Sentence examples for tracer remains from inspiring English sources

The finding that the radioactive and fluorescent signal intensities overlap ex vivo (average R 0.91; Table  1) illustrates that the hybrid tracer remains stable throughout the entire process and largely remains trapped in the sentinel node.

While pre-therapeutic imaging with surrogate tracers remains the best and only means of adapting the therapeutic activity to be injected (such as 111In or 68 Ga for RAIT or 99mTc for SIRT), it could pose significant organizational issues depending on local constraints (especially for 111In pre-therapeutic studies) as well as additional costs.
