Evaluating the efficacy of percutaneous puncture biopsy guided by contrast-enhanced ultrasound for peripheral pulmonary lesions

Figure 2 Receiver operating characteristic analysis of the diagnostic efficacy of puncture biopsy for lung carcinomas in different diameter angiography groups and the control group. A and B: Receiver operating characteristic (ROC), sensitivity, and specificity of the diagnostic efficacy of puncture biopsy in the control and contrast groups; C and D: ROC, sensitivity, and specificity of the diagnostic efficacy of puncture biopsy in the control and contrast groups for lesions 1-5 cm in diameter; E and F: ROC, sensitivity, and specificity of the diagnostic efficacy of puncture biopsy in the control and contrast groups for lesions with diameter ≥ 5 cm. AUC: Area under the curve.
