Real-time ultrasongraphy is a simple, accurate, noninvasive and potentially valuable means of studying gallbladder size and emptying. The authors calculated ultrasonographically the ejection fraction of 80 cases of normally functioning gallbladder on oral cholecystography, from June 1983 to April 1984, at the department of radiology, Hangang Sacred Heart Hospital. The results were obtained as follows; 1. Ultrasongraphic Ejection Fraction at 30 minutes after the fatty meal was 73.1+-16.85. 2. There was no significant difference in age and sex, statistically.

The CT findings of the adrenal disease in a total of 52 patients were analysed. 39 patients of them wereverified at operation and composed of 22 patients of Cushing's syndrome, 11 patients of pheochromocytoma, 6patients of aldosteronism. The remainder was finally diagnosed on the basis of compelling clinical and biochemical evidence. Aldosteronoma is very small (all under 3cm), round or oval mass with homogeneous low density, but pheochromocytoma is relatively large mass (all beyond 3cm) with heterogeneous or isodense comparing to pancreaticdensity. Size and density of Cushing's adenoma has transitional character between aldosteronoma andpheochromocytoma. Overall diagnostic accuracy, sensitivity and specificity of CT in adrenal tumor/adrenal diseaseare 96.2%/87%. 96.4%/78.9% and 95.7%/97.7% respectively. The relative low sensitivity of adrenal disease(78.9%) isdue to inclusion of normal sized bilateral hyperplasia. Of 28 adrenal tumors, 27 were correctly diagnosed by CT,and there were one false positive and one false negative diagnosis. CT is a highly accurate non-invasive method inlocalization of adrenal tumors and differentiation of the tumors from hyperplasia.
