The use of contrast media is required in many applications of modern diagnostic imaging, regardless of which modality is employed. This book aims to provide a different approach to contrast media, which are discussed essentially from the point of view of the radiologist. However, the referring physician will also derive much valuable information from the volume, in that it is elucidated to which contrast media particular groups of patients may be exposed, and the possible consequences of such exposure. Comprehensive sections are devoted to iodinated contrast media and to the contrast media employed in magnetic resonance imaging and ultrasonography. The latest agents to become available receive due attention, and adverse reactions are also covered in detail. A final section considers the use of contrast media in nuclear medicine.
