There is no cure for the disease, with treatments designed to prolong the lives of patients. They are cancer cell-targeting molecules injected into the body that travel to tumor sites and release radiation that destroys the DNA of cancer cells. Radionuclides such as Pluvicto and Xofigo represent the most advanced treatments to date.
Chest CT is often used to diagnose and monitor lung function of adults with the condition but is not recommended for children because it exposes them to radiation and may require a contrast agent. The group conducted a study between April 2022 and April 2023 that included 54 children between the ages of 11 and 17.
Owing primarily to its noise reduction capabilities, DLR has repeatedly been shown to sharply lower radiation dose while maintaining image quality. In their review, Willemink et al noted that DLR yields improved image quality compared with FBP and HBIR, as well as the potential of between 30% and 71% lower radiation dose compared with HIR.
