RESUMO
Infusion tomography of the gallbladder has proved to be more specific in the detection of pathologic disease as compared with conventional roentgenologic examinations by showing the wall of the organ instead of the contents. Infusion tomography of the gallbladder has been a useful initial procedure in patients with acute cholecystitis and in those with obstructive jaundice. It has helped to confirm diagnosis in patients with chronic lithiasic cholecystitis and nonvisualized gallbladder or with gallstones with documented on oral or intravenous studies. Infusion tomography of the gallbladder can be done on an emergency basis; it requires no prior preparation of the patient and usually yields an answer within 30 minutes. No significant complications have resulted from the high dose of iodized contrast material. There have been only two false results, one negative and one positive, so the procedure can be regarded as a highly reliable one.
