PACS data-mining technique tackles CR dose creep

By Brian Casey

Looking for a way to deal with dose creep resulting from your digital x-ray systems? If you have a PACS, the solution to the problem might be as close as your data archive, according to a group from the University of Washington in Seattle. They implemented a software application that mines data from their PACS archive to help monitor computed radiography (CR) radiation dose, cutting the dose nearly in half for some applications.

Researchers scrutinize CTA for pulmonary embolism

By Eric Barnes

More likely than not, a patient with unexplained shortness of breath or other symptom suggestive of pulmonary embolism (PE) will be sent for CT pulmonary angiography (CTPA) to rule it out. CT is fast and it does the job when vessels are examined systematically, but its false-positive rate can be high when combined with a low clinical probability of PE. Recent studies have shed new light on the use of CT in cases of suspected PE.

Cold case closed: CT solves iceman's cause of death

By Heather Hokenson

You could say it's the oldest open "cold case" to date -- the death of the famous Alpine glacier iceman. Since he was discovered in 1991, his 5,300-year-old mummified remains have been subjected to numerous scientific tests, and theories have abounded as to how he died. Recently, however, a team of Italian and Swiss researchers determined the iceman's exact cause of death using multidetector-row CT (MDCT).
