Researchers at Purdue University's Weldon School of Biomedical Engineering are investigating how ultrasound can be used to study abdominal aortic aneurysms, the 13th leading cause of death in the U.S.
With the Centers for Medicare & Medicaid Services poised to make a decision about coverage of low dose CT screening for lung cancer, two editorials published online last week in JAMA Internal Medicine took another look at an issue that continues to generate a lot of controversy.
A study by researchers at Brigham and Women's Hospital in Boston has found that endoscopists commonly recommend shorter follow-up intervals than colonoscopy guidelines recommend, leading to an overuse of the procedure.
A survey of 10,000 adults in 10 countries has found that only about one-fourth are aware that women with high breast density are more likely to develop breast cancer.
Today, cardiac imaging accounts for about 40 percent of patient radiology exposure, and there have been concerns expressed that many cardiologists haven't been fully aware of the risks associated with ionizing radiation and cardiac imaging. In this week's issue of FierceMedicalImaging we report on research that further illustrates the impact cardiac imaging can have on patient radiation exposure. The study, published in the Annals of Internal Medicine, found that the overuse of cardiac stress testing over the course of nearly two decades has resulted in the performance of about 1 million unnecessary tests (most of them conduced with imaging) at a cost of about half a billion dollars.
Radiologists rarely change their diagnoses after using computer-aided detection systems with digital mammography, according to a study published this month in the American Journal of Roentgenology.
The overuse of cardiac stress testing with imaging has led to unnecessary healthcare spending, as well as increased patient exposure to radiation, according to a study in the Annals of Internal Medicine.
A new MRI technique can be used to detect dementia before patients show signs of mental decline.
Last year the New York Times created quite a media storm with an article in which it reported on colonoscopies that ranged in price--depending on the location--from $7,563.56 to $19,438 (including a polyp removal).
Education, justification and optimization are the cornerstones upon which radiation safety efforts related to cardiovascular imaging should be based, according to a scientific statement issued by the American Heart Association.
