概括
多参数MRI有效检测2型糖尿病 (T2DM) 早期脏变化. 先进的成像技术,如intravoxel不连贯运动 (IVIM) 和血氧水平依赖 (BOLD) 的MRI,提供了对扩散和输液的定量见解.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 放射学 放射学是一门学科.
- 糖尿病学 糖尿病学
背景情况:
- 2型糖尿病 (T2DM) 是慢性病的主要原因.
- 在T2DM中早期发现脏变化对于及时干预和管理至关重要.
- 需要非侵入性定量成像生物标志物来评估早期糖尿病病.
研究的目的:
- 评估多参数MRI在确定T2DM患者早期脏变化的临床实用性.
- 评估intravoxel不连贯运动 (IVIM),血氧水平依赖 (BOLD) 和动脉旋转标记 (ASL) MRI参数的诊断性能.
主要方法:
- 一组41名T2DM患者 (正常蛋白尿和微蛋白尿) 和30名健康对照人接受了多参数MRI (IVIM,BOLD,ASL).
- 统计分析 (ANOVA,皮尔森相关性) 将MRI参数与估计的膜过率 (eGFR) 和专蛋白-肌素比率 (ACR) 进行了比较.
- 接收器操作特征 (ROC) 分析评估了个人和组合MRI参数的诊断性能.
主要成果:
- 在各组之间观察到皮质和髓扩散 (D,D*,f) 和 perfusion (RBF,R2*) 参数的显著差异.
- 皮层/髓层D,皮层f和RBF与eGFR正相关,与ACR负相关.
- 结合皮质IVIM衍生的D和ASL衍生的RBF,以及骨髓IVIM衍生的D和BOLD衍生的R2*,在检测早期脏变化方面表现出卓越的诊断性能.
结论:
- 多参数MRI (IVIM,BOLD,ASL) 能够对T2DM早期扩散,输液,氧化和血液流量的变化进行非侵入性,定量评估.
- 综合MRI参数,特别是皮质D/RBF和髓D/R2*,在评估与T2DM相关的早期脏变化方面表现出更高的疗效.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
