Quality Control in Magnetic Resonance Imaging


MSc of Medical Physics Iran University of Medical Sciences



MRI equipment has unique capabilities, such as human soft tissue and anatomical imaging, optimal resolution, and physiological and even functional imaging. But these desirable features must be fully assured in terms of the accuracy of the results, so the quality control of MRI equipment can be considered as a suitable solution, which is the same in practice. The help of this lecture is to provide basic information about the quality control process of MRI equipment and the goals of each of these processes.
Learning objectives:

Presentation of suitable quality control guidelines
Presentation of quality control standard phantoms 
Presentation of various quality control tests, including
Magnetic Field Homogeneity (MFH)
Magnetic Field Drift (MFD)
Signal to Noise Ratio (SNR)
Slice Thickness
Geometric Distortion
High Contrast Spatial Resolution
Low Contrast Object Detectability
Percent Signal Ghosting Ratio (PSG)
Percent Image Uniformity (PIU)
