A Simple Method for Dispelling Motion Artifacts in MRI Examination of Brain / 医疗卫生装备

ABSTRACT

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.
