By O. Ratib, M. Schwaiger (auth.), Osman Ratib, Markus Schwaiger, Thomas Beyer (eds.)

This new venture on PET-MR imaging in oncology comprises electronic interactive software program matching the instances within the publication. The interactive model of the atlas relies at the most up-to-date internet commonplace, HTML5, making sure compatibility with any desktop working method in addition to a devoted model for Apple iPad.

The publication opens with an advent to the foundations of hybrid imaging that will pay specific consciousness to PET/MR imaging and traditional PET/MR acquisition protocols. quite a lot of illustrated medical case experiences are then provided. every one case learn incorporates a brief medical historical past, findings, and educating issues, through illustrations, legends, and comments.

The multimedia model of the publication comprises dynamic video clips that permit the reader to flick thru sequence of rotating 3D photographs (MIP or quantity rendered), reveal mixing among puppy and MR, and dynamic visualization of 3D picture volumes. the films may be performed both constantly or sequentially for higher exploration of units of images.

The editors of this state of the art booklet are key opinion leaders within the box of multimodality imaging. Professor Osman Ratib (Geneva) and Professor Markus Schwaiger (Munich) have been the 1st in Europe to begin the medical adoption of PET/MR imaging. Professor Thomas Beyer (Zurich) is an the world over well known pioneering physicist within the box of hybrid imaging. person scientific instances offered during this publication are co-authored through prime overseas radiologists and nuclear physicians specialists within the use of puppy and MRI.

Subsequently, deformation fields are generated and incorporated into the PET reconstruction [51, 82–85]. Thus, the use of periodic MR navigator signals in conjunction with a 4D model of the human torso may help to correct for motion-induced image degeneration in PET/MR data following 4D-MR-AC, which would be a major advantage over CT-AC. PET/MR Safety Combined PET/CT has been clinically very successful and may well serve as a benchmark for the development of PET/ MR. However, despite the success of PET/CT there are also 2 PET/MR Instrumentation shortcomings in the use of CT as the anatomical complement to PET.

In addition, parallel transmission benefits PET/MR through the reduction of local SAR, allowing for significant increases in scanning speed [76]. Image Quality and Quantification A major advantage for PET/MR versus MRI is the high specificity of PET as well as its relative and absolute quantification of the radiotracer bio-distribution. This becomes possible after the implementation of several corrections on the PET data related to ionising radiation measurements; namely, radioactive decay, the attenuation and scatter of photons in matter and random registered coincidences 35 a b Fig.

Such artefacts propagate in the MRAC map in a relatively arbitrary fashion, depending on the location and extent of the artefact (Fig. 6). Metal artefact reduction sequences (MARS) can be used to reduce the size and intensity of susceptibility artefacts from magnetic field distortion [111]. However, currently only manual corrections may be available. Apart from attenuation correction, scatter correction may also need some consideration in PET/MR. Although the standard methodology performs very well for most clinical situations, on certain clinical settings when patient set-up may differ from PET/CT, this difference may impact on scatter correction accuracy.
