We sought to investigate the value of diffusion-weighted MR imaging in evaluating focal hepatic nodules in an experimental hepatocellular carcinoma (HCC) rat model.Forty rats with chemically induced primary hepatic nodules ranging pathologically from regenerative nodules (RNs) to dysplastic nodules (DNs) to HCC were examined with diffusion-weighted imaging. The apparent diffusion coefficient (ADC)...
500 keV and 900 keV Xe + , 400 keV Er + and 400 keV Tm + were implanted into potassium titanyl phosphate (KTiOPO 4 or KTP) at room temperature. The fluences were 1x10 16 ions/cm 2 , 1x10 15 ions/cm 2 and 2x10 15 ions/cm 2 , respectively, for Xe + , Er + and Tm + ions. In order to...
