mid lung zone

“The nodule in the right mid lung zone no longer exhibits increased metabolic activity. That has decreased in size currently measuring approximately 11 x 4 mm compared to 16 x 10 mm previously.”

“right mid lung zone” is not an accurate localization on a PET-CT. It is impossible to visualize the lesion from this description.
I have to make up an anatomic location for the purpose of rewriting this sentence:
”11 x 4 mm posterolateral right upper lobe nodule is no longer hypermetabolic, and decreased from the previous 16 x 10 mm.
