Theoretically, the APT-MRI signal depends primarily on the mobile amide proton concentration and amide proton exchange rates (which are related to tissue pH). The APT technique has been used for non-invasive pH imaging in stroke (where pH drops) and protein content imaging in tumor (where many proteins are overexpressed). Notably, it has been recently demonstrated in animal models that the APT-MRI signal is a unique imaging biomarker to distinguish between radiation necrosis and active tumor.

CLT1-(Gd-DTPA) specifically bound to tumor tissue and resulted in significant tumor contrast enhancement at a dose of 0.05 mmol/kg for at least 60 minutes after injection. In contrast, a non-targeted contrast agent, Gd(DTPA-BMA), cleared rapidly from the body with little tumor enhancement after 30 minutes post-injection at a dose of 0.1 mmol/kg. CLT1-(Gd-DTPA) had little non-specific binding in blood and normal tissues, including the liver and muscle, resulting in comparable non-specific enhancement in normal tissues as the control agent.
