B-mode ultrasound spots subclinical atherosclerosis January 13, 2015 -- Thanks to advances in automation and improved imaging capabilities, B-mode ultrasound can be used to assess subclinical atherosclerotic disease and better identify those patients who would benefit from medical intervention prior to symptom onset, according to research published in Global Heart.
Wireless mobile DR gets images into PACS faster than CR January 13, 2015 -- Researchers from Hong Kong were able to obtain mobile x-ray images in their PACS network 70% sooner using a wireless portable digital radiography (DR) unit rather than a mobile x-ray system equipped with computed radiography (CR) plates, according to a January 6 article in the Journal of Digital Imaging.
What's in a name? Vague image header info complicates sharing January 12, 2015 -- It's hard to find any institution that enjoys relying on CDs for image sharing purposes, but is everyone doing their part to usher in the new era of electronic image transmission? If research from MD Anderson Cancer Center is any indication, it doesn't appear that way.
Subtraction CTA boosts in-stent restenosis evaluation January 9, 2015 -- A new study of digital subtraction CT angiography (DSCTA) found that it vastly improved the visualization of the stent lumen by eliminating metallic artifacts, according to researchers from Japan. The technique was particularly effective in improving the assessment of very small stents.
New display calibration method may boost color image viewing January 8, 2015 -- Although color now pervades medical imaging, currently accepted calibration methods for imaging displays still rely on assessing gray levels. Display calibration may soon enter the color era, however, if a proposed extension to the DICOM Grayscale Standard Display Function is adopted.
ACR says OIG will scrutinize imaging in 2015 January 8, 2015 -- The U.S. Department of Health and Human Services' Office of Inspector General (OIG) has included three imaging-related projects in its work plan for the 2015 fiscal year, according to the American College of Radiology (ACR).
Could brain imaging predict future behavior? January 7, 2015 -- It may sound like something out of the technothriller "Minority Report," but could medical imaging modalities such as functional MRI someday be used to predict future behavior, such as someone's propensity to commit a crime? Maybe, but discoveries so far have fallen short of realizing imaging's potential in this regard, according to an article published January 7 in Neuron.
Half of Calif. primary care docs unaware of breast density law January 7, 2015 -- Half of California's primary care physicians are unaware of the state's breast density notification law, which suggests that the legislation has been unsuccessful in promoting discussions between women and their caregivers about breast cancer risk, according to a new study published in the Journal of the American College of Radiology.
CAD for virtual monochromatic CTC images shows high accuracy January 6, 2015 -- A computer-aided detection (CAD) algorithm analyzed virtual monochromatic dual-energy CT colonography (CTC) images accurately with few false positives in a study from Massachusetts General Hospital. The researchers believe the study could pave the way to more accurate minimal-prep CTC.
Tomo plus digital mammography decreases recalls by 37% January 5, 2015 -- Adding tomosynthesis to digital mammography for breast cancer screening reduces recall rates by 37%, with the technique recording better performance for certain types of breast abnormalities, according to a new study in the January issue of Radiology.
ACS: Cancer deaths drop 22% over 2 decades January 2, 2015 -- The American Cancer Society (ACS) recently reported that there has been a 22% drop in mortality from cancer in the U.S. over the past two decades, a decline that translates into the avoidance of over 1.5 million cancer deaths.
AJR: CT shows evidence of lung cancer spread via airways December 30, 2014 -- New research with CT supports the hypothesis that lung adenocarcinoma may spread through the airways and not just through the blood. So-called aerogenous metastasis of lung cancer has implications for staging, management, and prognosis and may be underrecognized, the authors report in the American Journal of Roentgenology.
Top 10 AuntMinnie stories for 2014 December 30, 2014 -- We're pleased to offer the top 10 stories on AuntMinnie.com for 2014, as measured by member traffic. Articles on breast screening dominated the headlines in 2014, with four of our top stories pertaining to breast imaging in one way or another.
JACR: Radiology can learn from the hospitality industry December 29, 2014 -- The patient experience has become an increasingly important issue in healthcare, as delivery models shift from volume- to value-based. But what exactly makes a patient's imaging experience positive? The hospitality industry can offer some insights, according to research published online in the Journal of the American College of Radiology.
