Molecular And Cellular Mr Imaging

The ability of molecular and cellular imaging to track the survival, migration, and differentiation of cells in vivo as well as monitor particular gene expression in living subjects is rapidly moving from the research laboratory into daily clinical settings. The interdisciplinary nature of the field mandates a constant dialogue among molecular and

Magnetic resonance imaging (MRI) is a non-invasive imaging tool that provides excellent soft tissue contrast with submillimeter spatial resolution. However, its potential of therapeutic interventions and diagnostic applications can be limited by the low sensitivities in detecting cellular, molecular and metabolic changes. Development of novel MR contrast agents with desired targeting or drug delivery capabilities for cellular and molecular imaging may be beneficial for higher sensitivity and specificity. Spectroscopic imaging at high-field MRI may be advantageous in identifying and quantifying metabolic changes with increased signal-to-noise ratio and spectral resolution. In this book, novel techniques for cellular, molecular and metabolic MRI are investigated and demonstrated to be valuable in various applications.

This book provides a comprehensive overview of the importance of molecular imaging in multiple myeloma, with detailed explanation of its clinical impact. Other important features are the definition of criteria that will aid PET/CT interpretation; identification and explanation of the most frequent pitfalls; a brief overview of the advantages and limitations of DWI MR imaging, still an experimental technique in multiple myeloma; and examination of the possible role of emerging PET tracers. When appropriate, clinical cases are used to illustrate key teaching points. All physicians involved in oncological imaging should regularly reassess and update their routine practice in the evaluation of multiple myeloma patients. This is especially true now, given the recent clarification by the International Myeloma Working Group (IMWG) of the criteria for bone damage requiring therapy and the emerging data supporting the role of the newer functional imaging techniques in predicting outcome and/or evaluating response to therapy. In this challenging context, Molecular Imaging in Multiple Myeloma will be of high value for nuclear medicine physicians, radiologists, and hematologists.

Despite the tremendous growth in the field of magnetic resonance imaging (MRI) evidenced in the initial phases of its development in the early twentieth century, scientific focus has shifted in recent years toward the study of physiology and pathophysiology that span the spatial scales of the molecule, cell, tissue, and organ. Intensified research activities over the past 15 years have justified efforts toward molecular and cellular imaging, dual-modality imaging systems, real-time acquisitions, dedicated image processing techniques and applications, and the critical evaluation of their potential translational value for use in the clinic. The integrative focus on molecular-cellular-tissue-organ function and dysfunction has taken a primary role in modern, personalized medicine, and it is envisaged to continue to do so, as accumulated knowledge from basic and clinical science work continues to elucidate molecular, cellular, and physiological/pathophysiological pathways and mechanisms. In this scientific effort, MRI continues to play a critical and synergistic role from the perspectives of basic science, diagnosis, and clinical interventional/therapeutic approaches. Within the realm of the current role of MRI in modern medicine, this book summarizes state-of-the-art direct and derived MRI methodologies and approaches as applied toward the assessment of cellular and organ function and dysfunction. The contributions in this effort are not excessive but few, comprehensive, and distinguished and of high quality. The topic areas can be generalized to find applications in other scientific areas and span both brain and cardiac applications, extending interest to wider audiences.

Image-based biomarkers that report on specific cell phenotypes in the body are highly valued for disease detection and monitoring cytotherapies. Towards this need, there is sustained scientific interest in fluorine-19 (19F) magnetic resonance imaging (MRI) for in vivo molecular–cellular imaging applications. The attraction of 19F tracer MRI is its ability to produce pure ‘hot-spot’ images, an absence of false-positive signals, robust quantification, and tracer safety. For molecular–cellular applications, fluorine MRI does not require a pre-scan prior to tracer administration, thus offering several advantages over metal–ion-based proton (1H) contrast-agent approaches. Key applications of 19F MRI include cell tracking, inflammation detection, and biosensing. Fluorinated imaging tracers can also serve as therapeutic agents or drug-delivery vehicles. Over the past decade, the field of 19F MRI has seen remarkable innovation in tracer designs and detection methods as well as the realization of its clinical potential. This book is an interdisciplinary compendium detailing cutting-edge science and biomedical research in the emerging field of 19F MRI and includes technical issues, such as pulse sequence considerations and limits of detection of the techniques; synthesis of novel 19F MRI tracer agents; inflammation, cancer, and stroke imaging; regenerative brain repair; theranostic nanomedicine; and clinical perspectives. The book will appeal to investigators involved in MRI physics, biomedicine, immunology, pharmacology, and probe chemistry as well as general readers.
