Science to Practice: Multiparametric Molecular and Functional US Imaging Goes Three-dimensional.

Area of Science:

• Oncology
• Medical Imaging
• Biomedical Engineering

Background:

• Microbubbles enhance diagnostic ultrasonography (US) but are not standard for clinical tumor diagnosis.
• Limitations of conventional US include poor reproducibility and limited sampling of entire tumors.
• Three-dimensional (3D) US offers a potential solution to these challenges.

Purpose of the Study:

• To evaluate the efficacy of 3D US with microbubbles for monitoring colon cancer xenografts.
• To assess the response to antiangiogenic therapy using functional and molecular US imaging.
• To compare 3D US findings with histologic results.

Main Methods:

• Application of a 3D matrix transducer for US examinations.
• Utilizing microbubbles for enhanced US imaging.
• Monitoring colon cancer xenografts during antiangiogenic therapy.
• Employing functional and molecular US imaging techniques.

Main Results:

• 3D US enabled early assessment of tumor response to antiangiogenic therapy.
• The imaging provided precise monitoring of therapeutic effects.
• Results showed high agreement between 3D US findings and histologic assessments.
• Functional and molecular imaging provided detailed insights into tumor response.

Conclusions:

• 3D US combined with microbubbles is a promising tool for evaluating tumor response to therapy.
• This approach overcomes limitations of conventional US, offering improved accuracy and reproducibility.
• The technique shows potential for early and precise assessment in clinical oncology.
