How much?: You had both a pet scan and a ct scan as they are used together. Sometime a small amount of fluid on the lung that is not "hot" on pet scan can be normal. Depending on how much fluid and whether or not there tumors notes anywhere else and whether or not the fluid is metabolically active, your oncologist may decide to sample the fluid or just watch it. Need to discuss your scan with oncologist.
