This is the second, updated and extended edition of a well-received book that offers a comprehensive overview of ultrasonographic imaging of acute and chronic gastrointestinal diseases, including acute abdomen, appendicitis, diverticulitis, inflammatory bowel diseases, neoplasms and masses, infections, malabsorption syndromes, and rare conditions. The value of ultrasound in each disorder is clearly explained and illustrated, and limitations identified. Information is also provided on recent technical developments and ultrasound applications that are likely to become of increasing importance, such as functional and 3D ultrasound, contrast agents and intraoperative ultrasound, elastography, and transperineal ultrasound. The authors are all distinguished experts in the topics they address. Ultrasound of the Gastrointestinal Tract will be a helpful guide in daily practice not only for radiologists but also for gastroenterologists, abdominal surgeons, pediatricians, and oncologists.

This practical volume is intended for all radiologists, gastroenterologists, and surgeons who are responsible for, or interested in, the diagnosis and care of patients with diseases of the anal and perianal region. After an introductory section focusing on surgical, MRI, and US anatomy, up-to-date clinical and therapeutic information is provided on the full range of perianal inflammatory conditions, with special attention to Crohn's disease, ulcerative colitis, and sexually transmitted diseases. Physical and surgical examination is carefully discussed, with consideration of limitations, results, clinical needs, and the questions likely to be posed of imaging. The subsequent three sections provide detailed information on the different imaging modalities: transanal and transperineal ultrasound, contrast-enhanced MRI, and CT. Techniques, diagnostic accuracy, common and unusual disease patterns, artifacts, and pitfalls are clearly presented.
