Early detection of liver nodular lesions is critical in improving patients survival rate. Previous studies have shown that for dynamic contrast-enhanced MR imaging of liver nodules, there exists correlation between nodules blood supplies and MR signal changes. In this retrospective study, haemal supplies correlation based strategy was introduced to identify the suspected hepatic nodules, including DN, RN and SHCC from dynamic contrast-enhanced MR Images, and the analysis results were in consistence with the clinical diagnosis under double-blind test. The proposed computer aided identification approach could be helpful to provide valuable information for the detection of hepatic nodules.
