IBD patients benefit from routine colonoscopies

Patients with irritable bowel disease who underwent recent routine colonoscopies are less likely to develop colorectal cancer and die from the disease after a cancer diagnosis, according to a study delivered last week at the annual meeting of the American College of Gastroenterology in Philadelphia.

CT angiography a life saver for suspected heart disease patients

The use of computed tomography coronary angiography (CTA) in patients with suspected coronary artery disease (CAD) improves outcomes and contributes to improved survival, according to a new study published in the journal Atherosclerosis.

Radiology practices use data analytics to boost performance

The use of data analytics is becoming increasingly common in the world of radiology, as demonstrated in a recent article in Diagnostic Imaging that examined how radiology practices can use data in real-world situations to improve their performance.

Over-imaging of children: The discouraging pattern continues

Last year, a study published in JAMA Pediatrics evaluated the use of CT scans between 1996 and 2010 in children younger than 15 years and found that between 1996 and 2005 the use of CT doubled among children younger than 5 years old, and almost tripled for older children. The good news in that study was that even though the rate of CT imaging on children remained high, it declined in the period between 2005 and 2010. It seemed that efforts to reduce children's exposure to ionizing radiation through campaigns like Image Gently were having an effect.

That's why the results of new research out of Cincinnati Children's Hospital Medical Center, reported in this week's issue of FierceMedicalImaging, are so discouraging.

 

Tomosynthesis effective for finding cancer, reducing recall rates for women under 50

Digital breast tomosynthesis (DBT) is effective in reducing patient recalls and detecting cancers when compared to digital mammography, but is even more effective when used to screen women under the age of 50, according to a study published in October 13 in the Journal of the National Cancer Institute.

Pediatricians order too many head CT scans for children

Children with concussion symptoms are still undergoing too many CT scans according to a study out of Cincinnati Children's Hospital Center.

New PET imaging technique IDs dangerous bacteria

Researchers at Johns Hopkins are combining a PET scanner with a chemical tracer to detect and monitor, in real time, dangerous bacteria inside the body.

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.
