Method for improving magnetic resonance imaging of the breast
The present invention provides a fat saturation device to be used in conjunction with a magnetice resonance imaging (MRI) breast coil, which provides padding for the comfort of the patient being imaged while eliminating the skin-air interface, thereby reducing the level of artefacts in the image. The device comprises a coil surface pad that contacts the surface of the coil, the pad having apertures therein through which the patients breasts extend when the patient is positioned on the coil for imaging. Aperture sleeves that are removable or retractable extend from the bottom surface of the coil surface into the apertures of the breast coil. The device comprises a fat saturation material.
1. A device for enhancing magnetic resonance imaging of a breast, said device comprising:
a pad adapted for use in conjunction with a magnetic resonance imaging breast coil, said pad comprising a pair of apertures therethrough for receiving the breast and a flexible sleeve that extends downwardly from said pad, said sleeve being disposed in each of said apertures of the pad so that said sleeve extends into corresponding apertures of said magnetic resonance imaging breast coil, wherein said flexible sleeve is continuous with the pad so that the intersection of the pad and sleeve conforms snuggly to a portion of the breast near the chest wall and wherein said pad and sleeve comprise a fat saturation material.
2. The device of claim 1 , wherein said device comprises:
a plurality of releasably attachable components comprising a fat saturation material wherein when said components are attached to each other, said components define a pad comprising a pair of apertures for receiving the breasts to be imaged and a flexible sleeve that extends outwardly from said pad wherein a flexible sleeve is disposed in each of said apertures so that said sleeves are continuous with the pad so that the intersection of the pad and sleeve conforms snuggly to a portion of the breast near the chest wall.
3. The device of claim 1 , wherein said sleeve is movable.
4. The device of claim 1 , wherein said sleeve is removable.
5. The device of claim 1 , wherein said sleeve is retractable.
6. The device of claim 1 , wherein said sleeve is generally round in shape.
7. The device of claim 1 , wherein said sleeve is generally rectangular in shape.
8. The device of claim 1 wherein said fat saturation material is non-protonated.
9. The device of claim 1 wherein said fat saturation material is selected from the group consisting of perfluorochemicals, TEFLON®, amorphous thermoplastic polyetherimide resins, siloxane-polyetherimide, modified polyphenylene oxides and combinations thereof.
10. The device of claim 1 wherein said fat saturation enhancing material is selected from the group consisting of perfluorooctylbromide (PFOB), perfluorodecylbromide (PFDB), FC-77 and FC-43.
