Foreword
Interpretation of the emergency CT brain scan is a visual art. Comparison is made between the image in front of you and a reference image. For the experienced person this reference image is imprinted in the mind; therefore comparison is quick. For the beginner you can either carry several examples of every possible appearance of normal and abnormal scans to compare with or read this book! This book contains a few proven ways of quickly learning to interpret a brain CT scan, irrespective of your previous experience.
The radiologists experience is related to the number of hours he or she has spent looking at CT scans. The radiologist conveys his evaluation of the CT scan in words that often come in a particular sequence and combination. This book is about helping you to rapidly understand and confidently use the same language used by the radiologist.
The difference is that whereas the radiologist aims for perfection, you aim for functionality. For instance, it will be acceptable and clinically safe if an intern physician looks at the brain CT scan in Fig. and can make a judgement of the urgent action required like ABCs ( A irway, B reathing and C irculation with c- s pine) and call a neurosurgeonimmediately. This is lifesaving and efficient without the need for a long list of differential diagnoses before deciding on this action. Since the first edition, image presentation and storage has moved from films to digital format. The author has seamlessly introduced this new platform in explaining the concepts of interpreting the emergency brain CT scan. Therefore, the skill to act decisively about the CT scan in front of you can be acquired in a very short time. And the author has reduced that time to a few hours using this book!

Preface
An illustrated guide for ER physicians, trauma surgeons, primary care physicians, residents, medical students, nurses and other care givers
Across emergency rooms all over the world, thousands of patients are referred for brain CT scans daily. A radiologist often has to interpret the scan or a consultation has to be made to a neurosurgeon to review the scan. Most of this happens late at night and is a significant source of discontent. Thus, having frontline physicians to be proficient in interpreting the emergency brain CT scan improves the efficiency of the whole pathway of care and is potentially lifesaving as time is of the essence for many patients with severe brain injury or stroke.
Underlying all of the above and the primary reason for writing this book is that the skill required to determine an immediate life-threatening abnormality in a brain CT scan is so basic and can be learned in a short time by people of various backgrounds and certainly by all physicians. Indeed, the emergency head CT scan is comparable to an electrocardiogram in usefulness and most definitely as easy to learn. This book is therefore written for caregivers the world over to demystify the emergency CT brain scan and to empower them to serve their patients better. It is obvious to me from the responses from people I have had opportunity to teach this subject that not only is there a desire to learn this basic skill but also people learn it quickly and wonder why it has not been presented so simply before.
It is to fulfil this need and to reach a wider number that I have put together these basic, proven steps in the interpretation of emergency brain CT scan for ER physicians, trauma surgeons, primary care physicians, nurses, medical students and other primary caregivers.
Since the first edition, the transition from X-ray film-based delivery of images to electronic delivery (e.g. PACS) has become more widespread. However, the examination of individual slices to reconstruct a three-dimensional image remains the cornerstone of CT imaging; hence this volume has retained the present format while recognizing the ability of the non-radiologist provider to manipulate individual images including enlarging and changing the window level. This technology is by no means universal and therefore not assumed in the description of images in this text.
