Performance evaluation of domestically produced Shanghai chenguang mammary gland coil

目的:了解国产上海辰光乳腺线圈运行性能。方法:采用上海辰光乳腺线圈对55例女性患者行乳腺检查,对其MR图像的运动伪影、扫描范围、信噪比进行分析。结果:4例图像存在明显运动伪影,仅占9%;55例患者的Fov包括整个乳房及胸大肌,41例包括腋窝淋巴组织;53例患者的MR图像信噪比达1,占96%。结论:国产上海辰光乳腺线圈信噪比高,均匀性强,成像清晰;扫描范围大,可同时对乳腺、腋窝淋巴组织及胸大肌进行扫描成像。

Object： Understands mammary gland coil performance characteristic of the domestically produced Shanghai chunguang. Method： Inspect 55 example feminine patients by the Shanghai chunguang mammary gland coil, and analyse its MR movement false shade, FOV, the signal-to-noise ratio. Results： 4 examples have the obvious movement false shade, only accounting for 9%. 55 examples patient＇s Fov including the entire breast and chest muscle, 41 examples including armpit Lymphatic tissue; 55 example patient＇s MR image signal-to-noise ratio reaches 1, accounting for 96%. Conclusion： The domestically produced Shanghai chunguang mammary gland coil has the high signal-to-noise ratio, the cleared image quality, and the big FOV.
