July 2012 Briefing - RadiologyLast Updated: August 01, 2012.
Here are what the editors at HealthDay consider to be the most important developments in Radiology for July 2012. This roundup includes the latest research news from journal articles, as well as the FDA approvals and regulatory changes that are the most likely to affect clinical practice.
Study Assesses Impact of Lesion Severity on Coronary Event Risk
FRIDAY, July 27 (HealthDay News) -- Contrary to previous evidence, angiographic lesion severity may predict subsequent risk of ST-segment elevation myocardial infarction (STEMI) within three months, according to a study published in the July 15 issue of The American Journal of Cardiology.
Coronary CT Angiography in ER Ups Decision-Making Efficiency
WEDNESDAY, July 25 (HealthDay News) -- Incorporating coronary computed tomographic angiography (CCTA) into evaluation of patients presenting to the emergency department with acute coronary syndrome symptoms improves the efficacy of clinical decision making, according to a study published in the July 26 issue of the New England Journal of Medicine.
Most Doctors Satisfied With Electronic Health Records
THURSDAY, July 19 (HealthDay News) -- Although only 55 percent of physicians had adopted electronic health records (EHRs) in 2011, most are somewhat or very satisfied with their system and most report enhanced patient care, according to a July data brief issued by the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS).
Swedish Study Questions Value of Mammography Screening
THURSDAY, July 19 (HealthDay News) -- County-specific mortality statistics from Sweden indicate little benefit of mammography screening on breast cancer mortality, according to a study published online July 17 in the Journal of the National Cancer Institute.
Poorer Patient Experience at Safety-Net Hospitals
THURSDAY, July 19 (HealthDay News) -- Safety-net hospitals (SNHs) perform worse on nearly every measure of patient experience, according to a study published online July 16 in the Archives of Internal Medicine.
Adding Stroke Severity Measure Improves Mortality Risk Models
TUESDAY, July 17 (HealthDay News) -- Adding stoke severity to a hospital 30-day mortality risk model improves model discrimination and hospital performance rankings, according to a study published in the July 18 issue of the Journal of the American Medical Association.
Social Network Analysis IDs Informal Physician Networks
TUESDAY, July 17 (HealthDay News) -- Informal networks among physicians who share patients demonstrate substantial geographic variability, while within networks, physician and patient characteristics are similar, according to a study published in the July 18 issue of the Journal of the American Medical Association.
Sodium Accumulation Noted in Brain in Multiple Sclerosis
TUESDAY, July 17 (HealthDay News) -- Use of sodium 23 (23Na) magnetic resonance imaging (MRI) has identified dramatic increases in total sodium concentration (TSC) in the brain of patients with advanced relapsing-remitting multiple sclerosis (RR MS), with increased sodium in gray matter correlating with disability, according to a study published online July 17 in Radiology.
Brain Tracer Indicates Risk of Future Cognitive Decline
FRIDAY, July 13 (HealthDay News) -- A radioactive tracer that can image amyloid-beta deposits in the brain can indicate whether older adults are at risk of cognitive decline and developing Alzheimer's disease, according to a study published online July 11 in Neurology.
Trackable Blood Cells Feasible for MRI Monitoring
WEDNESDAY, July 11 (HealthDay News) -- Blood cells labeled with superparamagnetic particles of iron oxide (SPIO) are safe and can be tracked by magnetic resonance imaging (MRI), which may allow better monitoring of cell-based therapies, according to a study published online July 10 in Circulation: Cardiovascular Imaging.
Screening Men for Abdominal Aortic Aneurysm Cost-Effective
MONDAY, July 9 (HealthDay News) -- For 65-year-old men, screening for abdominal aortic aneurysm is cost-effective, and rescreening should be considered for high-risk men, according to a study published online July 5 in BMJ.
Automated Variation Measure Indicates Risk of Breast Cancer
FRIDAY, July 6 (HealthDay News) -- A variation measure, estimated from an automated algorithm of the grayscale variation within a mammogram, correlates with the risk of breast cancer as strongly or more so than percent density (PD), according to a study published online July 3 in the Journal of the National Cancer Institute.
Fingolimod Slows Progress of Multiple Sclerosis
THURSDAY, July 5 (HealthDay News) -- For patients with remitting-relapsing multiple sclerosis, fingolimod correlates with reduced inflammatory activity, tissue damage, and brain volume loss, as indicated by measures on magnetic resonance imaging (MRI) over a two-year period, according to a study published online July 2 in the Archives of Neurology.
Patient Decision Aid Beneficial in Papillary Thyroid Cancer
THURSDAY, July 5 (HealthDay News) -- Patients with early-stage papillary thyroid cancer (PTC) may benefit from the use of a patient-directed computerized decision aid (DA) to provide medical knowledge and resolve decisional conflicts regarding the use of adjuvant radioactive iodine (RAI) treatment, according to research published online July 2 in the Journal of Clinical Oncology.
CT Colonography Is a Viable Screening Test in Older Adults
MONDAY, July 2 (HealthDay News) -- For older patients who undergo computed tomography colonography (CTC), the rates of referral to colonoscopy and prevalence of advanced neoplasia are low, according to a study published in the July issue of the American Journal of Roentgenology.
