Contributors Foreword
Indeed it is proud privilege for me to write the foreword for the 2nd Edition of IAP Textbook of Pediatric Radiology.
Recent growth in the field of diagnostic radiology has dramatically increased the complexity of this field. Diagnostic imaging has become widely available and plays an increasing role in diagnosis and therapy.
With availability of many modalities and availability of radiology facilities at district and taluka places at time it is found that it leads to the ordering of incorrect imaging studies, duplication of orders, unnecessary requests for follow-up imaging, too many exam orders, and other problems. The risk of radiation hazard is also to be kept in mind while submitting children for any radiological investigations.
Child health and well-being are the core areas of mission statement of Indian Academy of Pediatrics and for that IAP is involved in knowledge upgradation of pediatricians through organizing CMEs, conferences, workshops and publishing books. Earlier IAP Textbook of Pediatric Radiology was published in 2013 and was found to be very successful and popular amongst pediatricians. With the recent growth in the field of diagnostic radiology, it was necessary to publish the second edition of IAP Textbook of Pediatric Radiology.
As president of IAP I am happy that editorial team led by Dr TM Ananda Kesavan and Dr S Venkateswaran worked hard to bring this second edition. The book is written, with general pediatricians in mind, as an alternative to the traditionally large (and hard to learn) reference textbooks. This book does not detail the literature of all disease processes. Instead, it is focused on the most common clinical scenarios encountered in daily practice. It also includes practical imaging techniques and protocols used to address common problems, and can give readers easily accessible tools to aid in reaching a specific diagnosis.
I congratulate the editorial team and contributors and thank them for their contribution. I am sure it will be proved as one of the most popular publications of IAP.

Preface to the Second Edition
“Retain the past and Refresh with new” is the concept we have adopted in this edition. Since the first edition is a Master edition with the excellent proposition of chapters and topics, the essential style and format have been retained and we have added few interesting topics and case scenarios. As a face lifting to previous edition, Dr Mona D Shastri has presented an excellent start up writing about the discovery and evolution of X-rays. Also she has given an outline of radiation hazards, types of X-rays and most important radiographic positions in pediatrics which is easy to understand by any pediatrician. Since the X-ray chest is the most commonly utilized investigation, the advent of Digital chest X-ray and respiratory clinical case scenarios added by Dr S Venkateswaran is an important practical addition in this text. The cardiovascular system by Dr M Zulfikar Ahamed is face lifted by addition of interesting X-rays and cases. The add up cases in Bone and Metabolic diseases by Dr G Vijayalakshmi elevates the chapter to completion. The additional insertion of case scenarios by Dr TM Ananda Kesavan adds color to this edition.
Although many of us are comfortable with new imaging modalities and contemporary techniques, it is not possible with all the patients and with all the pediatricians. The approach in this book provides an effective and cost containing evaluation in a medical environment beset with financial constraints and unfamiliar imaging modalities. For this reason, the text is additionally and especially suited to pediatricians practicing primary care pediatrics and emergency room pediatrics.
We have tried to limit all changes to those that are truly significant in a practical sense, rather than change for the sake of change. It is our hope and belief that a pediatrician with the content of this book will be able to approach sick children professionally with skill and confidence. We hope that this book meets our goals, and we remain grateful for any comments and criticisms that our readers may wish to offer.

