[F-18]-FCH

[F-18]-Fluorocholine Injection (“[F-18]-FCH”), when used with positron emission tomography (PET), is being developed as a non-invasive imaging biomarker for the in vivo assessment of cellular proliferation and/or choline kinase upregulation. Clinical studies with a variety of cancer types suggest that [F-18]-FCH has potential as a tool for diagnosis, treatment planning, and tumour grading in cancers such as prostate cancer and hepatocellular carcinoma.

The uptake and metabolism of [F-18]-FCH closely mimics that of choline. Choline enters the cell using choline-specific transporters and is then predominately metabolised to phosphatidyl choline which is incorporated into the cell membrane. Since rapid cellular proliferation is a hallmark of cancer, there is an increased requirement for choline, reflected by upregulation of the choline metabolic pathway and/or choline transport; this results in increased choline uptake which is the basis for [F-18]-FCH PET imaging.
