Imaging Techniques Of The Cns Of The Neonates

There has been increasing interest in neonatal neurology, especially since imaging techniques were introduced in the neonatal ward. Looking at the natural history of imaging techniques, we can identify three main axes of its development. Logically, it was first essential to image the brain morphologically. For this purpose, computed tomography was initially used, followed by ultra sound. However, to improve the quality of the images, magnetic resonance imaging was introduced. Major features of ultrasound and magnetic reso nance imaging are their safety and lack of ionization. Morphological imaging techniques have proved to be insufficient to ex plain the mechanisms underlying CNS injuries. Thus, it was essential to develop functional techniques to assess cerebral hemodynamics and oxy genation. The use of Doppler ultrasound, PET scanning, SPECT scanning and, more recently, NIRS have widened our knowledge of general neurolog ical problems. Finally, to achieve our goal of attaining a better understanding of CNS injuries, it is important to assess cerebral cellular metabolism. Magnetic resonance spectroscopy was introduced to achieve this goal. We hope that this book links these different techniques in order to widen our horizon. The future is promising and bound to provide further develop ments, which however can only be understood if we grasp the present level of development.

The advent of magnetic resonance imaging (MRI) has made a major impact on neuroimaging, revolutionising diagnosis and management of central nervous system (CNS) disorders. With contributions from experts in the field this text covers MRI of the brain, orbit and spine for the paediatrician and neurologist. A Mac Keith Press Publication

Cranial ultrasonography is the most important, accessible, patient friendly, and cheapestneuroimaging technique on the neonatal ward. It provides important information on brain maturation in the (preterm) neonate and enables the detection of frequently occurring brain anomalies. In this second edition of Neonatal Cranial Ultrasonography, the focus is on the basics of the technique, from patient preparation through to screening strategies and the classification of abnormalities. Many new ultrasound images have been included to reflect the improvements in image quality since the first edition. Essential information is provided about both the procedure itself and the normal ultrasound anatomy. Standard technique is described and illustrated, but emphasis is also placed on the value of supplementary acoustic windows. The compact design of the book makes it an ideal and handy reference that will guide the novice but also provide useful information for the more experienced practitioner.

This is a comprehensive "atlas" of the brain of the newborn infant as depicted by high-frequency ultrasound. For ease of use, the volume is arranged into distinct parts. Coverage begins with "echo-anatomy", then proceeds through congenital anomalies, in utero acquired brain damage, and perinatal injury. Where relevant, corresponding CT or MRI pictures are provided. Additional topics covered include Doppler imaging and the measurement of echodensity. Throughout the work, the authors maintain a focus on relevance for the practicing physician. Thoroughly illustrated with over 600 halftones and color plates, this is an impressively up-to-date and comprehensive book.

The novel aim of this book is to illustrate the MR imaging features of the fetal and the neonatal brain by matching prenatal and postnatal images for a wide range of neurological abnormalities. The focus is on both conventional and advanced MR imaging techniques, including high-resolution MR autopsy of the fetal brain. During the past ten years, neuroradiological evaluation of the neonatal and the prenatal brain has advanced tremendously. However, even though they are intrinsically related, these two critical stages in brain development are usually studied and presented separately. In order to have a sound understanding of neonatal brain diseases, detailed knowledge of prenatal brain pathology is immensely helpful; conversely, knowledge of neonatal brain disease is a prerequisite for understanding many fetal brain lesions. Written by experts in the field, Perinatal Neuroradiology will be of value for neuroradiologists and pediatric radiologists, as well as obstetricians and neonatologists.

Vast experience has been gained over the past decade in safely transporting, monitoring, and imaging neonates, a highly vulnerable patient group. Technological advances in MRI hardware such as higher field strength systems, multi-channel coils, higher gradient performance, and MR compatible incubators with integrated antennae laid the ground for more detailed, higher resolution anatomical MR imaging. This issue provides separate reviews on the use of MR imaging in the evaluation of encephalopathy, postmortems, spinal dysraphia, and inflicted brain injury as well as neonatal neuro MR imaging and MR-guided cardiovascular interventions.
