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. 

 

Study finds imaging appropriateness criteria should be modified, expanded

A review of appropriateness criteria of outpatient abdominal and pelvic CT and MRI exams published in Academic Radiology has found that of the exams matched with American College of Radiology appropriateness criteria, a high percentage were appropriate and more likely to lead to significant results than inappropriate studies.

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.

Dueling editorials argue merits of CMS LDCT lung cancer screening coverage

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.

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.

FDA officials: 3-D imaging technologies poised for breakthrough

The U.S. Food and Drug Administration has issued a consumer update detailing how the development of 3-D technologies are poised to change cancer detection.

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.

Stanford to hold free day of ultrasound instruction

Stanford University School of Medicine will host ULTRAfest Oct 18.--a full day of free ultrasound instruction open to any medical student in the county. Last year more than 300 students participated in the event.

Are physicians overpaid for performing colonoscopies?

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).

AHA names three cornerstones for cardiac imaging radiation safety

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.

Handheld ultrasound superior to physical examination for cardiac patients

Handheld ultrasound is more accurate and less expensive than physical examinations when used to diagnose patients with common cardiac abnormalities, according to a study published online in the Journal of the American College of Cardiology: Cardiovascular Imaging.

Pressure mounts on CMS to cover CT lung cancer screening

The pressure is piling up on the Centers for Medicare & Medicaid Services to cover low dose computed tomography for Medicare beneficiaries at high risk for lung cancer.

Researchers: Colonoscopy reimbursement reductions not the best way to cut health costs

Should efforts to cut down costs associated with colonoscopy include targeting the amount endoscopists should be reimbursed for performing the procedure?

Choosing Wisely for radiology: More than a conversation starter

When the Choosing Wisely campaign was launched in 2012, the stated goal of the initiative was to "spark conversation" about the necessity of certain frequently ordered tests and treatments. Currently, we are seeing evidence that Choosing Wisely recommendations--many of which are related to radiology and medical imaging--are, indeed, having an impact.
