Correlation between chondroitin sulfate iron colloid-enhanced MR imaging and the histological grade of hepatocellular carcinoma.
The association between contrast enhancement by chondroitin sulfate iron colloid (CSIC) and the histological grade of hepatocellular carcinoma (HCC) was evaluated in 24 patients diagnosed by histological examination of surgical specimens (26 nodules: 11 well-differentiated and 15 poorly-moderately-differentiated nodules). In the well-differentiated HCC nodules, the tumor-liver contrast to noise ratio (CNR) was not significantly increased after i.v. CSIC injection on both T1-weighted and T2-weighted images. In the moderately-poorly-differentiated HCC, CNR was significantly increased after CSIC administration on both T1-weighted and T2-weighted images (p < 0.01). MR imaging using CSIC may be useful for diagnosing the degree of HCC differentiation.
