Phantoms to simulate gastrointestinal artefact in MPI

摘要

We thank Panagi et al. [1] for their thoughtful approach toconstructing a liver phantom for myocardial perfusion imaging(MPI). There are a number of sources within the gastrointestinalsystem which may be responsible for artefactsin MPI (in terms of motion, scatter and attenuation). Thestomach and bowel are others [2]. Would they require similarprinciples of design?
