Background/introduction
Before the invention of advanced technologies, conventional radiogram (Caldwell or Water's views) was considered to evaluate Para Nasal Sinus (PNS). However, simple radiogram has poor sensitivity and specificity in demonstrating anatomy and in detection of pathology. Failure to detect sinusitis can lead to serious complications, such as cellulitis and osteomyelitis.
After the advent of advanced technologies in radiological imaging, CT scan is considered as the gold standard test for evaluation and accurate diagnosis of various pathological conditions of PNS .As CT scan shows multiple sections...

Conclusion and recommendations
Digital tomosynthesis [DT] has emerged as a technical and feasible imaging modality. It is a form of limited-angle computed tomography that allows reconstruction of multiple section images from a set of projection data acquired over a limited range of X-ray tube angles.
We made an attempt in this study to compare the image quality [anatomy visualization and pathology detection] and radiation dose in X-ray PNS, and PNS Digital tomosynthesis with CT PNS as standard of reference and determine the diagnostic accuracy of DT in the...
