This book explains how radiology can be a powerful tool for establishing the diagnosis of many internal medicine diseases. It is organized in the classic fashion for internal medicine books, with eleven chapters covering the different internal medicine specialties. Within these chapters, more than 450 diseases are considered. For each disease, radiological and clinical features are displayed in images and high-quality digital medical illustrations, and those differential diagnoses are identified that can be ruled out by imaging alone. In addition, the pathophysiology underlying the radiological features is described, explaining why a particular sign is seen on MR images, CT scans, or plain radiographs. The book will serve as an excellent radiological atlas for internal medicine practitioners and family physicians, showing disease presentations that may be hard to find in standard medical textbooks and explaining which imaging modalities are likely to be most informative in particular patients
RESPIRATORY SYSTEM The complex of organs and tissue which are necessary to exchange blood carbon dioxide (CO 2 ) with air oxygen (O 2 ) is called the respiratory system. It consists of structures, which function as ducts, and which together are called the conductive portion of the respiratory system structures which form the respiratory portion of the respiratory system, in which the exchange of CO 2 and O 2 is occurring and the parts of the thoracic musculo-skeletal apparatus and specialisations of the lung which allow the movement of air through the respiratory system - the ventilating mechanism . ........ Nasal Cavity The Nasal cavity is divided into three structurally and functionally different parts. The vestibules (the first ~1.5 cm of the conductive portion following the nostrils) are lined with a keratinised stratified squamous epithelium. Hairs, which filter large particulate matter out of the airstream, and sebaceous glands are also present. At the t
