Although digital direct radiology (DR) is equivalent to screen film mammography (SFM) for breast screening among women aged 50-74 years, the cancer detection rate was lower for computed radiography (CR) in large concurrent cohorts in a recently published study.
Anna M. Chiarelli, Ph.D., of Cancer Care Ontario, Toronto, and colleagues examined concurrent cohorts of women 50-74 years of age screened with DR (220,520 patients), CR (64,210) or SFM (403,688) between 2008 and 2009 and followed the patients for 12 months. Performance was compared between cohorts, with SFM as the referent cohort. Associations were examined by using mixed-effect logistic regression.
DR detected 4.9 cancers per 1,000 mammograms, SFM detected cancer at a rate of 4.8 cancers per 1,000 mammograms and CR detected 3.4 cancers per 1,000 mammograms, results showed.
“Our findings are not consistent with those of earlier studies examining CR; however, our study is larger and compared concurrent cohorts,” the authors write. “This study suggests that screening programs offering both DR and CR should monitor the performance of each technology separately and may consider informing women of the potentially lower cancer detection rates with CR.”

The American Society of Neuroradiology (ASNR) recently launched a patient information website aimed at enhancing patients’ understanding of neuroradiology procedures and conditions. The site, ASNR.org/patientinfo, informs patients about what to expect during procedures, gives background on specific diseases and explains the neuroradiologist’s role in diagnosing and treating various conditions.
