摘要:
目的：比较自适应图像接收（AIR）线圈与传统乳腺专用线圈在乳腺磁共振（MR）成像中的应用，以期在保证图像质量的基础上提高受检者乳腺MR检查舒适度，为乳腺MR检查中线圈选择提供新方案。方法：对2023年1~3月在中山大学肿瘤防治中心行乳腺MR检查的34例健康女性受检者，分别采用两种射频线圈行乳腺MR检查。检查前后各发放调查问卷1份，收集受检者个人基本信息及检查舒适度情况；对比在两种线圈下T2WI fs和MUSE-DWI序列中的图像信噪比、表观弥散系数值，并由2名高年资医师对图像质量进行主观评价；分析舒适度及图像质量，比较两种线圈在乳腺MR检查中的优劣。结果：AIR线圈舒适度优于乳腺专用线圈，差异有统计学意义（P<0.05）；AIR线圈下T2WI fs、MUSE-DWI序列信噪比均高于乳腺专用线圈图像，差异有统计学意义（P<0.05），两组图像表观弥散系数值之间，差异无统计学意义（P>0.05）；AIR线圈下T2WI fs序列主观图像质量低于乳腺专用线圈图像，差异有统计学意义（P<0.05），MUSE-DWI序列两组图像主观评价差异无统计学意义（P>0.05）。结论：乳腺MR检查中，AIR线圈舒适度优于传统乳腺专用线圈，具有一定的临床应用及推广价值。
Abstract:
Abstract: Objective To compare the applications of adaptive image receiving (AIR) coil and traditional coil in breast magnetic resonance imaging (MRI) for improving the comfort level of breast MRI on the basis of ensuring image quality, and providing a new selection of radiofrequency coils in breast MRI. Methods A total of 34 healthy female subjects who underwent breast MRI in Sun Yat-Sen University Cancer Center from January to March 2023 were enrolled in the study, and two kinds of radiofrequency coils were used for breast MRI. Through questionnaire survey before and after examination, the personal information was collected, and the comfort during breast MRI was investigated. AIR coil and traditional coil were used for MRI using T2WI fat-suppressed sequence (T2WI fs) and multiplexed sensitivity encoding diffusion-weighted imaging (MUSE-DWI) sequence. The signal-to-noise ratio (SNR) and apparent diffusion coefficient (ADC) value of the obtained images were compared, and the image quality was evaluated subjectively by two senior physicians. The advantages and disadvantages of two kinds of radiofrequency coils in breast MRI were discussed through the statistical analysis on comfort level and image quality. Results The comfort level of AIR coil was superior to that of traditional breast coil (P<0.05). The SNR of both T2WI fs and MUSE-DWI sequences in AIR coil group was higher than that in traditional coil group (P<0.05), while there was no statistical difference in ADC values between two groups (P>0.05). In terms of subjective evaluation, the image quality of T2WI fs sequence in AIR coil group was lower than that in traditional coil group (P<0.05), while the difference in the subjective evaluation of MUSE-DWI sequence between two groups was trivial (P>0.05). Conclusion Compared with traditional coil, AIR coil for breast MRI has higher comfort level, worthy of popularization in clinic.
