Quantitative susceptibility mapping (QSM) based on GRE phase data can provide an accurate measurement of the hemorrhage volumes by removing blooming artifacts inherent in traditional T2* weighted imaging. It is shown here that new developed STAR-QSM can effctively remove the streaking artifact and provide more reiable measure for hematoma volume and suceptibility quantification, e.g., for evaluating the patients per- and post-treatment. By taking the avantage of high quality susceptibility maps, susceptibility information can help to provide furhter classification of the hemorrhage stage.
