After a decade of growth in teleradiology; now what's next?

December 14, 2010

It's been a bit more than a decade since teleradiology really started to take off in the U.S. Fed by a radiologist shortage in the early 2000s and a desire by many practices to shed their night call work.

Reconstructions of radiologic facial images could strip away patient privacy

December 03, 2010

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.

For cutting CT dose, start with the scout scan

December 02, 2010

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.

Big cuts in appendicitis CT scan dose possible, study suggests

December 02, 2010

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.
