Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/9973209 | https://www.ncbi.nlm.nih.gov/pubmed/8195884

PET imaging using 2-[11C]thymidine (dThd) was developed as a measure of tumor proliferation and cancer response to treatment. The drug was tested on patients with brain tumors. A PET image is a result of the metabolic processes for delivery, uptake, and retention in DNA by the tumor and degradative metabolism in the whole patient. 2-[11C]Thymidine is metabolized to [C11]CO2, which rapidly crosses the blood-brain barrier and distributes throughout the brain. 2-[11C]Thymidine itself is poorly transported by the blood-brain barrier, however, it may intercalate into DNA.
