Abstract

The aim of this study was to evaluate the efficacy of double arterial phase dynamic magnetic resonance imaging MRI with the sensitivity encoding technique SENSE dynamic MRI for detection of hypervascular hepatocellular carcinoma HCC in comparison with double arterial phase dynamic multidetectorrow helical computed tomography dynamic MDCTA total of 28 patients with 66 hypervascular HCCs underwent both double arterial SENSE dynamic MRI and dynamic MDCT The diagnosis of HCC was based on surgical resection n = 7 biopsy n = 10 or a combination of CT during arterial portography CTAP CT during hepatic arteriography CTA and/or the 6month followup CT n = 49 Based on alternativefree response receiving operating characteristic ROC analysis the diagnostic performance for detecting HCC was compared between double arterial phase SENSE dynamic MRI and double arterial phase dynamic MDCTThe mean sensitivity positive predictive value and mean Az values for hypervascular HCCs were 72 80 and 079 respectively for SENSE dynamic MRI and 66 92 and 078 respectively for dynamic MDCT The mean sensitivity for double arterial phase SENSE dynamic MRI was higher than that for double arterial phase dynamic MDCT but the difference was not statistically significant
