Fig. 6

Representative images of a patient. a Transaxial image of contrast-enhanced CT. The swollen paraaortic lymph node is shown. b, c 2-h and 4-h images with [18F]FMISO. d, e 1-h and 2-h images with [18F]DiFA. Tracer uptake to the lymph node metastasis of rectal adenocarcinoma is clearly detected in all images. The contrast at 1 h and 2 h with [18F]DiFA (TMR = 1.25 and 1.37, respectively) is better than that at 2 h with [18F]FMISO (TMR = 1.09) and equivalent to 4-h [18F]FMISO (TMR = 1.44)
