Diagnostic accuracy of CT in circumscript liver disease

To evaluate the accuracy of CT in diagnosing circumscript liver disease, CT findings in 105 patients were compared to the results of invasive diagnostic procedures (laparoscopy, laparotomy, and autopsy). In all patients at least one of these procedures was performed in addition to CT. CT proved to be a valuable noninvasive method in detecting and differentiating circumscript liver lesions such us metastases, primary liver tumors, solitary cysts and polycystic disease, abscesses, and echinococciasis. The 10% rate of false positive and false negative diagnoses indicates the limitations of the method.
