A total of 35 patients having fifty two calcified cysts were imaged using conventional and T2 star weighted angiography, used for extracting phase images. A significant correlation between CT-Hounsfield values and phase values proves the sensitivity of phase imaging in detecting presence calcification in a lesion as that of CT. In addition its ability to differentiate between diamagnetic and paramagnetic minerals gives phase imaging an edge over CT in demonstrating these lesions.
