Cerebral ventricular size in children: a two-dimensional ultrasonic study.

The width of the bodies of both lateral ventricles was studied in 833 children using B-mode echography. It could be accurately measured in 99.9% of those under the age of 2, 94% of these 2 to 5, and 65% of those 6 to 12. The normal lateral ventricular ratio or LVR (width of body of LV/0.5 X internal skull diameter) was 0.24-0.36, but there was a borderline area and the upper part of this range (0.34-0.36) included some cases of early hydrocephalus. In 72% of the children with a head circumference greater than the 98th percentile, the LVR was 0.24-0.36. The greatest transverse diameter of the atrium of the normal lateral ventricle in children appears to be 10 mm, that of the normal third ventricle 5 mm. A water-delay system is described as being superior to a contact system for B-mode echoencephalography.

Cross sectional visualization of the normal heart by the UI Octoson.

The UI Octoson can provide accurate compound and simple scan cross sectional views of the heart. Sections taken in the transverse, sagittal, and other planes normal and parallel to the long axis of the heart are useful for providing full information that may be obtained by the examination. The views allow the visualization and measurement of most major structures of the heart, giving a more complete description of the geometry of the heart.

Ultrasonic examination of orbital vasculature.

Patients with orbital varices form a diagnostically important group of those referred for ultrasonic study of orbital proptosis. Two cases are presented in which diagnosis of dilated orbital blood vessels was established by B scan ultrasonography. The echographic appearance of normal and dilated orbital vessels is discussed.

On the measurement and specification of acoustic output generated by pulsed ultrasonic diagnostic equipment.

The method of describing acoustic output generated by pulsed equipment has not been fully formalized and is often inadequately specified. This paper discusses the terms that we have found useful to specify the acoustic output generated by pulsed diagnostic equipment and proposes additional terms that allow a more complete description of irradiation dosage. The application of the proposed specification is illustrated by measurements made on a typical contact echoscope.

The liquid-filled stomach--an ultrasonic window to the upper abdomen.

An ultrasonic window to the upper abdomen is creasted by (a) filling the fasting stomach with methylcellulose suspension, (b) administering glucagon intravenously, and (c) examining the patient prone. Glucagon relaxes the gastric musculature and the prone position allows the stomach gas to rise to the fundus. This enables assessment of the relationships of the stomach to adjacent structures and permits display of structures forming the stomach bed. The equipment used was a commercially available water-delay system with wide-aperture focused transducers. The system gives good resolution and allows the gastric musculature to be distinguished from the mucosa and its overlying mucus.

Ultrasonic visualization of breast cancer.

Ultrasonic examination of the breast with grey scale echography gives considerable information about the composition of the constituent tissues. This information alone is sometimes of major assistance in the management of the individual patient, particularly in young women with nodular breasts due to dysplastic changes. The method is complementary to the more commonly used visualization techniques and should be considered, particularly in young women, as the first imaging technique to examine palpable masses in the breast, prior to the utilization of ionizing radiation.

Round window ultrasonic treatment of Meniere disease.

The neurosensory structures within the vestibular labyrinth of the inner ear are selectively irradiated with ultrasonic energy to alleviate the vertiginous symptoms of Meniere disease. However, correct application and coupling of the ultrasonic transducer to the inner ear is essential for maximum transmission of energy into the vestibule. The importance of assessing the results of long-term postoperative treatment is demonstrated by a change in the success rate that decreased by approximately 10% when the results obtained within the first 12 months of treatment were compared with those after four years. In this investigation, 32 patients were treated by the round window approach between 1970 and 1972, and after four years it was found that 72% of these were successful in relieving the giddiness symptoms.

Ultrasonic echography in the diagnosis of abdominal disease.

The place of two-dimensional ultrasonic echography in the diagnosis of surgical diseases of the abdomen is outlined, and illustrative cases are described. The method is safe and can be repeated as often as required. It does not replace radiological or radionuclide examinations, but complements those techniques.

Detection and classification of liquid-filled masses in the breast by gray scale echography.

Gray scale ultrasonic visualization of the breast is a simple and safe technique for the detection of liquid-filled masses. Cysts and enlarged ducts as small as 2 mm in diameter can be reliably detected with a greater accuracy than is possible with any other imaging technique. The ultrasonic examination provides considerable information about the nature of the constituent tissues, and this information alone is often sufficient for a determination of the correct treatment.
