The aim of this study is to evaluate the significance of the high-resolution computed tomography (HRCT) modality for the diagnosis of PTB, in comparison to culture test.<\/jats:p><\/jats:sec>Material and methods<\/jats:title>Thoracic HRCT images of the study population, comprising 124 patients clinically suspected for PTB with smear and culture reports, were analysed for sensitivity and specificity of the HRCT test. Features of active PTB were centrilobular nodules, \u2018tree-in-bud\u2019 pattern densities, macro-nodules, consolidations, cavitary lesions, ground-glass opacities, and miliary nodules.<\/jats:p><\/jats:sec>Results<\/jats:title>Among the study population, 108 cases presented HRCT features of active PTB and the remaining cases were negative but had presented a\u00a0few features mimicking PTB. As inferred from positive culture test results, 106 cases had active PTB, the remaining cases were culture negative for PTB. False-positive (FP) or \u2018type I\u00a0error\u2019 cases, and false-negative (FN) or \u2018type II error\u2019 cases were ascertained by Bayes\u2019 theorem. Sensitivity (true positive rate) and specificity (true negative rate) of HRCT test were 0.8125 and 0.8571, respectively.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>For proper diagnosis the predictive capability, as two values of \u2018a\u00a0posteriori probability\u2019, was computed; the mean value of \u2018a\u00a0posteriori probability\u2019 for HRCT was 0.6358. When its culture test was positive, the HRCT test was 69.56-92.85% efficient in ascertaining positive results with a\u00a0sample; on the other hand, when its culture test was negative it was 66.66-100% efficient for a\u00a0negative result. Thus, the HRCT test is considerably dependable.<\/jats:p><\/jats:sec>","DOI":"10.5114\/pjr.2020.93697","type":"journal-article","created":{"date-parts":[[2020,4,20]],"date-time":"2020-04-20T21:46:26Z","timestamp":1587419186000},"page":"125-131","source":"Crossref","is-referenced-by-count":4,"title":["Radiological significance of high-resolution computed tomography for elderly pulmonary tuberculosis patients \u2013 an analysis with culture test"],"prefix":"10.5114","volume":"85","author":[{"given":"Niranjan","family":"Sahu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Somadatta","family":"Das","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rabindra Nath","family":"Padhy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3061","published-online":{"date-parts":[[2020,3,6]]},"reference":[{"key":"ref-1145776","doi-asserted-by":"crossref","first-page":"1809","DOI":"10.2169\/internalmedicine.50.5198","article-title":"Relationship between computed tomography findings and nutritional status in elderly patients with pulmonary tuberculosis","volume":"50","author":"Okamura K","year":"2011","unstructured":"Okamura K, Nagata N, Kumazoe H, et al.
