Imaging Spectrum in Pulmonary Tuberculosis

Abstract

AbstractPulmonary tuberculosis is one of the most common pulmonary infections prevalent in our country. Although definitive diagnosis is microbiological, characteristic imaging features help in establishing a certain diagnosis in most of the cases. While chest radiography remains the primary screening tool, computed tomography helps in clinching the diagnosis with a spectrum of findings described on cross-sectional imaging. The radiologist must be familiar with the features denoting potential complications and differential diagnosis to aid better treatment planning and case prognostication. This article describes in detail the imaging features of pulmonary tuberculosis, active disease, disease sequelae, and complications.
