1.To be able to distinguish the enhancement characteristics of benign and malignant focal liver lesions using microbubble-enhanced ultrasound techniques. 2.To be able to compare and contrast the characteristics to those seen on MRI and CT scans.3.To evaluate the benefits of using contrast enhanced ultrasound as an adjunct or instead of, CT/MR

The aim of the poster is to review the enhancement characteristics of microbubble-enhanced ultrasound scans of benign versus malignant liver lesions based on our experience of more than 500 studies. Examples of benign lesions such as haemangiomas, focal nodular hyperplasias, hepatic adenomas, abscesses and malignant lesions such as metastases and hepatocellular carcinomas will be illustrated with CT and MR correlation. A table enabling the reader to distinguish between the various lesions will also be formulated and the current best practice imaging modes, equipment and protocols using ultrasound contrast will be discussed. Finally, case examples of where microbubble enhanced ultrasound has been of greater diagnostic value compared with CT or MRI images will be illustrated.
