Exploration of CT Diagnostic Value and Imaging Characteristics of Early Peripheral Lung Cancer

This article attempted to analyze the diagnostic value and imaging features of CT (Computed Tomography) in early peripheral lung cancer. 80 randomly selected patients with early peripheral lung cancer admitted between September 2021 and September 2023 were selected as the research subjects for this experiment, and the selected patients were randomly divided into groups. 20 male patients and 20 female patients were assigned to the X-ray and CT groups, ensuring that multiple variables including age, symptoms, other medical history, and clinical data were as close as possible. After that, two methods were used to diagnose the patient, and the diagnostic accuracy of the two methods and the diagnostic accuracy of various imaging features were calculated. The diagnostic accuracy rate of the CT group was 92.50% (P<0.05), while the diagnostic accuracy rate of the X-ray group was 62.50% (P<0.05). In the comparison of diagnostic accuracy rates for spicule sign, tumor lobulation sign, vacuole sign, vascular bundle sign, and pleural indentation sign, the X-ray group was 57.50%, 72.50%, 52.50%, 80.00%, and 67.50%, respectively, while the CT group was 92.50%, 85.00%, 97.50%, 87.50%, and 90.00%, respectively. It can be seen that the performance of the CT group was also better than that of the X-ray group. CT examination is highly necessary in the clinical diagnosis of early peripheral lung cancer. Its diagnostic value and imaging feature analysis ability are excellent, and the diagnostic accuracy is high. Therefore, CT examination can play a significant role in the clinical treatment of early peripheral lung cancer and a series of similar diseases, and is worth promoting.
