To demonstrate prediction of complications in osteoporotic vertebral fractures with magnetic resonance imaging (MRI) changes over time.
MRI signal intensities in osteoporotic vertebral fractures were investigated according to the interval between onset and imaging as follows: 0-10 days (early), 11-20 days (middle), and 21-30 days (later).
The diffuse low pattern rates were 52%, 84%, and 95% and 20%, 24%, and 52% in the early, middle, and later periods on T1-WI and T2-WI, respectively.
The diffuse low pattern increased with time. The MRI prediction of complications depends on the time phase.
通过磁共振成像(MRI)随时间的变化来证明对骨质疏松性椎体骨折并发症的预测。
根据发病与成像之间的时间间隔,对骨质疏松性椎体骨折的MRI信号强度进行如下研究:0至10天(早期)、11至20天(中期)和21至30天(后期)。
在T1加权成像(T1-WI)和T2加权成像(T2-WI)上,早期、中期和后期的弥漫性低信号模式率分别为52%、84%和95%以及20%、24%和52%。
弥漫性低信号模式随时间增加。MRI对并发症的预测取决于时间阶段。
