Elastography, the science of creating noninvasive images of mechanical characteristics of tissues, has been rapidly evolving in recent years. The advantage of this technique resides in the ability to rapidly detect and quantify the changes in the stiffness of soft tissues resulting from specific pathological or physiological processes. Ultrasound elastography is nowadays applied especially on the liver and breast, but the technique has been increasingly used for other tissues including the thyroid, lymph nodes, spleen, pancreas, gastrointestinal tract, kidney, prostate, and the musculoskeletal and vascular systems. This book presents some of the applications of strain and shear-wave ultrasound elastography in hepatic, pancreatic, breast, and musculoskeletal conditions.
This practical guide is a compilation of firsthand expertise from leading authorities around the world on the use of ultrasound elastography. The stiffness or softness of the imaged tissue derived from elastography provides accurate radiologic diagnosis for disease processes including cancer, inflammation, and fibrosis. It is an efficacious and accurate diagnostic imaging modality that helps avoid invasive biopsies. The first two chapters cover basic fundamental principles of elastography, with subsequent chapters exploring pathology-specific utilization. The authors cover the extensively validated and implemented use of elastography for diffuse liver disease, and diseases of the breast andthyroid gland. They also discuss the potential benefits and limitations for the prostate, spleen, pancreas, kidneys, musculoskeletal system, salivary glands, lymph nodes, and testes. The book concludes with a chapter on potential future applications of this ever-evolving technology. Key Highlights Discussion of key differences between strain elastography and shear wave elastography by individual organ systems Clinical pearls on how to accurately perform elastography and tips for avoiding false-positive or false-negative results Case studies elucidate the targeted use of elastographic findings by specific pathology Illustrations in the breast and liver chapters demonstrate precise transducer techniques MRI elastography as an emerging and safe assessment tool, primarily for the diagnosis of liver disease, with emergent potential for additional organs This book provides key knowledge on visualizing quantifiable differences in tissue elasticity and applying this data to improved treatment strategies for diverse pathologies. It is essential reading for radiologists, sonographers, and imaging technicians.
This comprehensive reference covers the principles and techniques used in performing breast elastography, an innovative imaging technology that can dramatically reduce the need for biopsies. The book begins with an introduction of the techniques, followed by sections on how to perform each technique and methods of interpretation, and concludes with more than 60 detailed case studies. Key Features: Includes case studies covering a wide range of breast pathologies and illustrating the use of all available elastography techniques to help radiologists obtain the best images for each pathology Covers all methods of breast elastography, including sheer wave and strain wave Contains more than 200 high-quality color images that demonstrate how to perform each technique Breast Elastography is an essential reference for all radiologists, residents and fellows, and sonographers involved in breast imaging and evaluation.
The comparison between methods, evaluation of portal hypertension and many other questions are still open issues in liver elastography. New elastographic applications are under evaluation and close to being used in clinical practice. Strain imaging has been incorporated into many disciplines and EFSUMB guidelines are under preparation. More research is necessary for improved evidence for clinical applications in daily practice. The Special Issue published papers on recent advances in development and application of Ultrasound Elastography.
With the aid of an extensive series of high-quality images, this atlas describes all the potential applications of elastosonography in routine clinical practice. After a brief introduction on technical and physical aspects, the diagnostic benefits of elastosonography in a range of settings are illustrated with the aid of numerous representative cases. The coverage encompasses pathologies of the liver, spleen, pancreas, kidney, breast, thyroid, testis, musculoskeletal system, and vascular system. In addition, helpful correlations with imaging appearances on ultrasound and computed tomography are included. Elastosonography is a powerful, relatively new diagnostic technique that assesses the elasticity of tissues as an indicator of malignancy. Readers will find this book to be an excellent aid to use and interpretation of the technique.
Ultrasound Elastography for Biomedical Applications and Medicine Ivan Z. Nenadic, Matthew W. Urban, James F. Greenleaf, Mayo Clinic Ultrasound Research Laboratory, Mayo Clinic College of Medicine, USA Jean-Luc Gennisson, Miguel Bernal, Mickael Tanter, Institut Langevin – Ondes et Images, ESPCI ParisTech CNRS, France Covers all major developments and techniques of Ultrasound Elastography and biomedical applications The field of ultrasound elastography has developed various techniques with the potential to diagnose and track the progression of diseases such as breast and thyroid cancer, liver and kidney fibrosis, congestive heart failure, and atherosclerosis. Having emerged in the last decade, ultrasound elastography is a medical imaging modality that can noninvasively measure and map the elastic and viscous properties of soft tissues. Ultrasound Elastography for Biomedical Applications and Medicine covers the basic physics of ultrasound wave propagation and the interaction of ultrasound with various media. The book introduces tissue elastography, covers the history of the field, details the various methods that have been developed by research groups across the world, and describes its novel applications, particularly in shear wave elastography. Key features: Covers all major developments and techniques of ultrasound elastography and biomedical applications. Contributions from the pioneers of the field secure the most complete coverage of ultrasound elastography available. The book is essential reading for researchers and engineers working in ultrasound and elastography, as well as biomedical engineering students and those working in the field of biomechanics.
This richly illustrated book provides a comprehensive overview of the use of current ultrasound techniques, including contrast-enhanced ultrasound and ultrasonic elastography, in the diagnosis of breast disease. The advantages and pitfalls of the various imaging modalities are identified, and it is explained how combined use of the modalities – multiparametric ultrasound – aids diagnosis and in particular assists in the differentiation of benign and malignant disease. Readers will find detailed description and illustration of the imaging appearances of age-related features (including in children and adolescents), the most important benign diseases, different forms of breast cancer, mammary gland pathology in the contexts of pregnancy and female reproductive system disease, chest gland pathology in males, and recurrent and metastatic disease. In addition, ultrasound-guided breast interventions and imaging of breast implants are discussed. Specialists in ultrasound diagnostics, radiologists, oncologists, and surgeons will all find this topical book to be both interesting and helpful in daily clinical practice.
This book is an up-to-date and comprehensive guide to all the common thyroid disorders that may be seen by internists, endocrinologists, nuclear medicine physicians, and endocrine surgeons. While the fundamentals of thyroid hormone function and regulation in health and disease are well covered, the primary focus is on the clinical approach to thyroid disease, with detailed coverage of both initial diagnosis and management and the role of imaging. Because most endocrine diseases are chronic and lifelong, special emphasis is placed on long-term management and the common pitfalls that may be encountered by the clinician. The editors are internationally acknowledged leaders in the field of thyroid disease and have gathered an outstanding team of authors, all of whom are also highly expert in their respective areas, but who, equally importantly, write in a clear and lucid style. The numerous isotope scan and ultrasonographic images ensure that the book will serve as a valuable reference atlas to which the physician will return again and again.
