摘要:
目的：探讨16通道婴幼儿颅脑专用线圈对0～6月龄婴儿颅脑MRI图像质量的影响。方法：选取32名0～6月龄患儿使用16通道婴幼儿颅脑专用线圈行颅脑MRI检查（专用线圈组），另选取同时期使用常规头颈联合线圈行颅脑MRI检查的32名0～6月龄患儿作为常规线圈组，扫描序列均包含横断位T1加权像（T1WI）、T2加权像（T2WI）、T2液体衰减反转恢复序列（FLAIR）以及横断位弥散加权像（DWI），分别对扫描图像进行主观和客观评价。结果：主观评分中：T1WI、T2WI、FLAIR序列评分均达到4分以上，DWI序列均达到3分以上；在T1WI、T2WI和FLAIR序列中两名评分者评分一致性程度较强（Kappa值分别为0.717、0.652、0.784），在DWI序列中，一致性程度一般（Kappa值为0.321），均具有统计学意义（P<0.05）。客观评价中，专用线圈组各序列的SNR和CNR在颅脑左右叶上均表现出高度的一致性，且颅脑左右叶SNR和CNR差异无统计学意义（P>0.05）；相较于常规线圈组，专用线圈组在各个序列SNR、CNR均有所增加，其中在T1WI序列SNR、CNR和DWI序列SNR，两组差异有统计学意义（P<0.05）。结论：使用颅脑专用线圈扫描0～6月龄婴儿颅脑图像可以满足临床需求；专用线圈组图像质量在主、客观评价中均优于常规线圈组。
Abstract:
Objective To investigate the effects of 16-channel dedicated craniocerebral coil on brain magnetic resonance imaging (MRI) image quality in infants aged 0-6 months. Methods Thirty-two infants aged 0-6 months receiving craniocerebral MRI examination with 16-channel dedicated craniocerebral coil were enrolled as observation group, while 32 infant aged 0-6 months receiving craniocerebral MRI examination with conventional head and neck combined coil in the same period were enrolled as control group. The scanning sequences included transverse T1 weighted imaging (T1WI), T2 weighted imaging (T2WI), T2 fluid-attenuated inversion recovery (FLAIR) and diffusion-weighted imaging (DWI) sequences. The scanned images were evaluated subjectively and objectively. Results In the subjective evaluation, T1WI, T2WI and FLAIR sequences scored higher than 4, and DWI sequence scored higher than 3. There were high consistency between two raters for T1WI, T2WI and FLAIR sequences (Kappa value=0.717, 0.652, and 0.784, respectively P<0.05), and moderate consistency for DWI sequence (Kappa value=0.321 P<0.05). In the objective evaluation, the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of each sequence in the dedicated coil group were highly consistent in the left and right lobes of the brain, and the differences in the SNR and CNR between the left and right lobes of the brain were trivial (P>0.05). The SNR and CNR of each sequence in the dedicated coil group increased as compared with the conventional coil group, and the differences in the SNR and CNR of T1WI sequence and the SNR of DWI sequence were statistically significant (P<0.05). Conclusion The brain images of infants aged 0-6 months obtained with a dedicated craniocerebral coil can better meet the clinical needs, and the image quality of the dedicated coil group is superior to that of the conventional coil group in both subjective and objective evaluations.
