This text is a practical reference manual on clinical imaging and essential radiology procedures. The majority of the text is a problem-oriented guide to diagnostic imaging of specific diseases, disorders and traumatic injuries of the head and spine, chest, abdomen, pelvis and extremities. For each disorder, the text lists the underlying mechanism; the symptons, signs and differential diagnosis; the indications, techniques and possible results of various imaging studies; the problems and pitfalls that may be encountered in imaging; and the therapeutic issues that need to be addressed after imaging. The latter portion of the text gives instructions for performing 20 radiology procedures. The manual also provides essential information on anatomy, drug dosages, intravenous contrast agents, radionuclides and radiopharmaceuticals, and treatment of contrast reactions.
