Correlation of ¹⁹F-MR signal intensity with tumor growth and PET parameters. (a) Tumor volume, (b) SUV, and (c) % ID/g measured on day 7 as functions of ¹⁹F-MR signal intensities measured on day 2. (d) Change in tumor growth from day 2 to day 7, (e) SUV_max measured on day 7, and (f) change in % ID/g from day 2 to day 7 as functions of ¹⁹F-MR signal intensities measured on day 2. ¹⁹F, fluorine-19; MR, magnetic resonance; PET, positron emission tomography; SUV, standardized uptake value; % ID/g, percentage injected dose per gram tissue; SUV_max, maximum SUV.
