The Clinical Value of Low-Dose GE64 Slice Spiral CT Scan in the Differential Diagnosis of Benign and Malignant Pulmonary Solitary Nodules
Objective:To evaluate the effect and value of low-dose ge GE 64-slicespiral CT in the differential diagnosis of small solitary pulmonary nodules (SPNS). Methods:105 cases of solitary pulmonary nodules were included,all of whom underwent diagnosis and treatment at our hospital from April 2023 to May 2024. They were provided with low-dose 64-slice spiral CT scans,and the imaging characteristics,distribution,and dynamic enhanced CT scan results of benign and malignant solitary pulmonary nodules were described based on the final pathological results of the patients. Results:There were 53 cases of benign nodules and 52 cases of malignant nodules diagnosed by low-dose 64-slice spiral CT,the sensitivity,specificity and accuracy were 87.04％,90.20％ and 88.57％,respectively. The proportion of malignant nodular squamous cell carcinoma was the highest (46.30％),and that of Leiomyosarcoma carcinoma was the lowest (5.56％). The proportion of benign tuberculosis was the highest (35.29％),and that of hyaline hemangioma was the lowest (3.92％). The detection value of malignant solitary small pulmonary nodules on CT was significantly higher than that of benign pulmonary nodules (P<0.05). Conclusion:Low-dose GE 64-slice spiral CT is a sensitive,specific and accurate method for the diagnosis of benign and malignant small solitary pulmonary nodules.
