Aim: To evaluate and correlate role of Multidetector CT in evaluation of neck masses. Material and Method: The study was carried out at the Department of Radiodiagnosis and Imaging, N.S.C.B. Subharti Medical College on 55 patients presenting with neck masses and they were subjected to Multidetector CT evaluation. The patients were informed about the radiation exposure in the examination. The patient’s progress was followed up clinically with repeat serial Multidetector CT scans when necessary. The cytopathological and/or histopathological examination reports of all patients were collected from the pathology department and were used as a gold standard for comparison. Diagnostic statistics such as sensitivity, specificity, positive predictive value, negative predictive value and accuracy has been used to find the correlation of CT scan with final diagnosis. Results: The final diagnosis was confirmed by Histopathology /FNAC and non-nodal masses accounted for 51% of total neck masses (28/55) and nodal masses accounted for 49% of the total neck masses (27/55). The p value for lesions imaged using CT was statistically significant i.e. <0.01 which implied that there was a strong correlation of the imaging finding on MDCT vs. FNAC/Histopathology.Conclusion: We conclude that MDCT has a high diagnostic sensitivity for detecting both benign and malignant masses, Specially of the pharynx and larynx and has equal sensitivity for detecting extra nodal spread.
