title: Accuracy of computed tomography during arterial portography in the segmental localization of liver tumours.
abstract: The ability of computed tomography during arterial portography (CTAP) to identify and segmentally locate 20 hepatic tumours was prospectively assessed in 7 patients undergoing hepatic resection. All eight lesions greater than 2.5 cm in diameter were detected, but only two out of four and two out of eight of those measuring 1-2.4 cm and < 1 cm respectively. The overall segmental localization accuracy for detected lesions was 91%. Our results highlight the insensitivity of CTAP to hepatic lesions smaller than 1 cm in size, but have shown the accuracy of segmental localization for detected lesions.
