Quality assurance in radiographic imaging included in the film marking procedure.

Quality assurance for the radiographic processing can only be obtained by the aid of a continuous densitometric control. A method is described which uses a densitometric step wedge included in the marker equipment. It gives a constant radiation dose to the marking area. The step wedge is exposed simultaneously with the film marking. Disturbances in the radiographic procedure can thus immediately be detected.

Scintigraphic spleen volume calculation.

An uncomplicated scintigraphic method for estimation of the spleen volume is described. Two films individually exposed with the gamma camera represent the basis for calculation according to the same principle as used for the heart volume. By the use of Co indicators a distance reference is obtained. No extra arrangements for the patient are necessary and the examination is performed during the conventional liver-spleen scintigraphy with 99Tcm colloid.

Effect of somatostatin on intestinal motility.

The effect of somatostatin on intestinal motility has been investigated. The demonstrated inhibition of the motility has proved to be suitable for performing double contrast examinations of the small intestine, particularly as the tolerability to somatostatin is better than to other comparative substances.

Effect of 16,16-dimethylPGE2 on gastric emptying and intestinal transit of a barium-food test meal in man.

The effect of 140 mug of 16,16-dimethyl PGE2 on gastric emptying and intestinal transit of a barium-food mixture has been studied in 8 healthy male volunteers. The propagation of the test meal was followed from the stomach to the colon by fluoroscopy wit repeated photograph ic recording. It was found that this analog significantly enhanced the rate of gastric emptying in most subjects, and the food-contrast medium also appeared sooner in the colon following the prostaglandin analog. In addition, the duodenum and the first part of the jejunum had a flaccid and dilated appearance on several occasions after administration of prostaglandin. The more rapid emptying of the stomach after administration of the prostaglandin analog is probably explained by a decreased duodenal resistance towards the gastric outflow; the earlier appearance of contrast in the colon could partly be due to the more rapid gastric emptying following administration of the prostaglandin analog.
