摘要: Longitudinal imaging techniques are needed that can meaningfully probe the tumor microenvironment and its spatial heterogeneity. Contrast-enhanced ultrasound, shear wave elastography quantitative ultrasound ultrasound-based provide information on vascular function micro-/macroscopic tissue structure. Modifications of induced by cytotoxic anti-angiogenic molecules in ectopic murine Lewis lung carcinoma tumors were monitored. The most heterogenous structures found treated with drug simultaneously accumulated highest levels necrosis fibrosis. group presented number correlations between parameters related to those micro-/macrostructure microenvironment. Results suggest how patterns multiparametric modifications be a more insightful marker changes occurring within during therapy.
