Prototype FFR-CT software shows high accuracy vs. invasive FFR
October 2, 2014 -- A software-based technique aimed at deriving CT-based blood flow data without invasive procedures showed similar accuracy to invasive fractional flow reserve (FFR) for determining the significance of coronary stenosis, according to a new report in the American Journal of Cardiology.
Move over tomo? Dedicated breast CT has bright future
October 1, 2014 -- Although it's still an investigational modality, dedicated breast CT offers distinct benefits for diagnostic workup compared to other imaging modalities, according to an article published online in the Breast Journal.
JAMA editorials seek middle ground in Medicare payment for CT lung screening
September 30, 2014 -- Two new editorials in the Journal of the American Medical Association suggest new ways to navigate the gulf between advocates and skeptics of CT lung cancer screening by placing limitations -- for now, at least -- on the screening of Medicare-aged smokers.
MDCT study ties aortic calcification to mortality
September 26, 2014 -- Both total aortic calcium load and calcium density measured by MDCT are associated with increased mortality risk, according to a new study in the September 23 issue of the Journal of the American College of Cardiology.
Survey: Patients unfazed by false positives on CTC exams
September 24, 2014 -- In a new survey, patients said they believe the benefits of having a malignancy detected on colon screening exams more than outweigh the drawbacks of a false positive, even if it would lead to unnecessary imaging or invasive follow-up, according to an article published in the October issue of Radiology.
Big spectral CT project launches in New Zealand
September 22, 2014 -- You've heard of dual-energy CT, but how about eight-energy CT? That's the goal of researchers in New Zealand, who this month received funding for a project to build a CT scanner capable of detecting eight different energies at once in scans of humans. They hope the new spectral scanner will offer functional imaging that is unprecedented for CT, with a lower radiation dose to boot.
Ultrasound should be 1st choice for suspected kidney stones
September 18, 2014 -- Ultrasound should still be the first imaging test of choice for evaluating patients with suspected nephrolithiasis, according to research published in this week's issue of the New England Journal of Medicine. The study found that using CT first didn't yield better clinical outcomes.
ICR: Survey reveals major knowledge gaps on radiation dose
September 15, 2014 -- DUBAI - The lack of knowledge among medical staff about radiation dose -- specifically for CT scans -- remains a serious concern, and patients still receive very little information about the pros and cons of scans, according to a survey presented at the International Congress of Radiology (ICR).
Perfusion CT's great potential remains unrealized
September 15, 2014 -- Challenges remain on the road to more precise assessment of tumor treatment response with CT perfusion, but the techniques are already robust and far more sensitive than the old methods based on tumor size. In this emerging field, tumor biology and treatment response combine to make CT an ideal modality for monitoring cancer treatment, according to Boston researchers.
New studies of Egypt's mummies rest on government go-ahead
September 12, 2014 -- DUBAI - Imaging investigations of ancient Egypt's royal mummies may start again in the near future, but this depends on getting the all-important green light from the country's senior politicians, according to the head of the medical team that has conducted previous examinations.
