Diagnostic radiology plays a vital role in patient management and all clinicians need to be able to recognize the radiological appearances of many medical conditions. Not only are traditional imaging techniques important, but newer techniques such as interventional radiology, computed tomography, magnetic resonance imaging, nuclear medicine, and ultrasound are increasingly important in clinical practice. The interpretation of radiological images is also an integral part of professional examinations within general surgery. This book covers all modalities in radiology, providing a guide to the principles of plain radiographic film interpretation and an understanding of the roles and limitations of more complex imaging across general surgery. The use of contrast agents, radiation dosage, and guidance on the interpretation of some imaging modalities such as the chest and abdominal radiograph, intravenous urogram, and barium studies are included. The material is presented through the discussion of 101 fully-illustrated cases which take a question and full answer format.
