by Dr. Jan. J. Smulewicz Ultrasound imaging has reached a stage of
sophistication where by diagnostic information can be gained
without discomfort to the patient and with complete absence of
morbidity and mortality. The procedure is quick, safe, noninvasive
and in many instances can supersede and obviate more time-consuming
procedures requiring catheterization, injection of a contrast
material, and radiographic imaging. In obstetrical problems the
danger of ionizing radiation to the fetus is eliminated. In
debilitated and very ill patients this simple and painless method
becomes the procedure of choice. Unique features of ultrasound
equipment allow for pinpoint local ization oflesions and direct
visual guidance of percutaneous puncture techniques for aspiration
and biopsy. The accuracy of ultrasound guided punctures and the
absence of side effects make this modality far superior to
percutaneous invasive techniques performed with other imaging
systems. Renal cyst puncture and amniocentesis are but two of the
procedures in which ultrasonic guidance is the method of choice. v
Dr. Hassani has throughly explained and carefully explored the wide
variety of exam inations available with ultrasound. The large
volume of material and the clear interpre- tion makes this book of
great interest to all of the medical profession. In addition to the
existing methods available for diagnostic in terpretations, this
method of noninvasive diagnosis should find its way into every
hospital or center where good medical care is provided. JanJ.

by Dr. Nathaniel R. Bronson, 11 This volume serves a two-fold
purpose very nieely. For the ophthalmologist there is a
presentation of the teehniques and results of ultrasonie
examination of the eye and orbit. For the radiologist or general
ultrasonographer the essential oeular anat- omy and pathology are
deseribed with these findings. Unlike eon- ventional x-rays or
statie general body ultrasonograms, the exami- nation of the eye by
real-time ultrasonography must be done by an examiner with
extensive personal knowledge of the eye and the orbit, both
anatomieally and pathologieally. The student must realize that the
Polaroid photographs ean only show an example of what was
transiently seen, such as spot films taken during fturo- seopy.
This is further eomplieated by the poor reproduetion by Polaroid
films of the aetual gray sc ale seen during the examination.
Considerable work has been done to prepare this text. The author
has done elinieal ultrasonography of many eyes and presents the
findings of his experienee. As in most fields of medieal diagnostie
work this experienee is essential to aehieve the best results. The
beginner in ophthalmie ultrasonography is eneouraged to work with
known pathology. Fortunately, pathologie ehanges in the eye vii

detachment is an ideal case with which to start. CAT scanner.
by Dr. Donald L. King The past decade has seen the ascent of
ultrasonography to a preeminent position as a diagnostic imaging
modality for obstetrics and gynecology. It can be stated without
qualification that modern obstetrics and gynecology cannot be
practiced without the use of diagnostic ultrasound, and in
particular, the use of ultrasonogra phy. Ultrasonography quickly
and safely provides detailed, high resolution images of the pelvic
organs and gravid uterus. The quality and quantity of diagnostic
information obtained by ultra sonography far exceeds anything
previously available and has had a revolutionary impact on the
management of patients. High resolution static images permit the
intrauterine diagnosis of fetal growth retardation and fetal
abnormalities. In addition to tradi tional images, newer dynamic
imaging techniques allow observa tion of fetal motion, cardiac
pulsation, and respiratory efforts. The use of ultrasonography for
guidance has greatly augmented the safety and utility of
amniocentesis. One of the great virtues of diagnostic ultrasound
has been its apparent safety. At present energy levels, diagnostic
ultrasound appears to be without any injurious effect. Although all
the availa ble evidence suggests that it is a very safe modality
and that the benefit to risk ratio is very high, the actual safety
margin for its use Vll as yet remains unknown. As a consequence,
practitioners are urged to limit its use only to those situations
in which genuine clinical indica tions exist and real benefit to
the patient is likely to result."
