This book presents a vast collection of radiologic images of cases seen in a very busy emergency room. It encompasses common and very unusual pathology and every imaging modality. The book is divided into four parts on pathology of the vascular system, chest, abdomen and pelvis and reproductive organs. Images obtained with the modalities that best depict the abnormality in question are presented, with marking of the salient pathology and explanation of the abnormal imaging features in concise captions. Whenever possible, differential diagnosis is covered using further images and guidance is also provided on selection of additional modalities to confirm the diagnosis. The book will help residents to analyze different diseases and relate pathophysiology to imaging and assist students in appreciating what is abnormal. It will be a useful guide for the busy practicing radiologist and aid clinicians in understanding the complexity of these cases and delivering better focused treatment.
