Recent fundamental research indicates that while SMI may not match the superiority and accuracy of vascular endothelial growth factor receptor 2 (VEGFR2)-targeted microbubble (MBVEGFR2)-based ultrasonography molecular imaging in cervical cancer microvascular imaging and angiogenesis monitoring, SMI remains a viable alternative when the use of ultrasonography contrast agents is contraindicated (36). This evidence concerns the gene KDR and cervical carcinoma.
