Advantages and disadvantages of magnetic resonance susceptibility effect applied clinically and countermeasures / 医疗卫生装备

Objective To explore the advantages and disadvantages of magnetic resonance susceptibility effect applied clinically and countermeasures. Methods The application range of susceptibility weighted imaging (SWI) technique and the harm of susceptibility artifact were introduced with considerations on MRI clinical application and experiences, and then some countermeasures were put forward accordingly. Results SWI technique could be used for the diagnoses of multi diseases, and susceptibility artifact could be suppressed by sequence, parameter and corresponding techniques. Conclusion Susceptibility effect contributes to extending the clinical application of MRI, and references are provided for the development and reform of other new techniques.
