Radiation exposure monitoring needs a personal touch July 28, 2016 -- Yes, good software can go a long way. But it takes people to really make a radiation dose-monitoring initiative successful, according to a July 27 webinar co-sponsored by the Society for Imaging Informatics in Medicine and the European Society of Medical Imaging Informatics.
COPD severity mirrors lung cancer incidence July 28, 2016 -- A new analysis of patients who participated in the National Lung Screening Trial shows a clear relationship between the severity of chronic obstructive pulmonary disease (COPD) and lung cancer incidence at screening. The findings suggest that COPD patients should be included in CT lung screening programs.
Survey finds CTA use has surged since 2001 July 26, 2016 -- Driven by dramatic growth in chest exams and the number of studies performed in the emergency department, utilization of CT angiography (CTA) exams in the Medicare population has skyrocketed over the past 13 years, according to new research from the Harvey L. Neiman Health Policy Institute.
Radiologists show no radiation-related mortality risk July 19, 2016 -- Radiologists who started practice after 1940 face no increased risk of mortality compared to other physicians who aren't exposed to radiation as part of their jobs, according to a large new study published July 19 in Radiology. The results are a credit to long-term efforts to reduce occupational radiation exposure, the researchers said.
C-RADS reporting adds value to CT colonography July 18, 2016 -- The use of the CT Colonography Reporting and Data System (C-RADS) has brought a standardized approach to risk assessment and management of findings both inside and outside the colon, paving the way to high-quality population-based colorectal cancer screening, according to an article in the Journal of the American College of Radiology.
Very low calcium scores do not guarantee negative MPI July 12, 2016 -- Symptomatic patients with very low coronary artery calcium scores are almost as likely to have a positive SPECT myocardial perfusion imaging (MPI) scan and a subsequent cardiac event as patients with higher calcium scores, according to a study presented at the Society of Nuclear Medicine and Molecular Imaging annual meeting.
Lancet study maps 2015 MERS outbreak in South Korea July 8, 2016 -- A single patient transmitted the Middle East respiratory syndrome coronavirus (MERS-CoV) to nearly half of those infected with the virus during the 2015 outbreak in South Korea, according to a study published online on July 8 in Lancet.
Annual CT follow-up is safe for nonsolid lung nodules July 5, 2016 -- It's safe to track patients with nonsolid nodules detected on CT lung cancer screening with annual low-dose CT -- mitigating the need for biopsy or surgery of these lesions, according to a new study published online July 5 in Radiology.
CT technique tames Tower of Babel from different IR schemes July 1, 2016 -- The use of iterative reconstruction (IR) is leading to ever-lower levels of CT radiation dose. But it's also creating a modern-day Tower of Babel when comparing scans reconstructed with different IR schemes. Fortunately, a talk at the recent International Society for Computed Tomography 2016 Symposium revealed how to tame the confusion.
What does the Joint Commission really want with CT? June 28, 2016 -- Radiology departments may think complying with the Joint Commission's 2015 accreditation standards for CT is an overwhelming undertaking, but it's not as hard as it seems, according to a presentation given at the recent International Society for Computed Tomography 2016 Symposium in San Francisco.
New up-and-coming healthcare offerings that make use of CT -- mobile stroke units and spectral CT -- occupied two spots on a list of new healthcare trends to watch in 2016, published by healthcare consultancy ECRI Institute. Read more
