Vasculogenic mimicry (VM) refers to tumor cells mimicking endothelial cells and directly participating in blood vessel formation, which appears in 2 distinctive forms, namely, the tubular type and the patterned matrix type. In liver cancer, VM is associated with tumor aggressiveness and poor clinical outcome. DENA-induced primary liver cancer model in rat appears an optimal VM model with both the 2 VM types. DWI and DCE-MRI were used to characterize and distinguish different VM types, and sensitively predicting diverse therapeutic responses to a vascular-disrupting agent CA4P.
