Radiation alarm Bleeper Sv reduces dose to cardiac cath staff
December 23, 2014 -- A beeping radiation dose monitor that is worn by healthcare personnel during cardiac catheterization procedures successfully reduced dose in a trial conducted by Texas researchers. Called Bleeper Sv, the monitor emits a warning sound that becomes louder and more frequent as exposure to radiation grows -- giving personnel a chance to modify their work habits to reduce dose.

RAND study questions whether decision support really works
December 18, 2014 -- Decision support for physicians ordering imaging exams has been touted as an effective way to reduce unnecessary imaging and ensure the appropriateness of studies. However, a new report released by RAND that evaluated a Medicare demonstration project of decision support suggests it may not be as helpful as it's cracked up to be.
Nonsolid lung nodules found on CT screening harbor few cancers
December 18, 2014 -- Nonsolid nodules detected with CT lung cancer screening are often indolent, and even when they do harbor cancer, the long lead times before such nodules develop make it safe to follow them up less often, according to new long-term data presented at the RSNA 2014 meeting.
Philips targets image-guided therapy with 1.2B bid for Volcano
December 17, 2014 -- Continuing an aggressive expansion of its image-guided therapy and interventional radiology business, Philips Healthcare has inked a deal to pay $1.2 billion to acquire Volcano, a developer of intravascular ultrasound and fractional flow reserve technology.
