Abstract
Objective To explore the clinical value of contrast-enhanced ultrasound (CEUS) and interventional therapy in the diagnosis of peripheral pulmonary lesions. Methods 68 patients with peripheral pulmonary disease admitted to our hospital from November 2017 to January 2019 were selected as experimental subjects. After the conventional ultrasound method was selected for the diagnosis of the lesions, the contrast-enhanced ultrasound method was selected for further examination of the lesions. In addition, percutaneous lung biopsy was conducted for different contrast-enhanced areas of the patients under the guidance of ultrasound, and the results were analyzed. Results The clinical lesions, after completion of ultrasonic imaging by the relative professional and experienced staff, through analysis of imaging results, should be completed with reasonable type of operation, there were 28 cases of type Ⅰ homogeneous enhancement, 36 cases of type Ⅱ uneven enhancement, 4 cases of type Ⅲ annular enhancement. Through the observation on the time to arrival, should be completed with reasonable type of operation, there were 12 cases of type Ⅰ 7-9 s, 48 cases of type Ⅱ 10-15 s, 8 cases of type Ⅲ >15 s. Ultrasound guided biopsy for peripheral lung lesions revealed 52 patients with malignant results, including 8 patients with squamous cell carcinoma, 28 patients with adenocarcinoma, 2 patients with lymphoma, 10 patients with small cell neuroendocrine carcinoma, and 4 patients with mesothelioma. Benign results were obtained in 16 patients, including 2 patients with inflammatory pseudotumor, 4 patients with inflammation, and 2 patients with atrophic lung tissue. Conclusions For patients with peripheral lung lesions, ultrasonic imaging and interventional diagnostic effect is exact; for high enhancement region showed by ultrasonography, reasonable ultrasound guided biopsy can significantly increase positive puncture rate, which provides certain clinical value for effective treatment and the improvement of rehabilitation state for patients with peripheral lung lesions.
