Tumor growth requires formation of new angiogenic vessels, which differ in their morphology from those of healthy tissue. These vascular abnormalities result in altered blood flow dynamics, which can be assessed by dynamic contrast-enhanced ultrasound (DCE-US). Two distinct approaches are typically employed in DCE-US following an intravenous injection of ultrasound contrast agent: assessment of perfusion...
Tumor growth requires angiogenesis and neovascularization, resulting in the formation of microvessels which differ in their morphology from those of healthy tissue. These vascular abnormalities result in altered blood flow dynamics, which can be assessed by dynamic contrast-enhanced ultrasound (DCE-US). Two distinct approaches are typically employed in DCE-US: the assessment of either perfusion or...
Higher microvascular density with tortuous and irregular vessels are hallmarks of cancer vasculature. These alterations can be captured by contrast ultrasound dispersion imaging (CUDI) and acoustic angiography (AA) at different scales: CUDI aims at obtaining an implicit measure of structural alteration by determining the dispersion kinetics of contrast agents. At a smaller scale, AA images the vascular...
