Supplemental ultrasound screening for all U.S. women with dense breasts would substantially increase healthcare costs with little improvement in overall health, according to senior author Anna Tosteson, ScD, at Dartmouth Hitchcock’s Norris Cotton Cancer Center and The Dartmouth Institute for Health Policy and Clinical Practice.
In a study recently released in the Annals of Internal Medicine, Tosteson and colleagues, including lead author Brian Sprague, MD, provide evidence on the benefits and harms of adding ultrasound to breast cancer screening.
According the the American Heart Association, exposure to radiation of the heart should be discussed among referring and performing physicians in order to effectively counsel the patient on radiation risks and benefits so that the patient can truly give informed consent.
According to a clinical study conducted at 15 medical centers, and published in the New England Journal of Medicine, CT scans are no better than the less-often-used utltrasound exams when diagnosing kidney stones. Unlike ultrasound, CT exposes patients to significant amounts of radiation. While CT is a preferred choice in the emergency room, the ultrasound is a better place to start the initial diagnostic imaging test.
X-RAY CE is proud to release Spine Imaging, 3rd Edition, a continuing education course for imaging professionals. Offering 12 Category A+ credits that are ASRT approved, this course discusses 200 case studies to challenge the imaging professional’s knowledge on a full range of topics in spine imaging. Each case includes images, supporting literature references, and a commentary to help gain a better understanding of how the correct diagnosis was reached. Emphasis on pathological conditions and clinical features are discussed as well.
Spine Imaging, 3rd Edition is available as a traditional home study course and as an E-Course for $94.95 and includes book or ebook, posttest and online testing using X-RAY CE’s online testing center.
X-RAY CE has been assisting imaging professionals with their continuing education needs since 2001 and has one of the largest selections of course modalities for the x-ray industry.

It can take several months to measure how effective treatment is for Cystic Fibrosis, the early-fatal lung disease, but now a new imaging method allows live viewing to monitor treatment. “Because we will be able to see how effectively treatments are working straight away, we’ll be able to develop new treatments a lot more quickly, and help better treat people with cystic fibrosis,” said lead researcher, Dr Morgan.
A study published in Cancer found that the number of people diagnosed with advanced-stage breast cancer has decreased by 37 percent since health care providers begain using mammography. Researchers from the University of Michigan produced the report. The study also found that the number of early-stage diagnoses increased 48 percent.
The Mayo Clinic is leading a collaborative effort to ensure a national protocol is put into action to ensure that children receive the right exam, ordered the right way with the right radiation dose. A commentary, published online in the Journal of Patient Safety, calls for the American College of Radiology, the Joint Commission, the Intersociety Accreditation Commission, and the Centers for Medicare and Medicaid Services to require three safety practices for accreditation of all American hospitals and advanced diagnostic imaging facilities.
A simple diagnostic algorithm for pediatric acute appendicitis decreased the use of imaging, including CT, without reducing diagnostic accuracy, according to a study presented earlier this year in Surgery online. “Given the concern for increased risk of cancer after CT, these results support use of an algorithm in children with suspected appendicitis,” wrote the authors.
A quality assessment and improvement project at the Veterans Affairs Puget Sound Health Care System in Seattle revealed the need for optimization of the imaging experience of patients with posttraumatic stress disorder (PTSD) and a viable area for improved awareness and future research, according to a feature published in the June issue of the Journal of the American College of Radiology.
Many patients with PTSD require diagnostic imaging for workup of medical problems, yet radiologic examinations could invoke anxiety, fear or discomfort in this demographic.
Researchers from Western University’s Robarts Research Institute have developed a new application called quantitative susceptibility (QS) magnetic resonance imaging (MRI) to monitor specific areas of the brain. The application provides a better way to monitor multiple sclerosis at its earliest stages.
“Our research provides a quantitative tool using a relatively conventional imaging sequence but with novel analysis. This tool shows that there is considerable damage occurring in common areas of all patients in both the white matter and in the deep brain structures—the gray matter. Those quantitative measures—what we call quantitative susceptibility—correlate with disease symptoms,” states Dr. Menon of the research team.
