Radiogenomics bridges genomics and imaging to enhance precision medicine, particularly in oncology. It addresses tumor heterogeneity and predicts immune response and disease progression by linking genomic data with imaging phenotypes. This approach is cost-effective compared to traditional genetic sequencing and offers comprehensive insights into whole tumors rather than just biopsy samples. Radiogenomics facilitates tailored therapies by providing detailed genetic information across entire tumors, enhancing the ability to target complex, heterogeneous cancer manifestations. Moreover, it aids in distinguishing between benign and malignant lesions and stratifying patients by disease risk, thus improving diagnostic accuracy and screening processes. The integration of multi-omic data further strengthens the application of radiogenomics in diagnosis, treatment planning, and evaluation, pushing forward the development of quantitative and personalized medical solutions. Despite its potential, challenges remain in refining these techniques for broader clinical use, highlighting the need for continued innovation and research in the field.
