Summary
This study developed a noninvasive and real-time method to evaluate the distribution of programmed death-ligand 1 in the whole body, based on positron emission tomographic imaging of [68Ga] D-dodecapeptide antagonist. This technique has advantages over conventional immunohistochemistry and improves the efficiency of identifying appropriate patients who will benefit from immune checkpoint blockade therapy.
