Using in vivo highly sensitive surrogate biomarkers such as glucose phosphorylation based on ¹⁸F-Fluorodeoxyglucose, or cell proliferation based on¹⁸F-Fluorothymidine uptake, a wide array of biological data will be revealed without directly interfering with our primary biological process of interest. CROmed’s unique experience in radiomics adds the power of quantitative image heterogeneity and fractal dimension analysis to these data. Our CT and MRI images thus also contribute to functional studies.
