Journal ArticleDOI
Ultrasound Elastography: Review of Techniques and Clinical Applications
TL;DR: While ultrasound elastography has shown promising results for non-invasive assessment of liver fibrosis, new applications in breast, thyroid, prostate, kidney and lymph node imaging are emerging.
Journal ArticleDOI
Dose-dependent response of tumor vasculature to radiation therapy in combination with Sunitinib depicted by three-dimensional high-frequency power Doppler ultrasound
TL;DR: It is confirmed that tumor response to high doses of radiation is regulated by its vasculature, and that the response observed when radiation is combined with Sunitinib is linked to a vascular “normalization” effect.
Journal ArticleDOI
Quantitative ultrasound approaches for diagnosis and monitoring hepatic steatosis in nonalcoholic fatty liver disease.
TL;DR: Several different emerging quantitative ultrasound-based approaches used for detection and quantification of hepatic steatosis in patients at risk for nonalcoholic fatty liver disease are reviewed.
Journal ArticleDOI

TL;DR: Ultrasound driven microbubbles are demonstrated as a novel form of targeted antiangiogenic therapy in a breast cancer xenograft model that can potentiate additive effects to radiation in vivo.
Journal ArticleDOI
Quantitative Three-Dimensional Dynamic Contrast-Enhanced Ultrasound Imaging: First-In-Human Pilot Study in Patients with Liver Metastases.

TL;DR: 3D DCE-US imaging of liver metastases with a matrix array transducer is feasible and repeatable in the clinic and support 3D instead of 2D D CE US imaging to minimize sampling errors due to tumor heterogeneity.
