Breast MRI Jun 6th

Magnetic Resonance Imaging (MRI) - Breast

Magnetic resonance imaging (MRI) of the breast uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the structures within the breast. It is primarily used as a supplemental tool to breast screening with mammography or ultrasound. It may be used to screen women at high risk for breast cancer, evaluate the extent of cancer following diagnosis, or further evaluate abnormalities seen on mammography. Breast MRI does not use ionizing radiation, and it is the best method for determining whether silicone breast implants have ruptured.

6/6/16 - Findings:

There is mild background breast parenchymal enhancement. The breast composition is scattered fibroglandular elements. There is an approximately 7 mm x 8 mm x 7 mm, mildly irregularly marginated, heterogeneously enhancing mass, with mixed slow progressive, plateau and washout type internal enhancement kinetics, in the anterior depth of the parenchyma of the 6:00 to 7:00 radian of the left breast (e.g., series 8003, image 136), and with a HydroMARK biopsy marker abutting its superior margin; this is the known sonographically evident recently biopsied invasive breast carcinoma.

Also noted are multiple, sub‐1 cm in mean diameter, areas of clumped nonmass enhancement, with slow progressive type internal enhancement kinetics, scattered in the anterior depth of the parenchyma of the left breast from the 6 o'clock through the 10 o'clock radians (e.g., series 8003, images 568‐614), and which are likely sites of multifocal, and possibly even mildly multicentric, DCIS. This nonmass enhancement pattern partially corresponds to the recently biopsied malignant pleomorphic segmentally distributed left_ breast calcifications seen on mammography but also suggests that the mammographically evident calcified DCIS may slightly underestimate the extent of residual DCIS in the patient's breast.
