    Digital Mammography Screening with Photon-counting Technique: Can a High Diagnostic Performance Be Realized at Low Mean Glandular Dose?

    Digital mammography screening with dose-efficient photon counting enables desirable detection rates of small invasive cancers and ductal carcinoma in situ (DCIS), according to new research. Higher detection rates compared with statewide performance occurred with subsequent screening but at a higher recall rate.

    In a retrospective study of prospectively acquired data from the North Rhine–Westphalian mammography screening program (2009–2010), Stefanie Weigel, M.D., of University Hospital Muenster, Germany, and colleagues compared the screening performance of a direct radiography (DR) photon-counting scan system with those of statewide operating screening units using different digital technologies.

    Researchers examined 13,312 women with a DR photon-counting system and 993,822 women screened with either computed radiography (CR) or DR systems. The DR photon-counting scan system had a cancer detection rate of 0.76 percent for subsequent screening, compared with 0.59 percent for the other screening units, and a higher recall rate: 5.4 percent for the photon-counting method, 3.4 percent for the other methods. The DR photon-counting system demonstrated a higher detection rate of DCIS for subsequent screening compared to the statewide rate with CR and DR technology (0.23 percent vs. 0.12 percent), as well as for a subgroup of only DR technology (0.23 percent vs. 0.12 percent).

    “….Our study showed that digital mammography screening by using the dose-efficient photon-counting technique enables detection of small invasive cancers and DCIS above the desirable level of the European guidelines,” the authors write.

    April Public Information Outreach Activity Focus on ADHD

    In April, RSNA is distributing the “60-Second Checkup” audio program to nearly 100 radio stations across the U.S. The segments focus on the use of MR imaging to reveal low brain iron in attention deficit hyperactivity disorder (ADHD) patients.
