Abstract

Magnetic resonance imaging-proton density fat fraction (MRI-PDFF) is an emerging quantitative imaging biomarker that accurately measures the fat fraction of tissue by correcting factors influencing magnetic resonance signal intensity. Beyond fat quantification, it also measures R2* which is a direct measure of iron concentration. The utilization of MRI-PDFF in liver diseases is well established. In the present review, we focused on applications of MRI-PDFF in different body areas including pancreas, bone, muscle, spleen, testis, visceral, and subcutaneous adipose tissue. Future studies can enable tracking of quantitative fat fraction changes in different organs simultaneously, which can be critical in understanding fat metabolism.

质子密度脂肪分数:磁共振成像在肝脏以外的应用。
磁共振成像质子密度脂肪分数(MRI-PDFF)是一种新兴的定量成像生物标志物,通过校正影响磁共振信号强度的因素来准确测量组织的脂肪分数。除了脂肪量化,它还测量R2*,这是铁浓度的直接测量。MRI-PDFF在肝脏疾病中的应用已经得到了很好的证实。本文综述了MRI-PDFF在胰腺、骨骼、肌肉、脾脏、睾丸、内脏和皮下脂肪组织等不同身体部位的应用。未来的研究可以同时跟踪不同器官中脂肪含量的变化,这对理解脂肪代谢至关重要。
