Brief summary: The purpose of this study is to demonstrate the superiority of SonoVue®-enhanced ultrasound versus unenhanced ultrasound for characterization of Focal Liver Lesions using final diagnosis based on histology or combined imaging/clinical data as truth standard.

Detailed description: Unit of analysis for the outcome measures was the lesion, equivalent to the subject, since each subject had a single lesion that was to be characterized.

Eligibility criteria: Inclusion Criteria:

* Male/female.
* Provides written Informed Consent and is willing to comply with protocol requirements.
* Is at least 18 years of age.
* Has at least 1 focal liver lesion (FLL) (target lesion) requiring work-up for characterization. Target lesions may include those:
* Incidentally detected,
* In subjects with chronic hepatitis or liver cirrhosis,
* In subjects with known history of malignancy.
* Is scheduled for surgical removal or biopsy of the target lesion from 24 hours to 30 days after the SonoVue® administration OR
* In case tissue biopsy is not indicated nor surgery planned, is scheduled for or has performed a contrast-enhanced (CE) CT and/or CE-MRI of the target lesion from 30 days to 48 hours prior to or from 24 hours to 30 days after the administration of SonoVue®.

Exclusion Criteria:

* Has an acoustic window insufficient for adequate ultrasound examination of the liver.
* Has a FLL that cannot be identified with unenhanced ultrasound.
* Has received or is scheduled for antineoplastic chemotherapy or an invasive procedure in the time period between test procedures and truth standard assessments which may have modified the target lesion.
* Is receiving any other contrast medium, within the 48 hours before and up to 24 hours following the administration of SonoVue®.
* Has previously been enrolled in and completed this study.
* Known right to left cardiac shunt, bidirectional or transient.
* Has any known allergy to 1 or more of the ingredients of the investigational product (sulfur hexafluoride or to any components of SonoVue®).
* Has any contraindication to 1 of the planned imaging procedures (ultrasound, CT or MRI), e.g., implants, claustrophobia, inadequate medical conditions etc.
* Has received an investigational compound within 30 days before admission into this study.
* Has any medical condition or other circumstances which would significantly decrease the chances of obtaining reliable data, achieving study objectives, or completing the study and/or post-dose follow-up examinations.
* Is determined by the Investigator that the subject is clinically unsuitable for the study.
* Is a pregnant or lactating female. Exclude the possibility of pregnancy by:

  * testing on site at the institution serum beta-human chorionic gonadotropin (βHCG) within 24 hours prior to the start of SonoVue® administration,
  * surgical history (e.g., tubal ligation or hysterectomy),
  * post menopausal with a minimum 1 year without menses.
