The role of mri and cect in evalutaion of oral cavity malignancy and its staging

Oral malignancies constitute over 30 % of malignancies in India. This study was conducted to determine and discuss in detail in the role played by Magnetic Resonance Imaging (MRI) and Contrast Enhanced Computed Tomography (CECT) in the staging of oral cavity malignancy. The study provides invaluable information on sensitivity, specificity and other important statistical data of MRI in diagnosing each of the criterion used for TNM staging of oral cavity malignancy. Comparing histopathological staging with imaging staging, MRI showed an astonishing equivalence and compliance with histopathological staging while CECT showed mild discordance with respect to histopathology.
