  1. T/B ratio: ratio between the average value in tumour to the average value in background liver tissue. Tpeak/B ratio: ratio between the average value of the five hottest voxels in tumour to the average value in background liver tissue. The late static scan was performed after 2 h in patients #1–4 and after 3 h in patients #5–10
  2. n.d. not determined because of major respiratory artefacts
  3. *P ≤ 0.05 when compared to Tpeak/B ratio static 1 h
