Zika's spread shocks researchers | RTs and radiation protection | Have you voted yet?

Dear AuntMinnie Member,

Researchers studying the Zika virus in an animal model were shocked at how quickly the virus spread from an infected pregnant macaque monkey to its fetus, based on images acquired from MRI scans.

Zika's devastating impact on infants born to pregnant women infected with the virus has been well-documented. But less clear is the exact mechanism by which the virus spreads.

Researchers from the University of Washington used MRI scans to monitor a pregnant monkey infected with the virus, and they were surprised by the extent of brain anomalies in the fetus just 10 days after infection. They believe the virus traveled to the fetus through the placenta, and they noted that the fetus had higher virus levels in its brain than the mother did.

RTs and radiation protection

Are radiologic technologists (RTs) doing enough to protect themselves from radiation when performing fluoroscopically guided interventional radiology procedures?

It's a great question, and one that was addressed in a new study we're highlighting this week in our Digital X-Ray Community. Researchers from the U.S. National Cancer Institute tracked radiation protection practices followed by RTs over the decades to see how they had changed.

The upshot? RTs are doing a better job of following practices like wearing lead aprons and dose monitoring badges. But they are also performing more procedures now than in the past -- which could be increasing their exposure to radiation. Learn more by clicking here.
