Magnetic resonance imaging (MRI) of the lungs is challenging for several reasons, mainly due to the respiratory motion, low proton density, and rapid T2* decay. Recent MR sequences with ultrashort TE (UTE) coupled with respiratory compensation promise to overcome these obstacles. So far, there are very few studies on the relevance of these sequences in children. The aim of the study was to compare the diagnostic value of a respiratory-self-gated three-dimensional UTE sequence versus a conventional respiratory-triggered T2-weighted turbo spin echo (T2-TSE) sequence in a pediatric collective.

自由呼吸中使用 3D 超短 TE 的儿科 MR 肺部成像：我们是否已经超越了传统的 T2 序列？

肺部磁共振成像 (MRI) 具有挑战性的原因有几个，主要是由于呼吸运动、质子密度低和 T2* 快速衰减。最近具有超短 TE (UTE) 的 MR 序列加上呼吸补偿有望克服这些障碍。到目前为止，关于这些序列在儿童中的相关性的研究很少。该研究的目的是在儿科集体中比较呼吸自门控 3D UTE 序列与传统呼吸触发 T2 加权涡轮自旋回波 (T2-TSE) 序列的诊断价值。
