Abstract

Background

Brain MRI in infants at ultra-high-field scanners might improve diagnostic quality, but safety should be evaluated first. In our previous study, we reported simulated specific absorption rates and acoustic noise data at 7 Tesla.

Methods

In this study, we included twenty infants between term-equivalent age and three months of age. The infants were scanned on a 7 Tesla MRI directly after their clinically indicated 3 Tesla brain MRI scan. Vital parameters, temperature, and comfort were monitored throughout the process. Brain temperature was estimated during the MRI scans using proton MR spectroscopy.

Results

We found no significant differences in vital parameters, temperature, and comfort during and after 7 Tesla MRI scans, compared to 3 Tesla MRI scans.

Conclusions

These data confirm our hypothesis that scanning infants at 7 Tesla MRI appears to be safe and we identified no additional risks from scanning at 3 Tesla MRI.

介绍婴儿超高场磁共振脑成像:关键参数，温度和舒适度

背景使用超高场扫描仪对婴儿进行脑MRI检查可能会提高诊断质量，但应首先评估安全性。在我们之前的研究中，我们报告了7 Tesla的模拟比吸收率和声学噪声数据。方法在本研究中，包括20名足月等效年龄至3个月大的婴儿。婴儿在进行临床指示的3特斯拉脑部MRI扫描后，直接进行7特斯拉MRI扫描。在整个过程中监测重要参数、温度和舒适度。在核磁共振扫描期间，使用质子核磁共振波谱来估计大脑温度。结果与3次特斯拉核磁共振扫描相比，在7次特斯拉磁共振扫描期间和之后，我们发现生命参数、温度和舒适度没有显著差异。结论这些数据证实了我们的假设，即用7特斯拉MRI扫描婴儿似乎是安全的，并且我们发现用3特斯拉MRI扫描没有额外的风险。
