Aug. 12, 2025 —Sonic Incytes Medical Corp, has announced that the U.S. Food and Drug Administration (FDA) has granted 510(k) clearance for Velacur ONE, its point-of-care ultrasound elastography device. Building on the success of its original model, Velacur, Velacur ONE introduces an enhanced interface and features for improved portability and user experience. These improvements enable broader scalability to support Sonic Incytes’ accelerated US and global expansion strategy. Velacur ONE measures attenuation, VDFF (Velacur Determined-Fat Fraction), and liver stiffness using 3D S-WAVE and aids in the management of chronic liver disease including MASH and MASLD.
Velacur ONE arrives at a critical time for improved non-invasive testing, following the recent FDA clearance of Rezdiffra — the first therapeutic for Metabolic dysfunction–associated steatohepatitis (MASH), a progressive and often underdiagnosed liver disease. In the U.S. alone, an estimated 100 million adults have Metabolic dysfunction–associated Steatotic Liver Disease (MASLD)1, with 15–20 million of those affected by MASH2. Yet, 90% of MASH cases remain undiagnosed3. If left untreated, worsening MASH increases morbidity and may progress to severe complications, including cirrhosis, liver failure, liver cancer, and liver transplant4,5. MASH remains challenging to diagnose effectively due to the limitations of existing non-invasive methods, especially those available at the point-of-care.
With the first therapeutic now available and more in the pipeline, clinicians need improved non-invasive tests to diagnose and monitor MASH at point-of-care6. Current treatment guidelines for MASH recommend imaging-based elastography, such as Velacur™, to assess liver scarring (fibrosis) and fat content (steatosis). While ultrasound elastography is widely used, when it comes to treating patients with MASH, liver stiffness alone cannot be relied on to assess treatment response in the short term7. The best predictor of treatment responses was a decrease in steatosis (identified as ≥30% reduction in MRI-PDFF)8.
VDFF, Sonic Incytes’ proprietary algorithm that received FDA clearance in 2024, demonstrates a strong correlation (r = 0.85) with MRI-PDFF—the gold standard for liver fat measurement—and achieves an outstanding accuracy (AUC) of 95% of patients with more than 5% MRI-PDFF, defining the presence of hepatic steatosis9. Velacur ONE™ combines this technology with a refined user interface, including B-mode imaging—enabling 3–4x higher reimbursement than non-imaging elastography—and an AI-based organ overlay feature to aid in liver localization, making it the only point-of-care device that estimates both liver stiffness and attenuation that correlates to MRI-PDFF.
