Abstract：Quantitative susceptibility mapping(QSM),as an emerging magnetic resonance imaging(MRI)technique,has the function of quantifying magnetic susceptibility.Currently,it is mainly applied in the diagnosis of central nervous system de-generative diseases,classification of intracranial tumors,and differentiation of calcification and hemorrhage,and etc.With the advancement of technologies,such as water-fat separation and compensation for cardiac and motion artifacts,the deficiencies of QSM in imaging outside the head have been gradually overcome,and its application scope in cardiovascular diseases,digestive system diseases,and urogenital system diseases has been continuously expanded.QSM offers the distinct advantage of providing susceptibility information directly linked to tissue pathophysiology,enabling true quantitative measurement of magnetic suscepti-bility.By integrating with radiomics,QSM has played a pivotal role in disease subtyping and predicting clinical outcomes.This synergy holds significant promise to become a powerful instrument for guiding personalized clinical therapy.
