Beta emission directly correlates with gamma emission in all tested tumor types in vivo (R = 0.8). Four tumor types were tested for gamma and beta emission following animal injection with radiolabeled 18F (n = 10 animals). Pancreatic, gastric, squamous cell and breast cancer cell lines injected subcutaneously into the murine model. Emissions were measured with portable probes on the tumor in vivo as well as on excised tumor ex vivo once tumors reached 1 cm in size. Beta and gamma emission directly correlated as determined by the Pearson correlation calculation of the R value.
