Mark is also involved in teaching medical students through his roles as a Clinical Tutor Associate for the University of Edinburgh and lecturer for the Edinburgh Student Radiology Society. He graduated with distinction from the university of Southampton, and has published and presented research work extensively and internationally in the fields of pharmacology and medical education. Whilst working in Edinburgh he was part of the leadership team developing a near peer teaching programme, where by junior doctors, throughout south east scotland, were both trained to teach, and delivered teaching across every hospital in the area.

To further enhance the clinical relevance, each case has 5 clinical and radiology-related multiple-choice questions with detailed answers. These are aimed to test core knowledge needed for exams and working life, and illustrate how the X-ray findings will influence patient management. One of the keys to X-ray interpretation is practice, practice and more practice.

The bonus X-ray chapter provides over 50 further X - ray cases to help consolidate the reader's knowledge and provide an opportunity to practice the skills they have learnt. In addition to these four core chapters the introductory chapter covers the very basic science behind X-rays, the relevant legislation controlling X-rays and tips on how to request radiology examinations. Additionally a chapter is devoted to other important imaging investigations, such as computed tomography CT , magnetic resonance imaging MRI and ultrasound, covering the details of what the examinations involve, their common indications and contraindications and key imaging findings.

This book teaches systematic analysis of Orthopaedic X Rays. The reader is asked to interpret the X-ray before turning over the page to reveal a model report accompanied by a fully colour annotated version of the X-ray. All cases provide high quality, fully annotated, fully reported images, meaning that even beginners can follow the thinking of an expert.

This book teaches systematic analysis of ChestX Rays. This book teaches systematic analysis of Abdominal X Rays. The Unofficial Guide to Medical Research, Audit and Teaching will teach you the skills expected of students and today's graduates beyond just clinical medicine. It contains convenient checklists for critical appraisal which may be used as a day-to-day reference by professionals, as well as suggestions for audits, and tips for teaching effectively.

This book covers all the non-clinical competencies that will make you an excellent doctor, and highly competitive on the job market. This book is an informed, educational and abundantly illustrated guide to the imaging knowledge that medical students in the clinical years of their undergraduate studies will be required to get to know, understand and recall in order to negotiate successfully their finals exams.
