Gallbladder emptying was evaluated in 15 adult celiac disease patients by oral cholecystography or ultrasonography, after fatty meal or cholecystokinin stimulation. Gallbladder inertia was found in 13 cases. Our study agrees with previously reported results; however it is the first one in which this abnormality was demonstrated by ultrasonography.

They certify that the presence of little hypoechogenic spicules at the periphery of a mass is strongly in relation with a parathyroid. They found in 17 patients signs of hypertrophic parathyroid; 8 of these had surgery with very good results for echotomography in 7 cases.

The investigation is conducted at 15 degrees and is adapted to the morphology of the femoropatellar space, with the assistance of a "Scout view". Patellar rolling is evaluated before and after quadriceps contraction during indifferent and external rotation.

The infant is placed in a block of expanded polystyrene, ensuring both restraint and maintenance of an isothermic regimen.

Ultrasonography findings are compared with those of intravenous urography, and in certain cases with those of arteriography. Ultrasonography appears to be indispensable in many cases in order to confirm intravenous urography results, to complement them, and possibly to make up for their deficiencies.

The radiological features of 47 villous tumors of the large bowel found in 39 patients by the double-contrast barium enema were studied. An attempt was made to determine the radiological indicators of malignancy and two features proved to be suspicious: large tumor size and indentation of tumoral base. This retrospective study emphasizes the advantages of the double-contrast technique in the detection of colonic villous tumors.

The authors describe the hepatic angiographic findings in two patients with primary miliary hepatic tuberculosis. The main angiographic features are abnormalities of the distal arterioles, with small, nodular and irregular formations. The hepatic and portal veins are normal.

The authors report their experience about 2,422 examinations with double contrast radiography in the study of the gastric posterior wall. This technique is of great value in the detection, analysis and follow-up of gastric ulcerations. In 54 per cent of cases, the double contrast radiography showed endoscopically proven ulcerations, which where not recognized by standard barium meal technique.
