Magnetic Resonance Imaging-guided High Intensity Focused Ultrasound has recently been suggested as an alternative treatment modality for pancreatic cancer that is non-invasive, and may be suited for treatment in cases where surgery is not an option. However, using proton resonance frequency shift based thermometry in this area is highly challenging, because of motion and air in the digestive tract near the pancreas. We have shown experimentally that patient preparation by filling the stomach and duodenum with juice can be a pragmatic solution for more precise temperature monitoring during MR-HIFU therapy particularly in the head of the pancreas.
