Mediastinal nodal staging of nonsmall cell lung cancer using integrated ¹⁸F‐FDG PET/CT in a tuberculosis‐endemic country

Abstract

Integrated PET/CT provides high specificity and reasonably high accuracy, but somewhat low sensitivity for mediastinal nodal staging of NSCLCs. The high specificity is achieved at the expense of sensitivity by interpreting calcified nodes or nodes with high attenuation at CT, even with high FDG uptake at PET, as benign in a tuberculosis-endemic region.
