Quantitative Susceptibility Mapping for Differentiating Hydroxyapatite and Calcium Oxalate Breast Calcifications at 3T: A Phantom Study

A laboratory phantom study evaluates whether quantitative susceptibility mapping at 3-tesla MRI can distinguish hydroxyapatite from calcium oxalate breast calcifications. The article is posted on openRxiv.

Excisional biopsy of nonpalpable breast lesion identified by calcifications on mammogram. No basophilic calcifications were seen histologically. Calcium oxalate can be seen on routine light microscopy, but the crystals are nearly colorless and can easily be missed. With crossed polarizers, as used here, they really pop out. Be sure to look hard for calcium oxalate (usually in cysts or dilated ducts) before signing out a breast biopsy as "no calcifications seen," which would subject the patient t
