MR Protocols Breast Imaging

Compared with 1.5T, 3T imaging has the inherent advantage of providing a higher signal-to-noise ratio (SNR) and higher resolution or faster scans, although there are trade-offs among these as well as certain limitations. 3T MR has a high specific absorption rate (four times that of 1.5T), decreased B1 homogeneity, longer T1 relaxation time, and increased susceptibility artifact. Despite these p...

MR imaging of the breast

Dynamic contrast enhanced (DCE)-MRI of the breast is currently the most accurate technique available for diagnosing and delineating the extent of in situ and invasive breast cancer, with studies consistently reporting sensitivities above 95%. It can identify disease which cannot be seen on mammography and ultrasound, is not affected by breast density and gives the best correlation with patholog...

Water/Fat Separation MR Improves Optical Breast Imaging MR Water/Fat Separation Improves Optical Breast Imaging

Background Optical imaging may be added to MR mammography to provide absolute concentration images of oxygenated and deoxygenated hemoglobin, water, and other endogenous and exogenous molecular agents. This is beneficial because hemoglobin and tissue oxygenation have been shown in several studies to have high specificity to breast cancer [1]. This combined optical/MR instrument has been shown t...

Comparison of MR imaging breast coils.

In one volunteer, five breast coils were evaluated for signal-to-noise ratio (SNR), uniformity, comfort, subject orientation, access to the breast, and unilateral imaging options. The four-coil arrays provided superior SNR, imaging flexibility, and access. Uniformity and comfort were issues with all coils. Substantial design differences exist between coils; purchasers should ensure that their s...

MR breast imaging guides interventional procedures

Rapid enhancement and early washout are generally observed in breast carcinomas, but there are exceptions to this pattern. Certain carcinomas, particularly lobular cancer and carcinoma in situ, may enhance slowly or not at all. On the other hand, some enhancement can be seen in benign lesions such as fibroadenomas. Because of its high sensitivity, MRI reveals small lesions that may not be visib...
