Abstract
Objective: The present study aims to explore the dynamic impact of contrast-enhanced ultrasound (CEUS) on hepatic two-dimensional shear wave elastography (2D-SWE), especially in its assessment of liver fibrosis, and to analyze the pathological and biological basis of this impact.
Methods: From August 2023 to August 2024, 220 participants were prospectively enrolled, among which 111 underwent liver histopathological examination. The 2D-SWE examinations were conducted at the pre-CEUS phase, CEUS phase (5-6 min after the injection of SonoVue), early post-CEUS phase (8-10 min after the injection), and late post-CEUS phase (25-30 min after the injection), respectively. Analysis of variance compared the indexes across different phases. Multivariate linear regression analyses identified the factors influencing the difference in 2D-SWE measurement values (Emean) between pre-CEUS and CEUS phases.
Results: Emean at the CEUS phase and early post-CEUS phase was significantly lower than the pre-CEUS levels [the mean difference was 1.70 kPa and 0.90 kPa, respectively, both p < 0.001]. At the late post-CEUS phase, the Emean returned to the pre-CEUS levels (p = 0.078). Compared to the pre-CEUS phase, the percentage of the downgrade of significant fibrosis at the CEUS, early post-CEUS, and late post-CEUS phase was 55.3%, 35.3%, and 6.0%, respectively; while the downgrade of cirrhosis was 37.8%, 18.3%, and 2.4%, respectively. Liver inflammatory activity (p = 0.008, β = 0.88, 95% CI = 0.24-1.52) independently influenced the differences between the pre-CEUS and CEUS phase Emean. The higher the inflammatory activity grade, the greater the differences in Emean.
Conclusion: Following CEUS, 2D-SWE measurement values initially decrease and subsequently return to baseline levels. This transient decrease can lead to a downgraded assessment of liver fibrosis. Furthermore, the liver inflammatory activity is an independent factor influencing the magnitude of the reduction in 2D-SWE measurement values after CEUS.
期刊介绍:
Ultrasound in Medicine and Biology is the official journal of the World Federation for Ultrasound in Medicine and Biology. The journal publishes original contributions that demonstrate a novel application of an existing ultrasound technology in clinical diagnostic, interventional and therapeutic applications, new and improved clinical techniques, the physics, engineering and technology of ultrasound in medicine and biology, and the interactions between ultrasound and biological systems, including bioeffects. Papers that simply utilize standard diagnostic ultrasound as a measuring tool will be considered out of scope. Extended critical reviews of subjects of contemporary interest in the field are also published, in addition to occasional editorial articles, clinical and technical notes, book reviews, letters to the editor and a calendar of forthcoming meetings. It is the aim of the journal fully to meet the information and publication requirements of the clinicians, scientists, engineers and other professionals who constitute the biomedical ultrasonic community.
