Abstract：Quantitative susceptibility mapping (QSM) is a MR imaging technology based on the gradient echo se-quence. QSM reflects the difference of magnetic susceptibility between tissues by combining the magnetic map with the phase map. QSM can be quantitatively analyzed on susceptibility weighted imaging (SWI), and it has obvious advantages in detect-ing microvessels, mornitoring blood oxygen saturation, quantifying iron deposition, and identifying calcification and bleeding by measuring the susceptibility of tissues. QSM has been extensively applied in iron metabolism disease, intracranial hemor-rhage, brain tumors and cerebrovascular diseases, it has also been used in the study of abdomen, joints and cartilage, cardio-vascular and other systems. This paper introduces the principle and advantages of QSM and its clinical applications.
