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.
