Validation of FDG-PET Segmentation Tools for Tumor Delineation by Correlation of CT- and FDG-PET Volume Measurements With Histopathology of Nodal Metastases of Head and Neck Carcinomas.

Validation of FDG-PET Segmentation Tools for Tumor Delineation by Correlation of CT- and FDG-PET Volume Measurements With Histopathology of Nodal Metastases of Head and Neck Carcinomas.

Various methods of FDG-PET signal segmentation will be validated by correlation of histopathologically measured tumor dimensions in lymph node dissection specimens of head-and-neck cancer patients.

Inclusion Criteria:

• All patients with N+ squamous cell carcinoma of the head and neck, planned for neck dissection.
• Age >18 years.

Exclusion Criteria:

• Pregnancy.
• Women breast feeding
