Available in PDF, EPUB and Kindle. Book excerpt: This book examines in detail the role of transfontanellar pulsed and color Doppler imaging in the fetus and neonate. After an introductory chapter 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.
