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

Table 10

Comparison of time and time difference between contrast medium reaching lung lesions and adjacent lung tissues.

Contrast agent arrival time	Benign group	Malignant group
AT1			0.851	0.399
AT2			2.171	0.035
∆AT			4.734	<0.001
