摘要
Objective Fascia is a rapidly decaying component under normal physiological state in magnetic resonance imaging, whose structure is membranous component in and between parenchymal tissue taking interstitial space. Imaging of fascia under normal condition has been left vaguely in the literature due to its signal void on conventional MR sequences because of its short T2* and thus has challenging demand in high image resolution and ultrashort time of acquisition. Methods The UTE is identified as short T2 imaging method of choice. Fascia can be directly imaged by changing sampling time and quantified by fitting the fascia T2* exponential decay curve. The gadolinium phantom with different ion concentration was scanned with multi-echo time UTE MRI and quantified T2* value. One healthy adult man was enrolled and scanned with the same modified sequence on the lower leg. Results MR images of phantom and fascia structure in human lower leg are performed with fine resolution and high contrast. According to the division of T2* value intervals, the fascia components of different structures can be distinguished. Conclusion The implementation of fascia quantitative MRI under normal condition has certain physiological physics meaning and can demonstrate feasibility of imaging of fascia with positive contrast.
