One alternative to mammography, Breast MRI or contrast enhanced magnetic resonance imaging (MRI), has shown substantial progress in the detection of breast cancer.In this method, the breast is scanned in an MRI device before and after the intravascular injection of a contrast agent (Gadolinium DTPA).

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. One alternative to mammography, Breast MRI or contrast enhanced magnetic resonance imaging (MRI), has shown substantial progress in the detection of breast cancer.In this method, the breast is scanned in an MRI device before and after the intravascular injection of a contrast agent (Gadolinium DTPA). The pre-contrast images are "subtracted" from the post-contrast images, and any areas that have increased blood flow are seen as bright spots on a dark background. Since breast cancers generally have an increased blood supply, the contrast agent causes these lesions to "light up" on the images.The available literature suggests that the sensitivity of contrast-enhanced breast MRI in detection of cancer is considerably higher than that of either radiographic mammography or ultrasound and is generally reported to be in excess of 95% (though not all reported studies have been as encouraging).
