Phase and R2* were calculated from multi\u2010echo 3D\u2010T2\u2010star\u2010weighted\u2010angiography data. MRI and CT data were coregistered using mutual information. Spearman's correlation was performed between quantitative phase and CT\u2010HU and R2* values. The Mann\u2013Whitney <jats:italic>U<\/jats:italic>\u2010test was used to see differences between CT\u2010HU and R2* values from corresponding positive and negative phase regions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>The median values of CT\u2010HU and R2* from regions with positive and negative phase were found to be 142.10 (range: 41.89\u2013491.75) and 68.5\/sec (range: 20\u2013110\/sec) and 137.30 (range: 30.83\u2013458.88) and 69\/sec (range: 0\u2013110\/sec), respectively. There was a significant correlation of positive phase values with corresponding CT\u2010HU and R2* values. In addition, there was a significant correlation of R2* and CT\u2010HU with negative phase values.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>We conclude that there is a significant correlation between negative and positive phase with CT\u2010HU and R2* values, suggesting that the CT hyperdense lesion may have both calcium and other minerals, which can be differentiated using phase imaging.
