Micro-calcifications (< 1 mm) are a fundamental marker of breast cancer by x-ray mammography, especially for the early diagnosis of ductal carcinoma in situ (DCIS). However with MRI, micro-calcifications are rarely detected using standard pulse sequences. The purpose of this study was to optimize MRI approaches for detecting micro-calcifications in the breast in comparison to mammography and conventional MRI. We achieved high spatial resolution and good visualization of micro-calcifications using a proton density weighted ultra-short TE MRI sequence with radial reconstruction. Ultra-short TE MRI has potential for detection of mammographically visualized micro-calcifications.
