Interventional radiology uses fluoroscopy, CT, and ultrasound to guide insertion through the skin by needle puncture, including wires and catheters, for procedures such as biopsies, draining fluids, and dilating narrowed vessels. Direct interventional radiology procedures include angiography, chemoembolization, thrombolysis, and varicous vein treatment.
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 »
MRI-guided high-intensity focused ultrasound noninvasively destroyed a benign bone tumor in the leg of a Canadian teenager. That night, for the first time in months, he was able to sleep without being jolted awake by excruciating pain.
The July 17 treatment by a team from The Hospital for Sick Children (SickKids) in Toronto was the North American debut of the procedure for … 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.

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 method of creating radioisotopes could not only eliminate the chronic shortages that the medical world has faced in recent years but also lead to new types of medical imaging and nuclear medicine therapy, according to one of the technique’s developers.
Mark Raizen, PhD, professor of physics at the University of Texas at Austin, is senior editor of an article … read more »
State regulation of radiologic technologists has “little impact on public health and safety” and should be abolished, according to a staff report of an agency of the Texas Legislature.
Christine Lung, vice president of government relations and public policy for the American Society of Radiologic Technologists, begs to differ:
Everyone knows that radiation is a carcinogen. If performed incorrectly, it’s a direct … read more »
An international team of researchers has found a way to make iron oxide nanoparticles behave usefully for both MRI imaging and treatment of tumors: encase them inside larger silicon and polymer particles.
That creates versatile iron oxide composites that can act as MRI contrast agents, be manipulated with magnets, be heated, and degrade quickly. Normally, you would need different sizes of … read more »
A breakthrough at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory in Berkeley, California, could lead to high-frequency ultrasound imaging with up to 1,000 times higher resolution than today’s medical ultrasounds.
Xiang Zhang, PhD, summed up the research this way:
We have demonstrated optical coherent manipulation and detection of the acoustic phonons in nanostructures that offer new possibilities in the development … read more »
