Brain Tumor Treatment
In the majority of cases, brain tumors are treated by surgery, alone or in combination with other treatments, such as radiotherapy or chemotherapy.
Before treatment, physicians utilize PET/CT scan results to guide treatment decisions by separating a tumor as being high-grade, low-grade or benign, based on the degree of FDG uptake. A baseline PET/CT scan provides physicians with pretreatment information concerning the extent of disease, which can be compared after treatment with follow-up scans to determine whether treatments have been effective.
PET/CT imaging is a good tool for physicians to use to help determine the grade of the cancer, locate distant metastases, determine the best treatment approach, and assess if the treatment was effective.
A PET/CT scan can show where tumor cells are growing, which helps physicians determine the best course of treatment.
