As a first step towards the development of a neonatal cardiac MRI (CMRI) coil, we investigated the utilization, handling and image quality of a knee coil for CMRI in infants at 3 Tesla. Scout imaging and cine imaging with optimized pulse sequence parameters were performed in two neonates and the resulting images were evaluated for diagnostic purposes. All images were of high diagnostic quality. Complete examinations took less than five minutes. The excellent signal-to-noise ratio provided by this coil allowed all cine studies to be acquired with only three averages. In conclusion, a knee coil can be successfully applied in neonates for CMRI, but the coil design could be improved further to facilitate routine clinical use.
作为开发新生儿心脏磁共振成像（CMRI）线圈的第一步，我们研究了在 3T 场强下使用膝关节线圈进行新生儿 CMRI 的可操作性、处理方法和图像质量。对两名新生儿进行了优化脉冲序列参数的定位成像和电影成像，所得图像用于诊断目的。所有图像均具有较高的诊断质量。完整的检查时间不到五分钟。该线圈提供的优异信噪比允许仅使用三个平均次数完成所有电影研究。总之，膝关节线圈可成功应用于新生儿的 CMRI，但线圈设计可以进一步改进，以方便常规临床使用。
