Mammography-comparison with previous mammograns helps

Importance of Comparison of Current and Prior Mammograms in Breast Cancer Screening
DOI: 10.1148/radiol.2421050684, Radiology 2007;242:70-77.

"Without prior mammograms, significantly more annotations were made. When only positive cases were considered, no difference was observed. Reading performance was significantly better when prior screening mammograms were available. At fixed lesion localized fraction, nonlesion localized fraction was reduced by 44% on average when prior mammograms were read. Comparison with prior mammograms significantly improves overall performance and can reduce referrals due to nonlesion locations. Limiting the availability of prior mammograms to cases selected by the reader reduces the beneficial effect of prior mammograms."
