| Résumé : | Recent advances in computed axial tomography (CAT) techniques encompass shorter scanning time and data processing systems of higher sophistication. The faster spatial resolution that may be presently achieved is of special interest for liver investigations. The effect of respiratory or intestinal movements may be minimized or even completely prevented. In addition, sequential examinations may be carried out with sufficient speed for detailed dynamic studies. Well circumscribed lesions as small as 0.5 cm in diameter may be currently detected with adequate techniques involving timely exploration after contrast administration. We performed a series of 1,650 liver examinations in two institutions with CAT-scanners of five successive generations. Inconclusive or false positive results that were encountered in up to 10% of our initial cases were rarely seen with most recent equipment. Our findings included cysts, polycystoses, hydatid cysts, hematomas, abscesses, focal nodular hyperplasias, adenomas, hepatic carcinomas and metastases. These diseases may be accurately characterized with modern CAT scans and additional experience will conceivably further refine etiologic diagnoses made with this procedure. |
