Diagnostic imaging is a function of diagnostic radiology concerned with or aiding in diagnosis using radiology. Diagnostic imaging helps radiologists to find the earliest stages of cancer, before the cancer has spread. Advanced diagnostic radiology includes MRI, CT, mammography, MRA, and ultrasound.
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.

Two new handheld optical imaging devices can detect and measure the extent of skin cancer tumors, particularly melanoma, say their developers.
One packs three different spectroscopic techniques—Raman spectroscopy, diffuse reflectance spectroscopy, and laser-induced fluorescence spectroscopy—into a single probe the size of a pen, connected to supporting equipment on a portable utility cart. In about four and a half seconds, it can … 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.

CT scans can guide not only the treatment of injured people but also the repair of damaged musical instruments, thanks to 3-D printers. Researchers at the University of Connecticut have been using CT to look deep inside antique instruments and even print replacement parts.
They got the idea from Robert S. Howe, MD, a gynecologist and reproductive endocrinologist in East Longmeadow, … read more »
A new, noninvasive technique combining photoacoustic imaging, a nanoscale contrast agent, and PET should provide much-improved functional imaging of the intestine, according to a paper published this month in Nature Nanotechnology.
Jonathan F. Lovell, PhD, senior author of the article, said tests of the new technique on mice look promising:
We could potentially induce a paradigm shift that allows for much more routine … read more »
The emerging field of radiomics—the extraction and analysis of “hidden” data from large amounts of medical images—could help doctors more accurately choose the precise radiation therapy doses necessary to kill tumors, according to a study presented today at the 56th Annual Meeting of the American Association of Physicists in Medicine in Austin, Texas.
Joseph O. Deasy, PhD, senior author of the … read more »
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 »
