• Facilitate a deeper understanding of tumor biology and heterogeneity.
• Develop imaging biomarkers for patient outcomes using phenotypic and genotypic metrics.

Main Methods:

• Correlating imaging characteristics (imaging phenotype) with gene expression patterns and mutations.
• Utilizing high-throughput methods to extract and analyze multiple imaging parameters.
• Integrating genomic data with imaging findings to capture tumor biology.

Main Results:

• Radiogenomics aims to bridge the gap between imaging and genomic data in cancer research.
• The field holds promise for understanding tumor heterogeneity and biology.
• Initial results in various tumor types are encouraging.

Conclusions:

• Radiogenomics is a rapidly evolving field with significant potential in oncology.
