HIF1A and neoplasm: The D* and f values were higher in the group with high expression of HIF-1α, because the expression of HIF-1α could induce the expression of VEGF and other genes (49), which increased tumor angiogenesis and local microcirculation perfusion, which was consistent with the results of previous studies on IVIM to evaluate the expression level of HIF-1α in cervical cancer (35).
