Hologic's Selenia digital mammography beats film, says study

A large-scale Norwegian study has found that Hologic's Selenia digital mammography system is better than screen film at detecting ductal carcinoma in situ (DCIS) - an extrememly early form of breast cancer.
The study, which compared the cancer detection rates of 18,239 and 324,763 women screened with digital and screen-film mammography, respectively, also found that Hologic's system gave a higher positive predictive value and lower technical recall rate than its analogue counterpart. However, there was no significant difference for invasive cancers, said the researchers, led by Einar Vigeland of the Vestfold Hospital in Tcentnsberg.
Hologic was encouraged by the news: "Until this study no researchers had looked at the performance of a specific digital mammography technology," said director of special projects Jim Culley. "The pixel size of the [Selenia] system is smaller, uses direct capture technology, and the image processing algorithms are unique, resulting in a sharp, high-contrast image".
The findings appear in an advanced online version of European Radiology (August 7).
