聚焦剪波弹性图 (fSWE) 显示出有前途的评估肝硬性在患有代谢功能障碍相关的脂肪性肝病 (MASLD) 和肥胖的患者. 这种新的技术表现出高精度和可靠性,有可能提高诊断能力.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 医疗成像医学成像
- 诊断技术 诊断技术
背景情况:
- 过渡性弹性图 (TE) 和2D剪波弹性图 (2DSWE) 在评估患有MASLD的肥胖患者的肝纤维化方面存在局限性.
- 肥胖和MASLD有助于使用当前弹性学方法进行不可靠的肝硬度测量 (LSM).
研究的目的:
- 评估针对MASLD患者的LSM聚焦剪波弹性图 (fSWE) 的可行性和性能.
- 在试点队列中,将fswe性能与TE和2DSWE等既定方法进行比较.
主要方法:
- 预计将招募26名成年MASLD患者.
- 在一次访问中使用FSWE,TE和2DSWE进行LSM.
- 对于19名受试者,可获得先前的纤维化分期数据 (活检或MRE).
主要成果:
- 在 15/26 的 fSWE,在 26/26 的 TE 和在 23/26 的 2DSWE 中成功获得了 LSM.
- 与2DSWE (AUC 0.74) 相比,fSWE与TE (92%) 的一致性很高,并且在晚期纤维化 (AUC 0.92) 中改善了诊断性能.
- 在肥胖患者 (BMI>35 kg/m2) 中,fSWE与TE的相关性达到了87%.
结论:
- 聚焦剪波弹性图 (fSWE) 是一种可行的技术,用于LSM在MASLD患者,包括那些肥胖.
- 与2DSWE相比,fSWE与TE具有很高的一致性,并且在晚期纤维化方面具有更高的诊断准确性.
- fSWE可能为查肥胖的MASLD患者提供一个有前途的替代方案.
