We thank Dr. Uno for his interesting comment on our work. We also hypothesized that a longer examination time may yield very interesting results, as he correctly pointed out. However, there is the issue of keeping a patient stuck in a MR system for five hours, as we wanted to avoid repositioning after each scan. On the other hand, we feel that the use of ionizing radiations for this kind of evaluation is nowadays suboptimal, as exposure can be hardly justified.
