Sonographers exposed to radiation from MPI patients
April 17, 2018 -- A new study found that sonographers who performed cardiac ultrasound studies on patients who received nuclear myocardial perfusion imaging (MPI) scans were exposed to residual radiation from the patients. While the radiation levels were low, the researchers advised that sonographers modify their scanning techniques.  Discuss
New Alzheimer's definition relies on imaging biomarkers
April 17, 2018 -- New research guidelines for classifying whether individuals have Alzheimer's disease rely heavily on the use of biomarkers from imaging scans. The new framework was published in the April issue of Alzheimer's & Dementia: The Journal of the Alzheimer's Association.  Discuss
How can unnecessary ABUS recalls be avoided?
April 16, 2018 -- Automated breast ultrasound (ABUS) can yield lower recall rates than handheld ultrasound, but unnecessary recalls still occur -- and it's important to find ways to reduce them, according to research presented at the recent American Institute of Ultrasound in Medicine annual meeting in New York City.  Discuss
Should you change PACS vendors? 10 reasons to consider
April 16, 2018 -- Given the challenges involved, why would anyone want to switch PACS vendors? In this article, informatics expert Herman Oosterwijk of OTech gives his top 10 reasons based on discussions with PACS professionals and feedback from his PACS administrator students.  Discuss
Flexible 3D-printed heart replicates size, texture
April 13, 2018 -- Researchers from Australia and China have created a 3D-printed heart that mirrors the size and texture of real cardiac tissue, with potential clinical applications in patient and medical education, communication among clinicians, and presurgical planning, according to a recent study published in PLOS One.  Discuss
DBT improves breast cancer screening in young women
April 13, 2018 -- Adding digital breast tomosynthesis (DBT) to digital mammography improves breast cancer screening in women younger than 50, decreasing recalls and finding more cancers in those who have dense tissue, according to a study published online April 9 in the American Journal of Roentgenology.  Discuss
Multiparametric MRI shines for suspected breast cancer
April 13, 2018 -- Dynamic contrast-enhanced MRI and diffusion-weighted imaging each have advantages and disadvantages for assessing suspicious breast lesions. The optimal approach is multiparametric MRI using both methods, according to a new study published online in Investigative Radiology.  Discuss
Lung cancer risk model optimizes follow-up CT screening
April 12, 2018 -- How might a lung cancer risk-prediction model improve follow-up CT screening? A model that incorporates patient characteristics and CT data could allow many individuals to skip the first annual follow-up screening exam -- reducing costs and radiation exposure, according to research published online recently in Thorax.  Discuss
DOJ action may hinder disabled access to imaging
April 12, 2018 -- The U.S. Department of Justice (DOJ) has withdrawn a key guidance related to the Americans with Disabilities Act, endangering efforts to ensure that people with disabilities can access medical equipment such as imaging systems, according to an editorial published April 12 in the New England Journal of Medicine.  Discuss
Deep learning performs superresolution MSK MRI
April 11, 2018 -- A deep-learning algorithm can transform low-resolution, thick-slice knee MR images into high-resolution, thin-slice images -- potentially yielding faster image acquisition, lower costs, and fewer motion artifacts in musculoskeletal MRI, according to research published online in Magnetic Resonance in Medicine.  Discuss
