Contribution of 18F-Fluoro-ethyl-tyrosine Positron Emission Tomography to Target Volume Delineation in Stereotactic Radiotherapy of Malignant Cranial Base Tumours: First Clinical Experience
Figure 3
A 47-year-old female patient (patient no. 2) with a recurrent auditory canal cancer located at the base of the skull. FET-PET shows infiltration into the left parotideal gland to a lesser extent than assumed from the MRI. The MRI/CT volume is delineated in red and the PET volume in green. The additional PET information is included in the initial treatment fields (magenta). The boost volume could be reduced as delineated in turquoise.
