To evaluate whether the histopathological differentiation and the expression of vascular endothelial growth factor (VEGF) of hepatocellular carcinoma (HCC) do show correlation with the apparent diffusion coefficient (ADC) value on diffusion-weighted imaging (DWI). ⋯ The histopathological differentiation of HCC shows inverse correlation with the ADC value. Therefore, DWI with ADC measurement may be a valuable tool for noninvasively predicting the differentiation of HCC.

To assess the dynamic activations of the key brain areas associated with the time-course of the sexual arousal evoked by visual sexual stimuli in healthy male subjects. ⋯ Our results illustrate the spatiotemporal activation patterns of the key brain regions across the three stages of visual sexual arousal.

To evaluate the clinical and radiological outcomes of transcatheter embolotherapy for treating sporadic pulmonary arteriovenous malformations (PAVMs) that were not associated with hereditary hemorrhagic telangiectasia. ⋯ Sporadic PAVMs are mostly the simple type with predominance in the lower lobe and peripheral locations. Transcatheter embolotherapy with coils or Amplatz vascular plugs is a safe and effective treatment for sporadic PAVMs and this provides excellent functional and radiological improvement.
