Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 8
Abstract
Introduction: Introduction of HRCT in radiology field has improved the diagnosis of many respiratory diseases, since pulmonary TB is major concern for India, role of HRCT in diagnosis for disease activity is very pivotal. Study aimed to determine the pattern of HRCT findings in active and inactive Pulmonary Tuberculosis and the value of HRCT in predicting disease activity in pulmonary tuberculosis. Material and methods: A retrospective correlational study was conducted over a period of six months on 50 patients from September 2016 till April 2017, referred to our department of Radiology at AMC MET Medical College in Maninagar, Ahmedabad with suspected pulmonary tuberculosis. The patients were subjected to HRCT on Phillips MX 16 and the patterns of disease activity and inactivity were analysed. These features were then correlated with Sputum AFB examinations. Results: In our study, 27 patients were males and 23 were females. Average age at presentation was found to be about 44 years. Tree-in-bud appearance, Ill-defined nodules, Consolidation were found to have a high predictive value in diagnosing disease activity. Mediastinal adenopathy, pleural effusion and Ground Glass Opacity were statistically insignificant. Conclusion: Although chest radiography is the foremost imaging technique in the evaluation of pulmonary tuberculosis. HRCT can be important in the diagnosis and management as it can differentiate active from inactive disease with greater sensitivity. Ill-defined nodules, consolidation and tree-inbud were best indicators of active disease. Combination of indicators was found to improve the predictive value.
