- 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.
