Computed tomographic assessment of squamous cell carcinoma of oral and pharyngeal cavities

Computed tomographic (CT) scans were prospectively obtained on 68 patients with previously untreated stages III and IV squamous cell carcinoma of the oral and pharyngeal cavity. We report herein the results of CT evaluation of primary disease arising in these sites, improvements in contrast-enhancement techniques, and CT assessment of the patient's condition after radiation or chemotherapy treatment.
