Table 3

Detection of FLL not visible on conventional BMUS.

Characteristic	FLL lesions
	BMUS, (%)
Isoechoic	45 (45.4%)
Slightly hyperechoic	11 (46.8%)
Slightly hypoechoic	14 (7.8%)
Detected by first CEUS
Arterial hyperenhancement, (%)	45 (64.2%)
PVLP hypoenhancement, (%)	55 (78.5%)

FLL: focal liver lesion; BMUS: B mode ultrasound; CEUS: contrast enhanced ultrasound.
