Figure 1

Forty-nine-year-old man with good local response. A: Isodose distribution and region of interests (ROIs): Left panel: Isodose distribution on center section of radiation treatment planning. Red: 45 Gy; orange: 40 Gy; yellow: 30 Gy; green: 15 Gy and blue: < 15 Gy. Right panel: ROIs on MRI before RT: red: tumor with strongest enhancement; yellow: non-tumor liver parenchyma receiving 30 Gy; green: non-tumor liver parenchyma receiving 15 Gy; blue: spleen; B: T1 weighted contrast-enhanced MRI before RT (left panel, the site corresponding to the right panel of (A) and after RT (right panel). Arrows indicate tumor margins; C: Time Intensity Curve of ROIs before RT (left panel) and at week 2 of RT (right panel). Red: tumor; yellow: 30 Gy; green: 15 Gy; blue: spleen. The curve of spleen is deviated after pause for respiration due to interference by lung perfusion. The initial spike due to refocusing artifact will not be counted into analysis.
