A Study to Test a New Fluid to Improve the Quality of Images Obtained by Using Sound Waves (Ultrasound) During Surgery

Ultrasound Imaging in Brain Tumour Surgery With the Use of SonoClear® System Mimicking Brain Tissue.

Source: ClinicalTrials.gov · Last updated 14 May 2026

Brief summary (registry, in English)

The objective of this clinical investigation is to assess the safety and performance of the SonoClear® System. Performance will be assessed by analysis of the contrast-to-noise ratio (CNR) and assessment of image quality by using the Surgeon Image Rating (SIR) Scale. This is a prospective, multi-centre single arm study where the performance of the SonoClear® System relative to routinely used acoustic coupling fluid is investigated by each patient being their own control. Patients with the diagnosis of high-grade glioma (HGG) and low-grade glioma (LGG) at up to 5 sites in Germany will be included. Additionally, safety data are collected at 72 hours, 30 days and 6 months post procedure.

  • Known Hypersensitivity to glycerol

Other

  • Immuno-incompetent patient (e.g., failing immune system due to AIDS)
  • Pregnant or lactating females or females who intend to become pregnant during the time of the study

Who the study is looking for
