The Development and Application of PET/CT Imaging in Lung Cancer Diagnosis: A Review

Lung cancer poses a considerable global health hurdle due to its elevated occurrence and fatality rates. Swift and precise identification of lung nodules hold vital importance in devising effective treatment plans. Routine diagnostic tools encompass X-ray CT and PET scans, supplying structural and metabolic insights, respectively. Nonetheless, depending solely on these techniques might not deliver exact diagnoses. As a result, the emergence of PET/CT systems has arisen, amalgamating PET and CT data. These systems furnish a comprehensive outlook on both metabolism and structure, enhancing the precision of lung cancer diagnosis, disease staging, and prognosis anticipation. The amalgamation of PET/CT technology demonstrates potential in clinical application. It assists in the premature spotting of lung cancer lesions, elevating patient survival rates, and guiding treatment methodologies. Furthermore, it curtails needless surgeries and radiation therapy, mitigating patient encumbrances and treatment hazards. In synopsis, the progression and adoption of PET/CT imaging in lung cancer detection bear immense significance. Therefore, this review briefly introduces the development and application of PET/CT imaging in lung cancer detection, which is of great significance for improving lung cancer treatment and diagnostic strategies and providing scientific evidence for its clinical practice.
