    1) Comparison of the overall sensitivity of chest computed tomography andchest x-rayindetecting pulmonarytuberculosis among bacteriologically confirmed cases. 2) Comparison of the sensitivity of individual findings (i.elymphadenopathy and lung parenchymal abnormalities) on chest computed tomography andchest x-ray indetecting pulmonarytuberculosis among bacteriologically confirmed cases. Material and methods: 100 patients with microbiologically confirmed pulmonary TBreferred to the Department of Radiodiagnosis and Imaging for chest x ray and chest CT scan were included in thestudy. Results: Overall sensitivity of chest CT scan and chest X ray to detect pulmonary tuberculosis were 78% and 63% respectively and show significant difference. Chest CT scan detected pulmonary T.B. with overall lymphadenopathy, mediastinal lymphadenopathy, nodular opacities, collapse, pleural effusion/thickness and cavity/abscess better than chest X ray, however there was no significant difference between chest X ray and chest CT scan in detection of pulmonary T.B. with consolidation/G.G.O, hilar lymphadenopathy, bronchiectasis. Conclusions: Chest X-ray was not as sensitive as Chest CT scan in detecting mediastinal lymphadenopathy, nodule/nodular infiltration, collapse, pleural effusion and cavity, so in a clinically relevant setting with a Chest X-ray negative for these findings Chest CT scan should be considered, but if these findings are depicted well in Chest X-ray, Chest CT scan may not add further clinically significant information over the Chest X-ray
