Low-Dose Computed Tomography (LDCT) is a medical imaging technique that uses lower levels of radiation compared to standard CT scans while maintaining image quality. LDCT is commonly used for lung cancer screening, particularly in high-risk populations such as long-term smokers. The reduced radiation exposure makes it a safer option for repeated imaging, facilitating early detection and monitoring of lung conditions. Studies have shown that LDCT screening can significantly reduce lung cancer mortality by identifying cancers at earlier, more treatable stages.
