“…30 patients with an oncologic history scheduled to undergo whole body clinical PET/CT were recruited prospectively to participate in a whole body PET/MR examination as part of a PET/MR-PET/CT comparison study (24). Myocardial SUV information from the thoracic component of these examinations was analyzed retrospectively.…”

“…145 In the case of cardiac PET/MRI scans, the m-map based on the Dixon sequence has been compared with CT scans and validated, obtaining excellent PET standardized uptake value correlation between CT-based and MRI-based AC. 146 An additional relevant issue is the motion which is necessary to apply to the m-map for image reconstruction, not to incur into inaccuracies close to moving organs. This point can be of special importance for lesions in the lungs, whose uptake can be greatly degraded if the m-map is not registered according to the breathing motion for lesions moving close to the boundary between soft tissue and air (regions with very different attenuation coefficients).…”

The combination of positron emission tomography (PET) and MRI has attracted the attention of researchers in the past approximately 20 years in small-animal imaging and more recently in clinical research. The combination of PET/MRI allows researchers to explore clinical and research questions in a wide number of fields, some of which are briefly mentioned here. An important number of groups have developed different concepts to tackle the problems that PET instrumentation poses to the exposition of electromagnetic fields. We have described most of these research developments in preclinical and clinical experiments, including the few commercial scanners available. From the software perspective, an important number of algorithms have been developed to address the attenuation correction issue and to exploit the possibility that MRI provides for motion correction and quantitative image reconstruction, especially parametric modelling of radiopharmaceutical kinetics. In this work, we give an overview of some exemplar applications of simultaneous PET/MRI, together with technological hardware and software developments.
