Carolina Freitas Lins et al.
Background: Six-point DIXON MRI provides fat fraction (FF) and R2* maps, enabling noninvasive assessment of bone marrow (BM) fat and iron-related changes. In sickle cell disease (SCD), chronic hemolysis and compensatory h...
Multimodal MRI reveals microstructural and macrostructural alterations in Parkinson's disease: A combined 3D structural and NODDI study [0.03%]
多模态MRI揭示帕金森病的微观结构和宏观结构变化：结合三维结构和NODDI的综合研究
Yuan Tian,Chengyu Li,Xinyu Song et al.
Yuan Tian et al.
Background: Parkinson's disease (PD)is a prevalent neurodegenerative disorder, and early diagnosis remains challenging due to the lack of sensitive and specific imaging biomarkers. Multimodal MRI provides a promising appr...

Magnetic Resonance Imaging (MRI) plays a crucial role in clinical diagnosis but suffers from a time-consuming data acquisition process. While under-sampling accelerates imaging, it inevitably introduces aliasing artifacts and detail loss. R...
Accuracy and homogeneity of dictionary-based T2-mapping dedicated to single slice and multi-slice multi-echo turbo-spin echo imaging [0.03%]
基于字典的T2图在单层和多层多回波涡旋自旋回波成像中的精度与均一性
Zilya Badrieva,Charles-Alexis de Mayenne,Thomas Troalen et al.
Zilya Badrieva et al.
Multi-echo turbo spin-echo (ME-TSE) sequences enable rapid T2 mapping but are prone to errors from stimulated echoes and slice cross-talk in multi-slice imaging. Moreover, the impact of different effective echo time (TEeff) selections on T2...
