Synopsis
Transfontanellar Doppler imaging was until recently an emerging new diagnostic modality that was not widely used in clinical practice. Dr. A. Couture and Dr. C. Veyrac have pioneered and incessantly developed the tech and neonatal brain scanning until it has now been matured into an nique of prenatal indispensable tool for the correct management of infants. Building upon the technical progress in the manufacturing of scanning probes and ultrasonic equipment, the authors have been able to accumulate a unique and exceptional body of knowledge on fetal and neonatal brain scanning. Their book provides exquisite information not only on the normal neonatal brain, but also on the various pathological conditions and malformations involving the fetal and neonatal brain as provided by ultrasound examination. The book contains numerous illustrative examples, selected from the outstanding personal files of the authors. Transfontanellar Doppler imaging, because of its great impact on the management of neonates suspected of brain abnormalities, should be available to all pediatric and general radiologists involved in brain scanning in the pediatric age group. They, and also neurologists and neurosurgeons, will find this volume a unique source of information and knowledge. I congratulate the editors on their outstanding performance and I wish this volume great success within the medical community. Leuven ALBERT L. BAERT Preface Alain Couture belongs to the breed of pioneers. This requires several unusual traits: orginality, tenacity and vision, and of course hard work.
From the Back Cover
This book examines in detail the role of transfontanellar pulsed and color Doppler imaging in the fetus and neonates. After an introductory chapter on the technical aspects of Doppler ultrasonography, its use in the normal neonate is considered. Results of the hemodynamic evaluation of 491 newborns aged from 32 weeks of gestation to 9 months by means of pulsed and color Doppler are reported. Normal values of the resistive index as determined by this technique are documented, and systolic, diastolic, and mean velocities in seven different vessels are presented. It is concluded that Doppler ultrasonography enables reliable analysis of arterial and venous velocities. Subsequent chapters examine the use of transfontanellar Doppler imaging in a variety of commonly encountered pathological conditions, including intracranial hemorrhage, hydrocephalus, hypoxic-ischemic brain damage, pericerebral collections, sinus thrombosis, intacranial infections, and brain malformations. The message of this book is that transcranial Doppler imaging has an important role to play both in the explanation of fetal and neonatal brain injury and in the clinical evaluation of brain damage.
