This protocol is usually performed as a contrast study and might be acquired separately or combined with a CT chest or CT chest-abdomen-pelvis. On rare occasions, it will be performed as a non-contrast study. WebThese techniques include adjusting the radiation dose based on patient size and new software technology. A low-dose chest CT produces images of enough quality to detect many lung diseases and abnormalities using much less radiation than a conventional chest CT scan. In some cases, doctors may lower the dose by 65 percent or more.
