Abstract

To assess the correlation between magnetic resonance (MR) imaging findings and angiogenetic activity in hepatocellular nodules evaluated by immunohistochemical staining with antibody of vascular endothelial growth factor (VEGF). We searched the pathologic records of our institution from December 1999 to April 2002, and included 16 patients with hepatocellular carcinoma (N = 14), large regenerative nodule (N = 1), and dysplastic nodule (N = 1) who underwent orthotopic liver transplantation (10 patients) or partial hepatectomy (six patients) and MR imaging within an interval of two weeks. The MR images were retrospectively assessed qualitatively and quantitatively. Angiogenetic activity of the hepatic nodules was evaluated by means of immunohistochemical study for VEGF. Analysis of variance and the Scheffé criterion were used for statistical evaluation. Hepatic nodules with moderate to strong immunoreactivity for VEGF showed higher signal intensity on T1-weighted images (P < 0.05) and those with intense immunoreactivity for VEGF showed higher signal intensity on T2-weighted images (P < 0.05). No correlation was found between the immunoreactivity for VEGF and tumor vascularity on postcontrast early- and late-phase images. Our curr...Continue Reading
