Figure 1From: Clinical implications of determination of safe surgical margins by using a combination of CT and 18FDG-positron emission tomography in soft tissue sarcoma The Setting of Regions of interest (ROIs) from the tumor border. After the tumor border was defined by contrast-enhanced MRI, regions of interest (ROIs) were set at intervals of 1 cm for the 5 cm long region from the tumor border in a direction free of biological barrier. SUV data by preoperative FDG-PET/CT in these regions were analyzed using VISIO KEOPSYS VIEWER (CODONICS: USA). Measurement was performed in at least two directions for each case.
