Chest CT referrals from x-ray yield high rate of abnormalities
December 23, 2014 -- Nearly half of patients who receive radiologist recommendations for chest CT to evaluate abnormal findings on chest radiography have clinically relevant findings at CT, including a substantial number of new malignancies, according to a new study in Radiology.
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.
New 2015 instructions for image-guided breast biopsies
December 22, 2014 -- The American Medical Association has made a few important changes to CPT codes related to image-guided breast biopsies, and providers may not know these updates exist, explains Jeff Majchrzak of Panacea Healthcare Solutions in his new article.
Novel CT technique emerges for acute appendicitis
December 22, 2014 -- Abdominal CT with compression to the right lower quadrant has a high diagnostic accuracy in cases of acute appendicitis, and it can be considered as a CT counterpart of graded compression ultrasound, Turkish researchers reported at the recent RSNA 2014 meeting.
Could reverse auctions boost purchasing power in radiology?
December 19, 2014 -- Two years after introducing the concept of reverse auctions to buy capital medical imaging equipment, Reverse Radiology has launched a website to give radiology departments and imaging centers more purchasing leverage.
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.
US elastography offers clues to middle-age Achilles injury risk
December 17, 2014 -- Shear-wave ultrasound elastography studies may be able to shed light on why middle-aged adults face an increased risk of Achilles tendon injuries, according to research from the University of Wisconsin School of Medicine and Public Health.
FDA warns against keepsake fetal US, heartbeat monitors
December 16, 2014 -- The U.S. Food and Drug Administration has issued a consumer update to strongly discourage pregnant women from obtaining fetal keepsake ultrasound images and videos, as well as using over-the-counter Doppler fetal ultrasound heartbeat monitors.
Gamma Medica sets sights on continued progress in 2015
December 16, 2014 -- Molecular imaging developer Gamma Medica is hoping that 2015 will be a watershed year in its resurrection, some 21 months after emerging from Chapter 11 bankruptcy. The company has refreshed its technology and is building its installed base as it regains its footing.
CT ties emphysema to mortality, independent of other risks
December 15, 2014 -- CT scans show that people with emphysema are at risk of earlier death than those without the disease, even if they have no evidence of chronic obstructive pulmonary disease or airflow obstruction, according to a study published on Monday in the Annals of Internal Medicine.
Tomosynthesis classifies breast lesions more accurately
December 15, 2014 -- Adding digital breast tomosynthesis to digital mammography for screening appears to have many benefits, including greater sensitivity in dense breast tissue and fewer recalls. But the technology also classifies noncalcified breast lesions more accurately in the diagnostic setting, according to research presented at RSNA 2014.
Study confirms imaging's shift from offices to hospitals
December 12, 2014 -- As policymakers attempt to curb healthcare costs, the use of advanced imaging -- MR, nuclear medicine, and CT -- has been shifting from private offices to hospital outpatient departments. So how might this trend affect patients?
