Lung plus head/neck cancer screening delivers high yields January 15, 2015 -- Head and neck cancer is too rare to screen for in the general population, but using CT to screen those who are also being checked for lung cancer draws a relatively high yield of malignancies, according to an analysis published online in Cancer.
CAD for breast CT is improved with spiculation detection January 15, 2015 -- University of Chicago researchers significantly improved the performance of their computer-aided detection (CAD) algorithm for breast CT studies by having it detect lesion spiculation automatically, according to a new study.
PET/MRI spots neuroinflammation from chronic back pain January 15, 2015 -- PET/MR images have led researchers for the first time to confirm evidence of neuroinflammation in key regions of the brain in patients with chronic back pain, according to a study published online January 12 in Brain.
Annual DBT screening could slash health costs, study finds January 14, 2015 -- By reducing recalls and catching breast cancer earlier, digital breast tomosynthesis (DBT) could yield hundreds of millions of dollars in U.S. healthcare cost savings if it were added to mammography for annual breast cancer screening, according to a new study conducted by Truven Health Analytics.
Twitter posts highlight patient fears over CT radiation risk January 14, 2015 -- If tweets are any indication, many patients are concerned about the issue of CT radiation dose risk, and radiologists need to get more involved on Twitter to alleviate these concerns, according to a new study published in the American Journal of Roentgenology.
CT's expansion puts emphasis on dose in Middle East January 14, 2015 -- At least 11 new CT scanners are due to be installed between now and March across Dubai and the north of the United Arab Emirates, and such rapid growth means the authorities are putting renewed emphasis on radiation protection and patient safety.
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.
