1.1 Contrast-enhanced ultrasound with SonoVue is recommended for characterising incidentally detected focal liver lesions in adults in whom an unenhanced ultrasound scan is inconclusive. An unenhanced ultrasound scan in which a focal liver lesion is detected, but not characterised, is defined as inconclusive.
1.2 Contrast-enhanced ultrasound with SonoVue is recommended for investigating potential liver metastases in adults:
-
if contrast-enhanced computed tomography (CT) is not clinically appropriate, is not accessible or is not acceptable to the person, and
-
in whom an unenhanced ultrasound scan is unsatisfactory and contrast is needed for further diagnosis.
1.3 Contrast-enhanced ultrasound with SonoVue is recommended for characterising focal liver lesions in adults whose cirrhosis is being monitored:
-
if contrast-enhanced magnetic resonance imaging (MRI) is not clinically appropriate, is not accessible or is not acceptable to the person, and
-
when unenhanced ultrasound scan is inconclusive.
