SR CEUS images of benign and malignant superficial LNs post 0.5 ml & 1.0 ml bolus injection of Sonovue. (A-B) In a malignant LN, a 1.0 ml bolus injection can delineate more microvessels than a 0.5 ml bolus injection. (C-D) In a benign LN, a 1.0 ml bolus injection didn’t not reveal significantly more microvessels compared with a 0.5 ml bolus injection
