Dear Digital X-Ray Insider,
In a new study on digital tomosynthesis, researchers from the Mayo Clinic in Rochester, MN, found that the technology offered better sensitivity than conventional chest radiography for detecting lung nodules, at a far lower radiation dose than CT.
In the prospective study of 82 patients, tomo found many more nodules than radiography, with a radiation dose just marginally higher than that of regular x-ray and some 37 times lower than CT.
The question is, so what? Tomo still fell well short of CT's sensitivity in the lung, meaning CT will continue to get the nod for most workhorse applications as well as emerging uses such as lung cancer screening. But tomo could find utility in areas where conventional radiography is being used. Find out what they are in this edition's Insider Exclusive.
In other news, a group of first-year radiology residents from the University of California, Los Angeles (UCLA) recently had a paper published in the Journal of the American College of Radiology on their analysis of image ordering protocols for patients with suspected pelvic trauma.
They found that a decades-old practice at UCLA of requiring portable pelvic radiographs for incoming trauma patients might not be necessary under certain circumstances. Find out what they are by clicking here.
