Abstract
AIM & OBJECTIVES: The aim of this study was to assess the efficacy of cone-beam computed tomography (CBCT) sialography imaging in the evaluation of normal ductal anatomy along with various salivary gland pathosis. MATERIALS AND METHODS: This study comprised of 15 archival CBCT images of patients with signs and symptoms of salivary gland pathologies. A proposed algorithm for evaluation was used to assess and interpret the CBCT images. Four blinded experts manipulated and evaluated the images and scores were given for the interpretation of the images according to the proposed algorithm. Analysis of the resulting data was performed to evaluate the concordance among interpretations. Finally the results were tabulated in “Microsoft Excel” and was evaluated according to consensus and statistical analysis based on “Chi square test”. RESULTS: The results proved to have inter-observer concordance between the radiologists in interpreting the normal ductal anatomy and various salivary gland pathologies. Assessment of normal ductal anatomy such as primary duct, secondary duct and parenchyma showed no significant inter-observer variability. Abnormal salivary glands findings such as the presence of sialolith, strictures, acinar pooling and space occupying lesions showed similar results between the observers except that of ductal dilatation, which proved to have inter-observer variability between the radiologists. Hence by, CBCT sialography proved to have superior diagnostic value in revealing the ductal architecture and in the detection of salivary gland pathosis. CONCLUSION: The diagnostic value of CBCT sialography in obstructive salivary gland diseases with demonstration of the ductal architecture of the gland along with the assessment of salivary gland abnormalities was superior. It is a novel technique for imaging major salivary glands by combining the benefits of the sialography with the versatility of the CBCT.
