Fig. 3

Patient measurements. Examples of 19F-MRS three-dimensional chemical shift imaging measurements in five metastatic colorectal cancer patients treated with TAS-102. The anatomical images of the regions of interest are shown, in this case the liver metastases, and an overlay of 19F spectra in red and blue. Blue spectra indicate the spectra measured in liver metastases, red spectra indicate the spectra measured in other liver tissue(s). In all images no distinct metabolic signals (SNR > 5.5 or > 4.8) were observed at around 10 ppm, where trifluridine should be visible. The spectra in this figure are shown in absolute mode. P1–P5 patients 1–5
