Figure 2From: Characterization of hepatic tumors using [11C]metomidate through positron emission tomography: comparison with [11C]acetate Time-activity curves of tumors. After injection of [11C]MTO (upper A panels) and [11C]ACE (lower B panels) expressed as tumor-to-liver ratio versus time after injection. Lines represent the mean value of individual experiments. Left panels represent hepatocellular carcinoma (HCC) and right panels focal nodular hyperplasia (FNH).Back to article page
