Hepatography by slow intravenous infusion of AG 60 99 Guerbet (iodized lipids in a stable emulsion) was performed in 31 patients, aged 17 to 77 years, to detect circumscribed hepatic lesions: metastases, cysts, and hepatic abscesses. The tolerance was good with minor side effects unrelated to the patient's age. The uptake of the medium involves the entire liver and lasts for several hours, allowing tomography to be carried out. Intrahepatic lesions with a diameter of less than one centimeter may be demonstrated. Hepatography proves to be the most accurate method available at present for exploration of the liver.
