The evolution of policy in education has been very important in determining the direction and the rate of its spread in Nigeria. As one moves from one area or era to another, weak policy or lack of policy has created unforeseen problems that have had long-lasting consequences that color how much and what type of education was deemed suitable for a milieu. A lack of understanding of the role of policy has been responsible for many failed interventions in education. This book traces the evol...

Since the respiratory airways branch to all parts of the lungs and ready access is provided through the nose or mouth, exploration of these passages for direct visualization or tissue sampling has long been a clinical challenge. This would be particularly helpful in diagnosing those pulmonary diseases that involve the bronchial tree or affect the surrounding lung parenchyma which prove difficult to diagnose or define by indirect methods. The pioneering efforts of Chevalier Jackson in 1918,...

Journalists, always very direct and in search of sensation, essentially asked me two questions on the occasion of this workshop: What were the goals of the meeting? With the improvement of diagnosis through the development of image techniques, didn't the contrast media already have their future behind them? Many answers were provided during the course of the workshop, and in order to best answer the journalists I proposed the following synopsis. 1. Since the 1979 Colorado Springs workshop ...

Clinical Cardiac MRI is a comprehensive textbook intended for everyone involved in magnetic resonance imaging of the heart. It is designed both as a useful guide for newcomers to the field and as an aid for those who routinely perform such studies. The first edition, published in 2004-5, was very well received within the cardiac imaging community, and has generally been considered the reference because of its completeness, its clarity, and the number and quality of the illustratio...

Sleep Medicine is a rapidly growing and changing field. Experienced sleep medicine clinicians and educators Richard B. Berry, MD and Mary H. Wagner, MD present the completely revised, third edition of Sleep Medicine Pearls featuring 150 cases that review key elements in the evaluation and management of a wide variety of sleep disorders. The cases are preceded by short fundamentals chapters that present enough basic information so that a physician new to sleep medicine can start reading pag...

The second volume of Frontiers in European Radiology covers two very promising techniques in diagnostic radiology, namely digital radiography and nuclear mag netic resonance imaging. Leading experts in both fields from Europe and the Unit ed States were invited to give a critical overview; digital fluoroscopy is reported on mainly by American scientists since this technique has been developed primarily in the United States, while the results of nuclear magnetic resonance imaging are pre se...

Magnetic resonance imaging of the heart allows a quick and exact evaluation of global and regional pump function, regional myocardial wall motion, myocardial perfusion and coronary blood flow. Some of these parameters must also be analyzed under stress conditions to identify myocardial ischemia.By combining these functional parameters with high-resolution anatomical images, which are even sufficient to depict the coronary arteries, magnetic resonance imaging has become one of the m...

A general consensus exists,that lumbosacral nerve root compression is the primary cause of sciatica and neurogenic claudication, although humoral and vascular factors certainly play a role as well. This book focuses on imaging the various ways in which nerve root compression can come about, and determining which anatomic features are reliably associated with the production of radicular pain. After a discussion of the nature of radicular pain and related symptoms, spinal imaging techniques ...

MRI is a non-invasive and non-ionizing imaging modality that is perfectly suited for the diagnosis and follow-up of both pediatric and adult congenital heart disease. It provides a large field of view and has the unique ability to depict complex cardiac and vascular anatomy and to measure cardiac function and flow within one examination. MRI is the ideal complement to echocardiography whenever the information provided by the latter is limited. This book has been conceived as a self-teachin...

Every discipline tends to develop its own particular language and ways of communicating. This is true also about the various disciplines that talk about and describe the human voice - particularly as it relates to singing. The aim of this book is to bridge any gaps in communication, foster better understanding of the singing voice and encourage collaboration between those involved in performance, teaching, therapy and medicine. Because there is increasing interest in research in all these ...

This book summarises the ideas of educational theorists and psychologists of the last 60 years, from Elinor Goldschmied to Tina Bruce. It also looks at the important contemporary issues in early years education, from whether boys and girls learn differently to the role of the community in the early years setting.
