  "definitions": [
    "A radioactive substance being studied in positron emission tomography (PET) imaging to find certain types of cancer. Carbon C 11-choline gets taken up by cells in the body and more of it is taken up by cancer cells than by normal cells. A PET scanner is used to find which cells in the body have taken up carbon C 11-choline. Also called 11C-choline.",
    "A radiotracer consisting of choline labeled with the positron-emitting isotope carbon C 11 with potential imaging use. Upon administration, C-11 choline incorporates into tumor cells through an active, carrier-mediated transport mechanism for choline and then is phosphorylated intracellularly by choline kinase, an enzyme frequently upregulated in human tumors, yielding phosphoryl C-11 choline. In turn, phosphoryl C-11 choline is integrated into phospholipids in the cell membrane as part of phosphatidylcholine. As the proliferation of cancer cells is much higher than normal cells, tumor cells exhibit an increased rate of C-11 choline uptake and incorporation, allowing tumor imaging with positron emission tomography (PET)."
