Dr. Gerard Ahern (MBBS) is Clinical Anatomist and Academic Coordinator (University of Notre Dame), Honorary Senior Fellow in Anatomy (University of Melbourne), Member–Board of Examiners (Royal Australian and New Zealand College of Radiologists), Honorary Associate Professor (Oceania University), Tutor and Lecturer (Royal Australasian College of Surgeons), and Co-author of the best-selling bookGeneral Anatomy.

Mr. Maurice Brygel (MBBS, FRACS) is a General Surgeon (specializing in hernial and anorectal surgery), Founder and Director (Melbourne Hernia Clinic), Author of the pioneering Video Book of Surgery, Designer and Teacher (‘Surgical Office Skills Workshops for General Practitioners’), Tutor and Postgraduate Lecturer (Monash University), and Senior Adjunct Lecturer (Monash Division of General Practice).

The diagnostic process is dependent on good clinical skills. But a differential diagnosis can be narrowed or a clinical suspicion confirmed by proper use of imaging. This should not involve a ‘fishing expedition,’ where the clinician replaces clinical skills with a series of investigation forms. If the imaging is normal, where do you go? Back to the patient of course, to repeat the clinical assessment, thus wasting valuable time and effort.

There are many principles involved in reading imaging of any type. The tyro clinician needs to develop his or her knowledge of these principles, including understanding how the images were made in the first place. In this section, the modalities of x-ray, computed tomography scan, magnetic resonance imaging, and ultrasound are broken down into their production, tissue properties, tissue densities, views, and techniques. Other modalities, such as radionucleotide or positron emission tomography scanning, are represented in the images but not detailed in the introduction—their production and reading are relatively simple to understand.
