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.
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.
Study reveals breast pain can be only indicator of breast cancer. Findings challenge reluctance to image for breast pain alone.
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.
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.
CT scout or scanogram images make up only about 4% of the typical chest/abdominal scan radiation dose, but are an easy target for dose reductions, according to a study presented Wednesday. Further, as technology changes and protocol updates reduce overall dose rates, scout images will make up a relatively larger part of the total and still represent a good target for cuts.
Patients’ risk of developing cancer from CT scans is not as high as previously thought, but the rate still doubled over the time period studied, according to a study presented Wednesday at the RSNA meeting.
Too much visceral fat may increase a woman’s risk of developing osteoporosis, according to a study presented Tuesday at the annual meeting of the RSNA.
