be looking for lymph nodes; they will take a good look at all aspects of the scan in case they see anything else unusual.

I had a thorax CT with contrast (after trying the acid reflux tablets which made no difference), and lymphoma is one of the possibilities they are considering. I have since had two biopsies which didn't lead to a diagnosis, and am having another biopsy done by a different technique next week. My symptoms are different to yours though; I'm not having night sweats but I have a 8-month persistent cough.

Good luck with your CT scan.
