ABSTRACT
Objective To evaluate virtual navigation assisted contrast-enhanced ultrasound(VN-CEUS) by comparing VN-CEUS with routine CEUS in detecting focal liver lesion(FLL) invisible in B-mode ultrasound(BUS).Methods Forty-seven FLLs invisible in BUS were identified by CT/MR,and received VN-CEUS and routine CEUS respectively.Results The detection rate of VN-CEUS and routine CEUS were 78.7%(37/47) and 36.2%(17/47),the former was much higher than the later (P<0.01).In all the cases,fusion of CT/MR with ultrasound was achieved successfully and average time for image fusion was 5 min.compared with routine CEUS,VN-CEUS could more easily find FLLs shadowed by lung or ribs,FLLs in inhomogeneous liver background,and FLLs with brief or inapparent abnormal enhancement.ConclusionsVN-CEUS can greatly improve the detection rate of FLL that was invisible in BUS.
