CHEST X-RAY DIAGNOSTIC ACCURACY THROUGH HRCT (HIGH RESOLUTION COMPUTED TOMOGRAPHY) IN THE CASES OF INTERSTITIAL LUNG DISEASE

Objective: The research was aimed to find Chest "X - Ray" diagnostic accuracy in the patients of interstitial lung disease through chest HRCT "High Resolution Computed Tomography. Material and Method: This research was cross-sectional which was carried out at Services Hospital, Lahore in Diagnostic Radiology Department (September, 2016 to May 2017). There were a total 137 patients of both genders having clinical suspicion of the (ILD) i.e. interstitial lung disease of age from 20 to 50 years were made to study. Those patients along with h/o past histopathological diagnosis, taking treatment already & women who were pregnant were excluded from study. The patients had chest x-ray & HRCT and findings were recorded in the form of presence or the absence of (ILD). Results: Average age was ranging between 40.21 +/- 4.29 years. Out of 137 subjects, the ratio was as: 79 at 57.66 percent males & 58 at 42.34 percent females. The female to male ratio was "1:1.36". ILD was identified through Chest "X - Ray" in eighty subjects at 58.39 percent patients in which 72 being true +ve had (ILD) & eight being false +ve were without (ILD) on (HRCT). The final sensitivity, diagnostic accuracy of chest x-ray, -ve predictive value, specificity & +ve predictive value in diagnosing (ILD) was found 80.0 percent, 81.02 percent, 90.0 percent, 82.98 percent and 68.42 percent respectively. Conclusion: The research finally concluded that chest x-ray is a simple, economical, non-invasive & easily available alternate choice to (HRCT) along with an acceptable diagnostic accuracy of eighty-one percent in all the diagnosis of (ILD).
