The rapid improvements made in equipment for B-mode gray-scale ultrasonography during the 1970s enable the radiologist-ultrasonographer to study the brain of an infant with a portable device that gives images of high resolution without using ionizing radiation. Numerous articles published during the last five years described the evolution of equipment and techniques used to study normal as well as pathologic changes within the crania of newborn infants. Drs Babcock and Han concisely have summarized their experience with and knowledge of cranial ultrasonography, as well as the experiences of others in this field.
For physicians and technologists who deal with imaging procedures, the authors included sections that discuss the main types of ultrasound equipment presently available, as well as describe and illustrate the techniques the authors use at their institution to obtain high-quality images. Some sections deal with normal and pathologic changes as they appear on ultrasonograms. Illustrations of the degree
