The use of a specialized MR-compatible incubator (INC) is very poorly described in the literature and only with regard to brain imaging.
To present our own experience with brain and body magnetic resonance imaging (MRI) in the INC in a large cohort of neonates.
A total of 555 examinations were performed in 530 newborns with the use of a 1.5T system and Nomag IC 1.5 incubator, equipped with head and body coils.
More than half of neonates (54%) were prematurely born at 22 + 6-36 + 6 gestational weeks. They were examined from the first to 153 days of life (median: 18.5, mean: 37.7) with body weights 600-5000 g (mean: 3051 g), 23% of less than 2500 g. The proportion of brain MRIs to other body regions was 533:85 = 86%:14%. In 36.6% of cases, MRI showed more abnormalities than ultrasound (USG), in a further 21.8%, MRI diagnosis was completely different, in 4.7%, a pathology described on a USG was ruled out on MRI. The superiority of MRI over USG was 63.1%.
MR-compatible incubator significantly increased the availability of MRI to newborns, especially to premature and unstable newborns. The integration of body coils into the INC increased the spectrum of examinations and made possible the scanning not only of the brain but also the body. Dedicated neonatal coils improved image quality and allowed more accurate diagnosis than the previously used adult coils. Immobilization of the babies in the INC by means of Velcro belts and head fixation inserts is better than in adult coils. The closed space of the INC isolates newborns to a greater extent from the negative influence of noise in the MR environment.
在文献中，专门的磁共振兼容培养箱（INC）的使用描述得非常少，仅涉及脑成像。
在大型新生儿队列中介绍我们在 INC 中进行脑和身体磁共振成像（MRI）的经验。
在使用 1.5T 系统和配备头部和身体线圈的 Nomag IC 1.5 培养箱的情况下，对 530 名新生儿进行了总共 555 次检查。
超过一半的新生儿（54%）在 22+6-36+6 孕周时早产。他们从出生后第 1 天到 153 天（中位数：18.5，平均：37.7）进行检查，体重为 600-5000g（平均：3051g），23%的体重低于 2500g。脑 MRI 与其他身体部位的比例为 533:85=86%:14%。在 36.6%的病例中，MRI 显示的异常比超声（USG）多，在进一步的 21.8%的病例中，MRI 诊断完全不同，在 4.7%的病例中，MRI 排除了 USG 描述的病理学。MRI 比 USG 的优势为 63.1%。
磁共振兼容培养箱显著增加了 MRI 对新生儿的可用性，尤其是对早产儿和不稳定的新生儿。将体线圈集成到 INC 中增加了检查范围，并使不仅可以扫描脑，还可以扫描身体成为可能。专用新生儿线圈提高了图像质量，并比以前使用的成人线圈更能做出准确的诊断。用 Velcro 腰带和头部固定插件将婴儿固定在 INC 中比在成人线圈中更好。INC 的封闭空间使新生儿在更大程度上与 MRI 环境中的噪声的负面影响隔离。
