摘要：骨梗死临床发病率较低，多发生于长骨干骺端及骨干，骨梗死影像新技术报道也较为罕见。本文报道1例双下肢多发骨梗死MRI基于受限回波间距的快速梯度回波类CT成像及能谱CT钙抑制技术的影像表现，为临床提供诊断经验。

ABSTRACT：Bone infarction has a low incidence in clinical practice and mostly occurs in the metaphysis and diaphysis.Few studies report the advanced imaging technique for bone infarction.Here we reported the fast field echo resembling a CT using restricted echo-spacing and calcium-suppressed spectral CT imaging for a case of multifocal bone infarcts in both lower extremities，aiming to provide diagnostic experience for clinical practice.

Key words：bone infarction；fast field echo resembling a CT using restricted echo-spacing；CT-like MRI；spectral CT；calcium-suppressed technique

骨梗死是骨髓腔内的骨坏死，多发生于股骨远端及胫骨近端、远端，有多发性和对称性的特点［1］；目前，骨梗死的发病率尚不清楚，骨梗死临床表现无特异性，在临床工作中容易造成误诊［2-3］。（剩余4279字）
