Precision of diagnostic mammograms varies by radiologist For women with breast symptoms such as lumps, the ability of diagnostic mammograms to detect breast cancer accurately depends strongly which radiologist reads them, on December 11 in the Journal of the National Malignancy Institute according to an organization Health study published online. And it wouldn’t depend on which radiologist was reading the mammograms. The study group examined how well 123 radiologists interpreted nearly 36,000 diagnostic mammograms carried out to evaluate breast problems, such as lumps, from 1996 through 2003 at 72 U .S. Services, including six from Group Wellness, that contribute data to the Breasts Cancer tumor Surveillance Consortium. For different radiologists, sensitivity ranged from 27 % to 100 %; and false-positives, from 0 to 16 %.
