Abstract

To evaluate the accuracy of CT arterial portography (CTAP) of the liver, CTAP examinations from 111 patients were retrospectively reviewed and compared with the findings at laparotomy. Laparotomy had been performed within 3 weeks after the CTAP examination. In cases of resectable liver tumor, the result from the pathologic examination report was used to calculate the accuracy of CTAP. In cases of nonresectable liver tumor or liver without tumor, CTAP findings were compared with the result of a thorough inspection and palpation of the liver. the right liver lobe and the medial and lateral segments of the left lobe were separately evaluated. Thus, a total of 333 lobes/segments were evaluated. Tumor was found at laparotomy in 80 of 333... (More)

To evaluate the accuracy of CT arterial portography (CTAP) of the liver, CTAP examinations from 111 patients were retrospectively reviewed and compared with the findings at laparotomy. Laparotomy had been performed within 3 weeks after the CTAP examination. In cases of resectable liver tumor, the result from the pathologic examination report was used to calculate the accuracy of CTAP. In cases of nonresectable liver tumor or liver without tumor, CTAP findings were compared with the result of a thorough inspection and palpation of the liver. the right liver lobe and the medial and lateral segments of the left lobe were separately evaluated. Thus, a total of 333 lobes/segments were evaluated. Tumor was found at laparotomy in 80 of 333 lobes or segments. At CTAP a total of 94 lobes were evaluated as positive for tumor growth, 23 of these were falsely interpreted as positive and 9 were falsely interpreted as negative when compared with the findings at laparotomy. However, 3 patients called false-positives later turned out to be true-positives since the lesions were overlooked at operation. A sensitivity of 89% a specificity of 91% and an accuracy of 90% was calculated for CTAP. It is concluded that CTAP has a higher accuracy than other radiologic methods and should be considered suitable for preoperative evaluation of potentially resectable liver tumor.
