摘要
目的:探索一种能有效抑制和消除颅脑MRI运动伪影产生的方法,以提高图像质量和工作效率。方法:利用包装CT管球的海绵,设计并制作了2 cm×7.5 cm×22 cm,3 cm×7.5 cm×22 cm,4 cm×7.5 cm×22 cm等3种规格的海绵垫,配合使用颅脑正交线圈进行颅脑MRI检查。结果:采用"加垫法"行颅脑MRI检查2 638例。其中,一次性扫描成功2 633例(占99.81%),失败5例(占0.19%);在扫描失败的5例患者中,第2次扫描时配合使用医用绷带成功4例,失败1例。结论:采用"加垫法"行常规颅脑MRI扫描,方法简单、可靠,可有效抑制和消除运动伪影的产生,提高图像质量和工作效率。
Objective To explore a method that restrain and dispel motion artifacts of MRI examination for better image quality and higher working efficiency. Methods The sponge package of CT tube was used to design and make sponge cushions in types of 2 cm×7.5 cm×22 cm,3 cm×7.5 cm×22 cm and 4 cm×7.5 cm×22 cm, which were used to MRI examination by quadrature coil of brain. Results The method of ＂adding cushion＂ was adopted to examine brain of MRI in 2 638 cases. Among them, 2 633 cases were successfully scanned, which accounts for 99.81%; 5 cases failed, accounts for 0.19%. For the failed cases, 4 cases were successfully scanned in the second time by using medical bandage in cooperation, while 1 case failed. Conclusion The method of ＂adding cushion＂ in routine MRI examination of brain can restrain and dispel motion artifacts, improving image quality and work efficiency. It is an easy, reliable, ideal method for restraining and dispelling motion artifacts in brain MRI examination.
