Unenhanced chest CT shows high sensitivity (86.7%) for diagnosing smear-negative pulmonary tuberculosis, aiding accurate detection.
For patients with +2 acid-fast bacilli smears, chest CT achieves a specificity of 81.3% and sensitivity of 47.4%, indicating a balanced diagnostic approach.
Diagnostic accuracy of chest CT varied by smear grade, highlighting the importance of tailored imaging strategies for pulmonary tuberculosis.
Significant correlation exists between key CT features and microbiological confirmation of pulmonary tuberculosis, supporting CT's diagnostic utility.
