Quantitative susceptibility mapping (QSM) is a new technique for quantifying magnetic susceptibility. It has already found various applications in quantifying in vivo iron content, calcifications and changes in venous oxygen saturation. The accuracy of susceptibility mapping is dependent on several factors. ⋯ The uncertainties in estimating susceptibility differences using susceptibility maps, phase images, and T2* maps are analyzed and compared. Finally, example clinical applications are presented. We conclude that QSM holds great promise in quantifying iron and becoming a standard clinical tool.

To correlate the enhancement parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) with prognostic factors and immunohistochemical subtypes of breast cancer. ⋯ BPE, BEC and ipsilateral whole-breast vascularity, higher K(trans) and kep of the cancer and lower K(trans) and iAUC of ipsilateral breast parenchyma may serve as additional predictors of a poor breast cancer prognosis.

Can MRI related patient anxiety be prevented?
To evaluate the effectivity of a combined intervention of information and communication to reduce magnetic resonance imaging (MRI) anxiety using prolactin and cortisol as biochemical markers and State Trait Anxiety Inventory (STAI). ⋯ MRI anxiety can be reduced by information and communication. This combined method is shown to be effective and should be used during daily radiology routine.
