Abstract
Squamous cell carcinoma makes up the most common group of malignant head and neck tumors. As these tumors originate from the mucosal surface, they are accessible for inspection, mirror examination or endoscopy. Endoscopy is the gold standard, facilitating histologic verification, but requiring anesthesia. The aim of imaging modalities like CT and MRI is to accurately assess the infiltration depth into deeper compartments, which can not be directly visualized. Prior to surgery, about 80% of these patients undergo cross-sectional imaging procedures. Multislice spiral CT (MSCT) with the capability of isotropic volume data sets improved the diagnosis and staging of the tumors substantially. Image planes adapted to the specific anatomical demands can be created to optimally display the tumor site and tumor spread along specific pathways. Many patients present advanced stage cancer at the initial consultation. These patients suffer from swallowing and respiratory problems. Thus, it is of great importance to minimize examination time in order to reduce impairments of image quality due to motion artifacts. Despite the excellent soft tissue contrast of MRI, a significant number of examinations are substantially degraded by motion artifacts.
