False Positive Findings in CTAP (CT during arterial portography) using Spiral CT

ABSTRACT

PURPOSE: CTAP(CT during arterial portography) has been shown to be the most sensitive technique available for the detection of hepatic mass. But because of many false positive lesions, it is important to interpretate the findings correctly. So we tried to analyse the false positive findings in CTAP. MATERIALS AND METHODS: Materials were 47 patients that had (;TAP for the detection of hepatic lesions. After performing superior roesenteric artery (SMA) arterial portography for the detection of vascular variation, CT
