Magnetic resonance imaging of head and neck tumors
Effective therapy of head and neck tumors depends on accurate assessment of tumor size, extent, and nodal spread. Physical and endoscopic examination remain the foundation of the clinical staging procedure. They are the most accurate methods of assessing mucosal involvement by tumor. Deep extension of tumor cannot be visualized directly, but can often be inferred by alterations in mucosal contours. Direct or indirect visualization of the vocal cords remains the most effective method of evaluating laryngeal function. In addition, physical examination is the easiest method of evaluating lymphadenopathy, although it is somewhat limited by node location and interobserver variation.
