During the past five years, extraordinary advances in imaging technologies have made the diagnosis of disease and injury faster, more accurate, safer, and more cost effective. This new edition of Squire's Fundamentals of Radiology describes and illustrates these new techniques to prepare medical students and other radiology learners to provide optimal and up-to-date diagnostic imaging of their patients. Not only are new imaging techniques introduced, such as multidetector CT for the diagnosis of pulmonary embolism, diffusion-weighted magnetic-resonance imaging of stroke, and molecular imaging for the early diagnosis of cancer, but hundreds of new diagnostic images have been included, illustrating the radiological characteristics of disease on state-of-the-art digital radiography, ultrasound, multicetector computed tomography, and magnetic-resonance images. The new edition has been completely revised and updated, yet it maintains the successful organization of the previous edition, presenting imaging concepts in an orderly and comprehensible manner. The interventional radiology chapter now includes vertebroplasty for treatment of painful compression fractures, uterine artery embolization of fibroid tumors, and radiofrequency ablation of malignant tumors. A completely new chapter covers the latest developments in imaging, including virtual colonoscopy, virtual bronchoscopy, three-dimensional ultrasound, fusion imaging with PET-CT (positron emission tomography combined with computed tomography), CT coronary calcium scoring, multidetector CT gated cardiac imaging, functional magnetic-resonance imaging, and molecular imaging.Through all its editions Squire's Fundamentals of Radiology has been the standard introductory text for medical students studying radiology in courses and clerkships. It is also now widely recommended reading for radiology residents and for residents and fellows in other fields of medicire. As Director of the Core Radiology Clerkship at Massachusetts General Hospital for more than twenty-five years, Dr. Novelline has trained thousands of medical students and residents, and all of the material included in this new edition has been student tested for clarity and comprehensibility.
