Do you think stripping out textual identifying information in publicly available radiologic images will protect you against privacy violations? Think again. A paper presented Thursday at the 2010 RSNA meeting showed how facial images reconstructed from maxillofacial sinus and cerebral vasculature images could be matched in a database using commonly available face-matching software.
The dramatic growth of Medicare-related medical imaging utilization—which drew the attention of rate-cutting federal policymakers and the wrath of politicians on Capitol Hill in the mid-2000s—has ended, according to a study from Thomas Jefferson University in Philadelphia.
Cancer patients saw a four to five times greater increase in their average annual exposure to imaging-related ionizing radiation than the general population since 1994, according to a retrospective study of more than one million privately insured people in the U.S.
It should be possible to reduce radiation dose levels by as much as 50% in CT appendicitis scans without seriously sacrificing accuracy, a study presented Tuesday by Duke University researchers concluded.
A study presented Wednesday at the RSNA meeting adds further evidence to the recommendation women with newly diagnosed invasive lobular carcinoma should have their contralateral breast screened with MRI. Most women aren’t routinely screened in the contralateral breast because whether to do so is highly dependent on the surgeon’s preference. This research, however, provides more evidence why they should: MRI detected synchronous breast cancers in 16% of patients.
