A recent study involving 459 lung cancer patients has demonstrated that low-dose photon-counting computed tomography (PCCT) enhances the identification of malignant features and boosts diagnostic confidence while significantly minimizing radiation and iodine exposure compared to energy-integrating detector computed tomography (EID CT). Using an ultrahigh-resolution protocol yielding 0.4 mm images, outcomes showed a 66% reduction in radiation dose and lower rates of adverse reactions, particularly in patients with smaller tumors. The findings underline PCCT's potential in clinical imaging applications.
