Evaluation of high resolution computed tomography (HRCT) in diagnosis of pulmonary tuberculosis and deciding activity of the disease
Journal Title: Medpulse International Journal of Radiology - Year 2018, Vol 6, Issue 2
Abstract
Background: HRCT is a useful adjunct to Chest radiography for diagnosing the tuberculosis and is more sensitive than conventional radiography in detection and characterization of parenchymal disease and lymphadenopathy in the mediastinum. The high sensitivity of HRCT provides an edge and may allow prompt diagnosis before the culture reports arrive. Aim: To evaluate the role of high resolution computed tomography in diagnosis of pulmonary tuberculosis and deciding activity of the disease. Material and Methods: A total of 200 patients suspected with pulmonary tuberculosis, smear negative with strong suspicion of tuberculosis, clinical suspicion of tuberculosis and not confirmed by other modality such as conventional radiography, smear positive patients during their follow up were studied. Two sputum samples were collected and sent for Z-N stain. After clinical workup, examining radiographs, patients were subjected to HRCT imaging. Results: The majority of patients were diagnosed as pulmonary tuberculosis (79%) and 42 (21%) patients were diagnosed as non-TB. The patients according to non-TB diagnosis were diagnosed as interstitial lung disease (76.17%) followed by malignancy (16.67%) and 3 (7.14%) patients were diagnosed as fungal disease.The common finding seen on HRCT were nodules both centrilobular (56%). Other important findings included lobular consolidation (53%) and cavities (45.5%). Conclusion: HRCT is a powerful and reliable investigation in the diagnosis of tuberculosis, when other means of diagnosis (e.g., culture, BAL) fail to settle the matter, is not available or is time consuming.
