receptor-α (ERα) and progesterone receptor (PR) are expressed generally in most individual breast cancers and so are important predictive elements for directing therapy. was performed using 18F-fluoroestradiol (18F-FES) for ER 18 furanyl norprogesterone (18F-FFNP) for PR Limonin and 18F-FDG for blood sugar uptake. Tracer Limonin uptake within the tumor was quantified and weighed against receptor… Continue reading receptor-α (ERα) and progesterone receptor (PR) are expressed generally in most
