Original sentence: Despite the high sensitivity, MRI screening had a positive predictive value of 52%, which is totally accepted for cancer screening tests.However, two studies published in 2007 demonstrated the strengths of MRI-based screening:.In August 2007, an article published in The Lancet compared MRI breast cancer screening to conventional mammographic screening in 7,319 women.In March 2007, an article published in the New England Journal of Medicine demonstrated that in 3.1% of patients with breast cancer, whose contralateral breast was clinically and mammographically tumor-free, MRI could detect breast cancer.MRI screening was highly more sensitive (97% in the MRI group vs.Magnetic resonance imaging (MRI) has been shown to detect cancers not visible on mammograms, but has long been regarded to have disadvantages.Proposed indications for using MRI for screening include:
