Assessment of Tumor Volumes in Skull Base Glomus Tumors Using Gluc-Lys[18F]-TOCA Positron Emission Tomography

In patients with glomus tumors, Gluc-Lys[18F]-TOCA PET helps to reduce interobserver variability if an appropriate threshold for tumor segmentation has been determined for institutional conditions. Especially in patients with recurrent tumors after surgery, Gluc-Lys[18F]-TOCA PET improves the accuracy of GTV delineation.
