In current clinical practice, a patient usually undergoes a diagnostic computer tomography (CT) scan for evaluation of specific presenting symptoms. The presence of cancer is then confirmed by a diagnostic biopsy or at surgical exploration by histopathologic analysis. Suspicious finding on the diagnostic CT scan may be followed by an 18F FDG (Fluorodeoxyglucose radiolabeled with 18F) positron emission tomography (PET) scan. In a majority of cases, these pre-operative CT and PET scans are used to identify the approximate location of the tumor(s) before surgical intervention. Surgery remains the most effective means of treating solid malignancies despite advances in chemotherapy and radiation therapy [1].
