Pancreatic ultrasound--a systematic approach to scanning technique.

The pancreas remains one of the more difficult organs to visualize but ultrasound can be successful in nearly 90% of patients. A systematic technique for identifying and delineating the pancreas is described and has been verified on over 500 patients to date. The success of the technique depends on an accurate knowledge of the vascular relations of the pancreas and on correct adjustment of the ultrasound equipment. This paper is intended to help ultrasound practitioners achieve both these ends.

Place of ultrasound and radiography in obstetrics.

In the two years after an ultrasound service was introduced at this hospital obstetric referrals for abdominal radiography decreased by over 55%. Most of these were for estimation of fetal maturity. Out of 349 such patients subjected to radiography in 1976, 176 had already been examined by ultrasound; in only four did radiography appear to influence management. We believe that if a satisfactory ultrasound scan is obtained before 30 weeks of gestation subsequent radiological estimation of fetal maturity is unjustified. Radiography may still be necessary, however, for diagnosing fetal abnormalities.

Distinction of benign from malignant ovarian cysts by ultrasound.

The ultrasonic characteristics of benign and malignant cystic ovarian tumours have been reviewed. The value of each of eight different ultrasonic features has been assessed and the specificity of each for confirmation or exclusion of malignancy is indicated. In combination they permit correct differentiation in 91 percent of cases.

Preparation of the patient for abdominal ultrasound scanning.

The value of dietary restriction and laxatives both separately and in combination for the reduction of bowel gas has been investigated and compared with unprepared patients. No significant difference was found between the results from prepared and un-prepared patients.

A comparison of grey-scale image recording systems.

There is currently a rapid rise in the variety of image recording systems and recording media available for use with ultrasound and CT scanners. We have evaluated nine different systems and ten recording media and have compared their cost, convenience and performance. The choice of system in a particular department depends upon many factors, especially the number of images recorded and the reasons for recording them. We suggest that a busy department will probably require one of the more expensive automatic devices since these are the most convenient to use and have the lowest cost per image.
