Abstract
A tumor stroma imaging agent with a chemical structural formula (I): is provided, where R is hydrogen or fluorine. Compared with the prior art, the tumor stroma imaging agent exhibits significant affinity for fibroblast activation protein (FAP), high uptake for a malignant tumor with high FAP expression in a tumor stroma, and high sensitivity and specificity for the diagnosis of a malignant tumor, and is not prone to false positives. Therefore, the tumor stroma imaging agent can be effectively and safely used for the diagnosis and treatment of various malignant tumors with a prolonged half-life and an extended window period, which is conducive to clinical application.
