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 »

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 »

That information comes from a report published last week by the U.S. Food and Drug Administration’s Center for Devices and Radiological Health (CDRH). The increase in recalls of radiology devices had to do with greater awareness of radiation … read more »

Health insurers should provide financial incentives for physicians to try ultrasound imaging first, before they think about other imaging modalities, according to Kevin M. Goodwin.

Of course, Goodwin may be a bit biased. He’s president and chief executive officer of SonoSite, which makes point-of-care ultrasound equipment. SonoSite has been one of the main drivers behind the American Institute of Ultrasound In … read more »
