Role of multidetector computed tomography and magnetic resonance imaging in evaluation of buccal mucosal neoplasms

Background: Buccal mucosa cancers are increasingly common among younger individuals, primarily due to tobacco usage. Accurate staging is essential for effective treatment planning. This study evaluates the role of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in assessing buccal mucosa neoplasms. Methods: This prospective study included 25 patients from Great Eastern medical school and hospital over a 12-month period. All patients underwent initial clinical examination followed by CT and MRI scans. CT scans were conducted using a GE 16-slice MDCT scanner, and MRI scans were performed with a 1.5-T unit. Imaging results were correlated with histopathological findings. The TNM classification system was used for disease staging. Results: CT and MRI demonstrated high sensitivity (98%) in detecting bone erosion and invasion into the infratemporal fossa. MDCT effectively identified the extent of bone involvement, while MRI provided detailed soft tissue contrast, aiding in the evaluation of surgical outcomes. Imaging accurately identified key features impacting staging and treatment, including involvement of the retromolar trigone, tongue, masticator space, bones, neurovascular bundles, lymph nodes, and distant metastases. Conclusions: MDCT and MRI are non-invasive, cost-effective tools critical for the staging and management of buccal mucosa cancer. Early and accurate imaging significantly improves treatment planning and prognostication. Both modalities play complementary roles in assessing disease extent and guiding clinical decisions.
