Specializes in Diagnostic Radiology

Not often: Retro peritoneal attenuation is and unusual term on ct. CT is usually very good at detecting enlarged lymph nodes of lymphoma . And understand that not all lymphomas will be best seen with PET. Also not every positive PET CT is cancer. There are other disease entities that are positve on PET. Talk honestly with the doctor to wxplain the results
