Fig. 5From: Metabolic activity via 18F-FDG PET/CT is predictive of microsatellite instability status in colorectal cancerA a 45-year-old male had right colon cancer. 18F-FDG-PET/CT scans showed intense accumulation of 18F-FDG in the tumor (arrow; MTV,37.26; TLG,494.44). IHC analysis revealed MSI-H(MLH1(−) and PMS2(−)) after surgical resection. Scale bars, 100 mm. B a 55-year-old male had sigmoid colon cancer. 18F-FDG-PET/CT scans showed high accumulation of 18F-FDG in the tumor (arrow; MTV, 12.11; TLG,114.91). IHC analysis revealed MSS after surgical resection. Scale bars, 100 mmBack to article page
