Should the radiologist order an abdomen CT scan or an abdomen MRI? Abdominal disorders, including the alimentary tract and the genitourinary system, are usually diagnosed and addressed beginning with abdominal imaging. Diagnostic radiology, including ultrasound, computed tomography, MR imaging, and nuclear medicine, are all used in modern abdominal imaging as well. We bring you the latest news on key topics in abdominal imaging in these free articles and newsletters.
Time inevitably brings change. More than six and a half years after Radiology Daily began, this is the final post. Don’t worry! Launching next month will be a free, time-saving monthly e-newsletter, Oakstone’s new Highlights in Radiology. Here’s a taste of what you’ll get:
Insights from respected colleagues in the field of radiology and diagnostic imaging
Physician reviews of—and commentary on—radiology-related articles from … read more »
A health-insurance company’s “price transparency program” succeeded in driving insured patients to less-expensive MRI facilities and away from hospital-based facilities, according to an article in the current edition of Health Affairs.
The insurer was WellPoint. One of its subsidiaries commissioned the study, and another conducted it. The study looked at more than 100,000 members of WellPoint health plans from 2010 through 2012. … read more »
Studies are defining an ever-larger role for MRI in detecting prostate cancer. One of the most recent, performed by Australian researchers, found MRI to be 97 percent effective in ruling out prostate cancer for men with abnormal prostate specific antigen levels or digital rectal exam results.
Lead Investigator Phillip Stricker, MBBS, senior author of an article about the research in the … read more »
An algorithm developed at Mayo Clinic Children’s Center in Rochester, Minnesota, significantly reduces the use of CT scans for children with suspected appendicitis without affecting diagnostic accuracy, according to a study published online in Surgery.
The study looked at 331 emergency-department pediatric patients (18 or younger) who underwent appendectomies for suspected appendicitis. Of the patients, 41 percent were treated in the two years … read more »
A new technology that can create an “acoustic bottle” in midair could improve ultrasound imaging, according to researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory in Berkeley, California. The technique also shows promise in a number of more exotic fields, including acoustic cloaking, particle manipulation, and levitation.

The discovery by University of Wisconsin researchers of genes that are necessary for surviving high levels of radiation has potentially big implications for imaging and radiation therapy.
The researchers developed a highly radiation–resistant strain of Escherichia coli by exposing cultures of the bacterium to extreme doses of radiation. “We blasted the cultures until 99 percent of the bacteria were dead,” said Michael M. … read more »
A new type of nanoparticle actively seeks out cancer cells, then automatically assembles itself into clumps large enough to clearly show up on MRI scans.
Researchers at Imperial College London created the nanoparticle to increase both the sensitivity and specificity of MRI in detecting small, early-stage tumors. Nicholas J. Long, PhD, the Sir Edward Frankland BP Chair of Inorganic Chemistry, explained … read more »
Two new studies look at imaging-related lessons from the April 2013 terrorist bombing attack during the Boston Marathon—one of interest to post-traumatic stress disorder researchers, and the other of concern primarily to radiologists and the institutions where they practice.
The bombing presented an unanticipated opportunity for a group of researchers who had performed functional MRI brain scans on Boston-area teenagers for … read more »
Mayo Clinic and 10 other institutions from around the United States are leading an effort to institute a national protocol to limit radiation dosage when imaging children.
Representatives of the institutions published an invited commentary titled “An Appeal for Safe and Appropriate Imaging of Children” online last week in Journal of Patient Safety. Lead author Stephen J. Swensen, MD, a radiologist at … read more »
CT scans of two 40,000-year-old but nearly intact woolly mammoth mummies have given paleontologists a wealth of insights about the extinct elephant species to which they belong.
The frozen, mummified female carcasses were found in 2007 and 2008, 3,000 miles apart, in Siberia. They were just babies; “Khroma” was slightly less than two months old and “Lyuba” a month old when … read more »
