Breast magnetic resonance imaging (MRI) has been repeatedly shown to have a high false-positive rate for additional findings in the breast resulting in additional breast imaging and biopsies. We hypothesize that breast MRI is also associated with a high rate of false-positive findings outside of ...
PEM displayed comparable performance to MRI, identifying 24 of the 25 invasive cancers (96%). Its false positive rate was only 16%, compared with 62% for MRI. Along with its strong sensitivity and low false-positive rate, PEM could potentially decrease downstream healthcare costs as this study...
The prognostic importance, and thus the clinical implications, of false-positive diagnoses made on the basis of breast MRI vs. radiographic screening differed significantly, with a reversed prevalence of high- and low-risk lesions. This should be taken into account when discussing the rate of ...
"The reduction of the false-positive recall rate is an important issue when considering the use of breast MRI as a screening tool," said study lead author Bianca M. den Dekker, M.D., from the University Medical Center Utrecht in Utrecht, the Netherlands. In the new study, Dr. den Dekke...
false positive biopsies for all ten radiologists (Supplementary Table6). In fact, breast US has come under criticism for having a high false positive rate13,14. As reported by multiple clinical studies, only 7-8% of breast biopsies performed under US guidance are found to yield cancers15,17...
She also took exception to the notion of high false-positive rates. “The positive predictive value for MRI in our study was higher than that of digital breast tomosynthesis in the screening situation,” said Dr. Kuhl. “A high positive predictive value and an interval cancer rate of...

Among these patients, twenty-five patients show false positive on breast MRI and ten patients show false negative. False positive lesions include intraductal papilloma (n=5), adenosis (n=3), fibrocystic changes (n=3), normal breast tissue (n=3), stromal fibrosis (n=2), fibroadenoma (n=...
In analyzing the research, Lauritzen offered this overview of findings and insights moving forward: “In summary, screening with the AI did considerably decrease the workload which was evident in the amount of reads in the recall rate and the false positive rate and positive predictive value, and...
"MRI is an excellentscreening toolfor breast cancer, but the higher rate of false-positive results keeps some women from undergoing the exam," said the study's co-author Martha B. Mainiero, M.D., director of the Anne C. Pappas Center forBreast Imagingat Rhode Island Hospital and associate...
