Using MRI to detection and assessment of breast cancer, agent of gadolinium contrast is used to highlight lesions and their extent. For minimize loss of visibility using subtraction and fat suppression techniques.

Screening MRI is not practical for general use, that because high cost and limited availability. Mammographic screening is cheaper than MRI screening, but the study said MRI might be the most cost efficient screening modality, especially for a high-risk probability of breast cancer.
Especially for breast coils the MRI breast imaging maybe the best choice, cause bilateral multichannel system. The MRI system can scan the whole body with magnet of 1.0 T or more. Here MRI Scanners feature, slice thickness of 2.5 mm or less and a plain resolution of 1.3 mm or less, and the latest high end is 1.5 T scanners can achieve a Voxel size of 2 mm or less.
MRI sensitivity for breast lesions is no doubt, but the specificity is not adequate. MRI-guided biopsies is often used or performed for histological examinations. This two different MRI guided intervention methods usually for used:
Here several biopsy devices on the market: coaxial core needle system, stereotactic system, biopsy guidance device and vacuum assisted core biopsy gun. Above type of devices have greater versatility in radiology department. But if breast coils are not available, then standard whole body scanners can be used to breast MRI imaging.
Now, a dedicated machine is available, the different is that machine can custom-designed for breast MRI, and the patient must be pleased. And the scanners will be focus on specialized task needed on particular group of patient.
This is the reason why an MRI scanner is more expensive: Standard 1.5 T multi-purpose MRI scanners cost between 1.1 - 1.9 million dollars. Dedicated breast MRI scanners costs 1.4 - 1.8 million dollars. All MRI scanners require investment in terms of physical space, running costs, maintenance and staffing. A dedicated breast scanner will require some more costs.
