In compiling this textbook on the exciting novel imaging modality of PET/MRI, the editors have brought together a truly international group of experts in the field. The book is divided into two parts. The first part covers methodology and equipment and includes chapters on basic molecular medicine, contrast agents, MR attenuation and validation, and quantitative MRI and PET motion correction. The second part of the book focuses on clinical applications in oncology, cardiology, and neurology. Imaging of major neoplasms is covered in a series of individual chapters. Further chapters address functional and metabolic cardiovascular examinations and major central nervous system applications such as brain tumors and dementias. This book will be of interest to all radiologists and nuclear medicine physicians who wish to learn more about the latest developments in this important emerging imaging modality and its applications.

Currently there is no shortage of challenges and opportunities for PET instrumentation and quantitative imaging techniques. Molecular imaging technologies are leading to a revolutionary paradigm shift in health care and clinical practice. This issue reviews recent advances in PET instrumentation as well as volume correction strategies and strategies for motion tracking and correction, scatter compensation techniques, and attenuation correction techniques.

This issue of PET Clinics focuses on Radiotracers, and is edited by Drs. Neil Vasdev and Abass Alavi. Articles will include: PET/CT detection of HER2-positive metastases in patients with 89Zr-DFO-trastuzumab; uPAR-PET with 68Ga-NOTA-AE105: first clinical experience with a novel PET ligand; 64Cu-FBP8: A fibrin-targeted probe for imaging of thrombus; Imaging of synaptic density in the brain via synaptic vesicle glycoprotein 2A (SV2A) with a novel biomarker [11C]UCB-J; Neuroimaging of stress sensitive and neuroinflammatory targets in mood disorders; Impact of MR-based PET motion correction on the quantification of PET kinetic parameters in simultaneous cardiac PET-MR; Multimodal studies of the contributions of amyloid and tau burden to neurodegeneration in AD, FTD and Non-AD tauopathies; Imaging of prostate-specific membrane antigen (PSMA) using [18F]DCFPyL; Ga-68 GRPR antagonist imaging; and more!

This issue examines PET-MRI with evolving but potentially competing technologies. The guest editors have put together an extremely timely issue as practicing radiologists are increasingly curious about the role of diffusion weighted imaging with MRI as a competing or a complementary technique to PET.