Preface to the First Edition
The aim of this Textbook of Pediatric Radiology is to provide valid and vibrant information to practicing pediatricians at all levels especially who are dealing with level one care.
It is an undeniable fact that pediatric radiology differs from adult radiology and many a time even many of the general radiologists and even few of the so called pediatric radiologist may find it difficult to interpret and may feel uncomfortable in arriving at a final diagnosis.
We as pediatricians have an additional advantage of approaching the child based on well-defined clinical symptoms which may suggest limited differential diagnosis and also taking the child's age into consideration, diagnostic possibility may be best explored and our vision may be narrowed down sharply towards better radiological diagnosis.
We have carefully concentrated more on the conventional, day-to-day method of basic radiological approach and restricted our approach to the unfamiliar imaging techniques.
In a true practical sense, the images given and the approaches aimed will be most useful to all of the pediatricians especially in the Indian context of restrained financial background and thus burden of investigation may not be much felt by the parents of sick children.
We have carefully dealt with the most of the acute conditions which are commonly seen in our outpatient clinic, pediatric casualty, PICU, NICU and in our day-to-day chamber practice.
We, the contributors will feel extremely happy if you are able to make a valid diagnosis after going through book and that ray of hope when radiated from you will be the day of success for this book.

Introduction
X-rays are most commonly used radiological investigation all over the world. Most of us are very familiar with chest X-rays (for many people X-ray means X-ray of chest!), because we can interpret it easily, freely available, cheap, and one can repeat it. The only disadvantage is the risk of radiation.
X-rays were discovered way back in 1825 and even now its use has not dimmed. X-rays are electromagnetic radiations. They are produced in a cathode ray tube where fast moving electrons from a filament strike a tungsten anode and the energy is converted into X-rays. When X-rays pass through the body they are absorbed to varying amounts, bone absorbing the most. The X-rays that exit the body are made to form an image on X-ray film, on an activated cassette (computerized radiography) or is directly digitized and is viewed on a computer (digital radiography). The image obtained of the body shows the internal body structures in white, black and shades of gray. Air is black in color as it is least dense, has not absorbed any radiation, and allows the X-rays to pass through easily. Bone and metal are white as they are very dense. Soft tissues like liver and spleen and fluid that may accumulate in the pleural cavity appear white, but not as densely white as bone.
Fluoroscopy using an image intensifier allows real-time imaging using X-rays. In this, the image is intensified and put on a TV monitor. This imaging is useful when motion in internal organs needs to be studied, e.g. respiratory motion in obstructive emphysema. Since radiation dose is high in this, intermittent rather than constant radiation exposure is used.
Fluoroscopy is also used for contrast studies. In this, an opaque medium like barium is used to line and fill hollow internal viscera. Barium is very dense and absorbs X-rays, thus appearing white. Barium can be ingested in Barium swallow and meal or can be instilled into the rectum and colon for a barium enema study. Air is also used as a contrast medium as in double contrast enema for rectal and colonic polyps. Barium enema is given, then evacuated and air is instilled into the colon under fluoroscopic guidance. This clearly brings out barium-coated white mucosal lesions against the black background of air.
Angiography is the study of blood vessels. The contrast media used here are iodine compounds. A peripheral artery is catheterized and contrast is injected into the required branches. Images are timed and taken rapidly and fine vascular detail is obtained in the X-rays. Computerized tomography of blood vessels uses contrast medium, but without invasive catheterization. In magnetic resonance angiography, blood vessels can be studied even without contrast, by computer manipulation.
The quest for better images and more precise diagnoses has led to rapid advancements in the field of radiology. The wide spectrum of modalities that are available in present times, enable us to study the morphology and function of the human body in explicit detail. However, in children almost 75% of questions arising from clinical problems are solved by X-rays and ultrasound. Even when other techniques are used, the X-ray usually serves as guidance to the choice of the next investigative modality (e.g. mediastinal masses discovered in chest X-ray is followed by CT). So X-rays need to be interpreted correctly. This book focusing only on X-ray radiography is a sincere effort aimed at sharpening the X-ray reading skills that will help in solving the majority of daily clinical problems.
It may be felt that imaging is now playing a large part in clinical diagnosis and that final diagnoses are obtained from imaging. While this may be true to a certain extent it should be remembered that clinical history and examination is the base and images have to be interpreted on the basis of clinical findings. Sharpening X-ray interpretation skills will help in mastering the use of the primary investigative modality that will help in diagnostic evaluation and treatment, ultimately for the benefit of the patient.
