Book Description

Most ingested foreign bodies pass through the gastrointestinal tract without a problem. However, both ingested and inserted foreign bodies may cause bowel obstruction or perforation or lead to severe hemorrhage, abscess formation, or septicemia. Foreign body aspiration is common in children, especially those under 3 years of age, and in these cases chest radiography and CT are the main imaging modalities. This textbook provides a thorough overview of the critical role of diagnostic imaging in the assessment of patients with suspected foreign body ingestion, aspiration, or insertion. A wide range of scenarios are covered, from the common problem of foreign body ingestion or aspiration in children and mentally handicapped adults through to drug smuggling by body packing and gunshot wounds. Guidance is offered on diagnostic protocols, and the value of different imaging modalities in different situations is explained. Helpful management tips are also provided. This textbook will prove invaluable for residents in radiology, radiologists, and physicians who are involved on a daily basis, within an emergency department, in the management of patients with suspected ingestion, aspiration, or insertion of foreign bodies.​

Book Description

This book offers concise descriptions of cross-sectional imaging studies of the abdomen and pelvis, supplemented with over 1100 high-quality images and discussion of state-of-the-art techniques. It is based on the most common clinical cases encountered in daily practice and uses an algorithmic approach to help radiologists arrive first at a working differential diagnosis and then reach an accurate diagnosis based on imaging features, which incorporate clinical, laboratory, and other underlying contexts. The book is organized by anatomical organ of origin and each chapter provides a brief anatomical background of the organ under review; explores various cross-sectional imaging techniques and common pathologies; and presents practical algorithms based on frequently encountered imaging features. Special emphasis is placed on the role of computed tomography (CT) and magnetic resonance imaging (MRI). In addition to algorithmic coverage of many pathological entities in various abdominopelvic organs, unique topics are also examined, such as imaging of organ transplant (including kidney, liver and pancreas), evaluation of perianal fistula, and assessment of rectal carcinoma and prostate carcinoma by MRI. Cross-Sectional Imaging of the Abdomen and Pelvis: A Practical Algorithmic Approach is a unique and practical resource for radiologists, fellows, and residents.

Book Description

Netter's Introduction to Imaging, by Larry R. Cochard, PhD, Lori A Goodhartz, MD Carla B, Harmath, MD, Nancy M. Major MD, and Srinivasan Mukundan, JR, MD, makes interpreting normal and abnormal X-ray, CT, and MR images easy by correlating them with crystal-clear Netter illustrations. You'll learn to recognize anatomical relationships in images and apply them to a variety of examples of pathology throughout the body, including the imaging of masses, air, or blood in organs and spaces...fractures, thickening, constriction, and compression...and more. It's an ideal introduction to diagnostic imaging! Visualize anatomical structures and relationships with perfect clarity with the aid of vivid, colorful Netter artwork. The coloring, texture, and idealized emphasis help you interpret relationships between structures and compartments as seen in cross section and in X-rays, CT, and MRI. Develop your ability to better identify pathologies by viewing normal healthy anatomical images and abnormal images. Comparative images reinforce your basic understanding of what normal tissues and anatomy look like and serve as a guide in recognizing disease patterns and processes: atypically large or small organs and compartments, masses, air, or blood in organs and spaces, fractures, thickening, constriction, compression, and more. Understand the principles that underlie X-ray, CT, MR, ultrasound, and nuclear medicine imaging, the use of contrast and angiography. Understand how radiologists apply systematic search strategies in imaging studies of each region of the body.
