The Clinical Value of Contrast-Enhanced Ultrasound in the Differential Diagnosis of Peripheral Focal Lung Lesions
Objective:To explore the clinical value of contrast-enhanced ultrasound in the differential diagnosis of peripheral focal lung lesions.Methods:60 patients diagnosed with peripheral focal lung lesions through biopsy pathology and CT enhanced scanning who were admitted to our hospital from January 2022 to December 2023 were selected.All patients underwent contrast-enhanced ultrasound examination and the two groups were compared.Results:Among all patients,benign lesions accounted for 55.00%(33 cases)and malignant lesions accounted for 45.00%(27 cases)in the pathological examination results of biopsy.When analyzing the enhancement phase of benign and malignant lesions,it was found that there were certain differences.Early enhancement was predominant in benign lesions,up to 81.82%(27 cases),higher than 26.63%(8 cases)in malignant lesions(P<0.05),while late enhancement was predominant in malignant lesions,up to 66.67%(18 cases),higher than 12.12%(4 cases)in benign lesions(P<0.05).There were differences in imaging patterns between benign and malignant lesions.Benign lesions mainly exhibit dendritic enhancement,up to 63.64%(21 cases),which was higher than 14.81%(4 cases)in malignant lesions(P<0.05),while malignant lesions mainly exhibit centripetal enhancement,up to 62.69%(17 cases),which was higher than 3.30%(1 case)in benign lesions(P<0.05).There was no significant difference in enhancement phase and contrast mode between lung squamous cell carcinoma and lung adenocarcinoma in malignant lesions(P>0.05).The sensitivity to malignant lesions was 74.07%,and the accuracy of lesion diagnosis is 71.67%.It has a certain auxiliary diagnostic function.Conclusion:Contrast-enhanced ultrasound can distinguish benign and malignant peripheral pulmonary focal lesions based on the temporal characteristics and contrast mode of the lesions,and has certain application value in the differential diagnosis of peripheral pulmonary focal lesions.
