​This book describes and illustrates the radiological findings that are characteristic of Crohn’s disease and correlates these appearances with clinical and surgical findings in order to assist the reader in implementing an appropriate diagnostic approach in this complex disease, which often differs from patient to patient. All of the modern imaging modalities and techniques are covered, including ultrasound, multidetector row computed tomography (MDCT), magnetic resonance imaging (MRI), and combinations of MDCT and MRI with enteroclysis and enterography. The current value of X-ray and the role of endoscopy are also examined. Care is taken to cover specific patient groups, including pediatric patients, those with perianal disease or anal fistulas, and patients who have undergone surgery. In addition to surgical approaches, including minimally invasive options, other new therapies are discussed.  The book will be invaluable for diagnostic radiologists, gastroenterologists, and surgeons.
