【摘要】：目的探讨MRI非对称回波三点法水脂分离-定量测定(IDEAL-IQ)技术对非酒精性脂肪肝病(NAFLD)定量诊断及分度的应用价值。方法将超声(US)检查诊断的68例NAFLD患者及50例对照者分别行3.0 T MRI IDEAL-IQ技术定量检查,测定肝脏脂肪含量,再将其分为轻度、中度、重度NAFLD组及对照组。分析US与IDEALIQ技术对NAFLD诊断及分度的一致性。结果 US诊断NAFLD患者68例(轻度36例、中度26例、重度6例),对照者50例;MRI IDEAL-IQ技术诊断NAFLD患者67例(轻度34例、中度30例、重度3例),对照者51例。二者对NAFLD的诊断及分度具有一致性(Kappa值=0.76,P0.05)。结论 MRI IDEAL-IQ技术对NAFLD的诊断及分度与US一致,能为NAFLD提供定量影像学指标。
[Abstract]:Objective to investigate the MRI asymmetric echo point method for determination of three water fat separation - quantitative (IDEAL-IQ) technology on nonalcoholic fatty liver disease (NAFLD) application value of the quantitative diagnosis and indexing. Methods ultrasound (US) examination in the diagnosis of 68 cases of NAFLD patients and 50 controls were 3 T MRI quantitative IDEAL-IQ Technology examination. The determination of liver fat content, can be divided into mild, moderate and severe NAFLD group and control group. The consistency analysis of US and IDEALIQ technology of NAFLD in diagnosing and grading. Results 68 cases of US NAFLD patients (36 mild cases, 26 moderate cases and 6 severe cases), 50 cases of control group; 67 cases of MRI IDEAL-IQ in the diagnosis of patients with NAFLD (34 mild cases, 30 moderate cases and 3 severe cases) and 51 controls. Two diagnosis and the degree of NAFLD is consistent (Kappa = =0.76, P0.05). Conclusion MRI IDEAL-IQ NAFLD on diagnosis and grading and US, can provide quantitative imaging means for NAFLD Standard.
