Quantitative Parameters of Contrast-Enhanced Ultrasound Combined with Lung Biopsy Were Used to Evaluate the Benign and Malignant Lesions around the Lungs

Abstract

In recent years, due to the influence of living habits and smoking, the number of lung cancer patients worldwide has increased year by year, and it has gradually developed into one of the common diseases endangering human life. CEUS can observe the lesion and realize the rapid identification of the location of the active area of the lesion. CEUS is the abbreviation of contrast-enhanced ultrasound technology. Contrast-enhanced ultrasound technology is to inject ultrasound contrast agent through a peripheral vein to perform ultrasound exploration to observe the enhancement of the internal nodules. Compared with color ultrasound, it can diagnose more accurately and improve the inspection effect. At present, this technology is used for the diagnosis of many types of space-occupying lesions, but it is rarely used for the diagnosis of lung lesions. The purpose of this study is to explore the role of CEUS quantitative parameters combined with lung biopsy in the assessment of benign and malignant peripheral lung diseases. Based on the relevant theoretical basis of CEUS and lung biopsy, 158 patients with peripheral lung disease were selected as experimental subjects, and they were divided into experimental group and control group for comparative experiments. Experiments proved the effectiveness of CEUS quantitative parameters combined with lung biopsy methods. The experimental results showed that, compared with the benign group, the time-intensity curve, the rise time, and the peak time of the malignant lesions were significantly prolonged. In addition, CEUS combined with the quantitative parameters of lung biopsy can effectively distinguish the activity of lung lesions and the site of necrosis and promote the effective increase of the positive rate of lung biopsy.
