 Results: Among all undergoing scans, 177 True Positives, while 07 False Positives. Out a 139 scan-negative patients, 6 (False Negative) had culture, whereas 133 (True no (p=0.001). Overall sensitivity, specificity, positive predictive value, negative value Paranasal 96.72%, 95.0%, 96.20%, 95.68% 95.98%,respectively.
