Contrast-Enhanced Ultrasound to Identify Treatment Response Following Transarterial Radioembolization in Patients with Hepatocellular Carcinoma

Trial Status: active

This phase II trial studies how well contrast-enhanced ultrasound (CEUS) with Lumason and Sonazoid works to identify treatment response following transarterial radioembolization (TARE) in patients with hepatocellular carcinoma (HCC). TARE is recommended for 15-25% of HCC patients. Treatment response is generally reviewed using computed tomography (CT) or magnetic resonance imaging (MRI). Identifying treatment response using CT or MRI can be challenging and identifying tumor survival is often delayed, which then delays needed re-treatment. Ultrasound imaging is a procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. CEUS is ultrasound imaging following the administration of a microbubble contrast agent, such as Lumason or Sonazoid. These contrast agents may enhance echo pattern differences between various tissues, which may enhance the visualization of images during the ultrasound. This may be a more effective way to identify treatment response following TARE in patients with HCC.
