Researchers using ultrasound to measure abdominal aortic aneurysms

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.

How appropriate are ACR's appropriateness criteria?

Back in the 1990s the American College of Radiology began a huge project to define the appropriate use of different imaging technologies. This effort--the ACR Appropriateness Criteria--is continually updated and covers all medical procedures, helping healthcare providers conduct the most appropriate medical imaging exam for a patient's clinical condition. Recent research shows us, however, that some work still needs to be done when it comes to the use of appropriateness criteria.   

Stanford researchers using ultrasound to power internal medical devices

Engineers at Stanford University are working on ways to use ultrasound to send power--safely and wisely--to "smart chips" programmed to monitor a person's health or treat pain.

Interruptions lead to mistakes by radiology residents

Interruptions in the form of telephone calls increase the possibility that radiology residents can make mistakes in creating preliminary reports, according to an article published online in  Academic Radiology.

Quick colonoscopy follow-up leads to overuse

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.

Most adults unaware of connection between breast density and cancer

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.

Cardiac imaging: Educating physicians and empowering patients

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.

CAD has little effect on radiologists' diagnoses

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.

Study: Large increase in unnecessary cardiac stress testing with imaging

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.

New MRI technique detects dementia before symptoms appear

A new MRI technique can be used to detect dementia before patients show signs of mental decline.
