Focal Lung Lesions
Conditions
Interventions
Gold Standard:The positive reference standard for biopsy results guided by two-dimensional ultrasound or contrast-enhanced ultrasound is malignancy
If it is benign, the subsequent puncture results, changes in the tumor in the CT report 6 months later, and the patients survival status are used as reference standards. If there are intraoperative/po
Index test:The method is a prospective randomized controlled trial, comparing the success rates of puncture diagnosis between the two groups. Use Sonoscape Marvo S80 Elite ultrasound diagnostic device
