A. Normal anatomy B. Imaging techniques: CT & MR C. Key Concepts i. Submandibular & sublingual spaces communicate: Diving ranula, sublingual abscess ii. Approach to the retromolar trigone iii. Approach to root of tongue iv. Muscular atrophy - pseudolesions & remote pathology v. Nodal analysis relating to the oral cavity vi. CT imaging technique variations: Puff cheek CT for gingivobuccal sulcus mass, angled gantry imaging vii. Multimodality assessment – ultrasound for tongue SCC
