Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 2
Abstract
Introduction-Tuberculosis is one of India major public health problems. Though it’s treatable, but still umpteen number of people are afflicted every year with high morbidity and mortality. Early diagnosis is the essence in the management of pulmonary tuberculosis to prevent further progression of disease and permanent damage by fibrosis. The objectives of our study are: 1) To evaluate spectrum of pulmonary abnormalities on HRCT in patients with suspected PTB but with both normal and abnormal chest radiograph. 2) To determine the value of HRCT in predicting disease activity in Pulmonary Tuberculosis. 3) To determine the pattern of HRCT findings in active & inactive Pulmonary Tuberculosis. Material and method This prospective study in which data has been collected from 66 suspected patients of pulmonary tuberculosis from August 2015 to November 2016 who were referred to the department of radio diagnosis, GRMC, Gwalior from department of medicine and department of chest TB for evaluation. Well informed consent was obtained and each suspected patient of pulmonary tuberculosis underwent chest X ray using MARS 50/FC/ALLPOSE, ALLENGER and HRCT using a 128-slice volume scanner (SIEMENS SOMATOM Definition AS+: 95157) and sputum smear examination for AFB. Images were assessed for pattern and distribution of lung abnormalities. Result: Male preponderance was noted with majority of them belonging to 50-59 yr of age group.Majority of patients belong to active tuberculosis with a percentage of 57.5%(56+1.5%),next was relapsing tuberculosis.Final diagnosis of active tuberculosis correlates well with sputum examination which was 100% accurate.X RAY chest diagnosed active TB in 22 cases and all were AFB positive on sputum examination.Sputum smear examination is investigation of choice for diagnosis of TB,but the sensitivity is low .HRCT is helpful in differentiating active vs inactive TB better than plain chest radiograph and recognizing extent of pulmonary TB. Conclusion: HRCT can be beneficial in certain cases, imparting crucial information for the diagnosis and management of the disease. HRCT is advocated if tuberculosis is suspected clinically and the chest X-ray findings are normal or inconclusive; for authentication of diagnosis and discernment of activity
