Conclusions • Contrast Enhanced Ultrasound provides incremental diagnostic and prognostic information over standard clinical criteria and may be superior to competing techniques • Sono. Vue safety analysis of Bracco-sponsored clinical trials and 6 years of PMS suggests Sono. Vue falls in the low-risk category • Sono. Vue has excellent risk benefit profile 34 R.
