James Stirling, Joemon John, Geoff Charles-Edwards, Jane MacKewn, Gary Cook As an integrated system, hybrid positron emission tomography/magnetic resonance imaging (PET/MRI) is able to provide simultaneously complementary high-resolution anatomic, molecular and functional information, allowing comprehensive cancer phenotyping in a single imaging examination. In addition to an improved patient experience by combining two separate imaging examinations and streamlining the patient pathway, the superior soft tissue contrast resolution of MRI and the ability to acquire multi-parametric MRI data is advantageous over computed tomography (CT). For gastrointestinal cancers this will improve tumor staging, assessment of neoadjuvant response and of the likelihood of a complete (R0) resection in comparison to PET/CT.
