Low-Dose Computed Tomography (LDCT) is a medical imaging technique that uses lower levels of radiation compared to standard CT scans, making it safer for repeated use, particularly in lung cancer screening. It balances the need for diagnostic clarity with minimizing radiation exposure, thus reducing the risk of radiation-induced complications.

Medial imaging technique

Radiation exposure refers to the amount of ionizing radiation absorbed by an organism, which can originate from natural sources like cosmic rays or human-made sources such as medical imaging and nuclear power. Understanding and managing radiation exposure is crucial to minimize health risks, including cancer and genetic damage, by adhering to safety guidelines and regulatory limits.

Lung cancer screening involves the use of low-dose computed tomography (LDCT) to detect lung cancer at an early stage in high-risk individuals, primarily long-term smokers, which can significantly improve survival rates. It is crucial to balance the benefits of early detection with potential harms like false positives and overdiagnosis, making proper patient selection and follow-up essential.
