Utilizing MRI to Diagnose Breast Cancer
Magnetic resonance breast imaging (MRI) has been authorized by the U.S. Food and Drug Administration (FDA) since 1991 for use as a supplemental tool, besides mammography, to assist diagnose breast cancer. Breast MRI is an outstanding problem-solving technology. It is frequently utilized to examine breast concerns initial identified with mammography, physical exam, or other imaging exams.
According to Dutch researchers magnetic resonance imaging (MRI) could discover breast cancers that mammograms fail to notice in high-risk women. Their discovery, issued in the New England Journal of Medicine, lends support to the view that screening with both methods might be a better alternative for high-risk women than utilizing either one alone.
MRI is outstanding at imaging the increased breast as well, together with both the breast implant itself and the breast tissue nearby the implant (abnormalities or signs of breast cancer could at times be covered by the implant on a mammogram). MRI is so helpful for staging breast cancer, ascertaining the most suitable treatment and for patient follow-up following breast cancer treatment.
Breast MRI (magnetic resonance imaging) is an examination that might be employed to differentiate between benign (noncancerous) and malignant (cancerous) lesions. Doing this examination might decrease the number of breast biopsies done to assess a doubtful breast mass. Even though MRI could identify tumors in dense breast tissue, it couldn’t identify minute specks of calcium (recognized as microcalcifications), which represent half of the cancers identified by mammography.
The doctors tested 1,909 women who were at moderate or high risk for breast cancer, the largest sample ever in use for a survey of the efficiency of MRI scans. Every part of of the women had a clinical breast exam each six months, a yearly mammogram, in addition to a yearly MRI scan for four years. The examiners compared how well the MRI and mammogram identified malignant enlargements in the breast. MRI scans were much better at identifying breast cancer. The MRI bring into being 71 percent of breast cancer tumors in the sample, at the same time as mammograms detected simply 40 percent. Beyond the 45 whole cases of cancer detected, the MRI establish 22 that the mammogram missed, the mammogram bring into being 8 not observed by the MRI, and 10 were visible on both images. The other five were detected by means of clinical breast exams.
Other than its function as a diagnostic tool, researchers have been examining whether breast MRI might be practical in screening younger women at high risk of breast cancer. The majority women under 40 years of age do not need any breast imaging.
