Validation Study of the Velacur System in Comparison to MRE & MRI-PDFF in Patients With (Suspected) Liver Disease
Comparison of Steatosis and Fibrosis Measurements From Velacur and MRE/MRI-PDFF in Patients With Chronic Liver Disease
The goal of this open-label, non-randomized, prospective study is to compare Velacur and MRE in all sexes, 18-80 years old with Non-Alcoholic Fatty Liver Disease (NAFLD). The main aims is to:
- Validate the use of Velacur and elastography cut offs in a patient cohort with all types of chronic liver disease, against MRE results for fibrosis staging.
- Validate the use of Velacur and attenuation cut offs in a patient cohort with all types of chronic liver disease, against MRI-PDFF results for steatosis staging.
Participants will Study participants will attend 1 study visit, in which measurement of liver stiffness with Velacur and FibroScan, will be performed by a certified technician. As part of Visit 1, Patients will also complete an MRI exam which will include both MRE and MRI-PDFF measurements (MRI imaging can take place within 28 days of the Velacur scan).

Detailed Description
This will be a prospective, open label, validation study of the Velacur system in comparison to MRE and MRI-PDFF in patients with liver disease or suspected liver disease.
Approximately 100 subjects may be enrolled in this study. Participants should span all levels of fibrosis and steatosis.
The study is comprised of: Screening Period (up to 8 days) and Visit 1. There are no safety follow-up visits in this study.
The primary objective of the study is to compare the results of Velacur against MRE and MRI-PDFF results for liver stiffness and steatosis. As part of prior studies, using MRE as the gold standard, clinical cut-off for Velacur have been developed. The primary objective of this study is to validate these cut-offs to see if Velacur can correctly classify patients.
Secondary objectives include correlating the stiffness and attenuation results of Velacur with other clinical measures of fibrosis and steatosis such as Fib-4, and correlations with other clinical measurements collected through clinical care or clinical trials, such as Enhance Liver Fibrosis (ELF) test, FibroScan, MRI, or ultrasound based shear wave elastography (SWE) as they are available.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Elasticity measurements
Time Frame: 2024
|
Validate the use of Velacur and elastography cut offs with all types of chronic liver disease, against MRE results for fibrosis staging. The liver tissue elasticity is measured in kilopascals (kPa), using Velacur. The Velacur elasticity measurements will be compared to those from Magnetic Resonance Elastography, which is measuring liver tissue elasticity in kilopascals (kPa). |
2024
|
Attenuation measurement
Time Frame: 2024
|
Validate the use of Velacur and attenuation cut offs with all types of chronic liver disease, against MRI-PDFF results for steatosis staging. Ultrasound attenuation is a quantitative measurement of ultrasound image parameters. Attenuation is measured by Velacur, and uses units of of decibels per meter (dB/m). These numbers are compared to the fat percentage as measured by MRI proton density fat fraction, which is measured in percentage fat (%). |

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Serum markers such as Fib-4, APRI and NALFD Fibrosis score or ELF (enhanced liver fibrosis) score.
Time Frame: 2024
|
Comparison of Velacur stiffness and attenuation results with other clinical measures of fibrosis and steatosis, such as blood work, using readily available scores and attenuation results with other clinical measures of fibrosis and steatosis, such as blood work, using readily available scores.
