Cardiovascular, or cardiac imaging, is increasingly popular as a diagnostic aid. Cardiac cat scan, MR, and PET in cardiac diagnosis are increasingly relevant modalities in the cardiology and nuclear medicine communities. This trend is leading to a critical demand for MRI cardiac imaging and cardiac scan imaging services.
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 »
Here are three headlines from medical websites:
“Lifetime cancer risks from X-rays for children ‘relatively low'”
“Imaging Hikes Ca Risk in Kids With Heart Disease”
“Kids with complex heart disease at higher risk of imaging-induced cancer”
Each headline (from, respectively, Medical News Today, MedPage Today, and Health Imaging) refers to the same study, conducted by researchers at Duke University. Circulation published an article about it online on … read more »
University of Michigan researchers may finally have figured out how to use terahertz rays for imaging—by converting them into ultrasound.
The terahertz band lies between microwaves and infrared light on the electromagnetic spectrum. (From left to right, longer to shorter wavelengths, the spectrum is radio waves, microwaves, terahertz waves, infrared waves, visible light waves, ultraviolet waves, X-rays, and gamma rays.) We’ve … read more »
If everything goes right, a new radioisotope plant will open in Columbia, Missouri, right about the time North America’s major source of radioisotopes is scheduled to shut down for good.
Last week, Northwest Medical Isotopes of Corvallis, Oregon, announced plans to open a $50 million facility to produce molybdenum-99 at the University of Missouri’s Discovery Ridge Research Park in Columbia. That … read more »
Two radiotracers commonly used in lung scans have received huge price increases—in one case, a hike of more than 2,000 percent.
Jubilant DraxImage of Montreal, Canada, has increased the prices of macroaggregated albumin (MAA) and diethylenetriamine pentaacetate (DTPA). Both are used for ventilation/perfusion (V/Q) lung scans, which are most often performed in cases of suspected pulmonary embolism.
Mark Tulchinsky, MD, of Penn … read more »
Pattern-recognition computer software analysis of CT brain scans may help flag ischemic stroke patients who should not be given clot-busting drugs, according to a new study. But the technology needs a lot of work before it’s ready for clinical use. For one thing, it takes about a half hour to process each scan.
An article about the study was published online … read more »
Radiologists’ yearly income decreased by 2 percent in 2013, to an average of $340,000, according to Medscape’s annual physician compensation survey.
Radiologists still enjoyed the fifth-highest income among specialists, behind orthopedists ($413,000), cardiologists ($351,000), urologists ($348,000), and gastroenterologists ($348,000). They ranked slightly lower—seventh—among specialists in feeling fairly compensated. Only 53 percent of radiologists said their compensation was fair, putting them behind … read more »
Up to one third of U.S. CT scanners will have to be replaced by 2016 in order to avoid a 5 percent Medicare penalty, the Medical Imaging & Technology Alliance (MITA) estimates.
That’s because of a provision included in the Protecting Access to Medicare Act of 2014—the so-called “doc fix” bill that prevented a 24 percent Medicare pay cut for doctors. … read more »
Google Glass—or just “Glass,” as Google calls it—is starting to become a mainstream health care tool. Earlier this year, for example, Indiana surgeons used it to pull up MRI and X-ray images of a patient during surgery without having to use their hands or take their eyes off the patient.
Paul Szotek, MD, led the surgical team at Indiana University Health … read more »
