Diagnostic Imaging

Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

Elbow pain in baseball players better diagnosed with dual-modality imaging

Baseball players experiencing medial elbow pain are more precisely imaged by a combination of stress ultrasound and magnetic resonance arthrography (MRA) than by either of those two modalities alone, even though the latter modality is widely considered the gold standard in its own right.

Breach in blood-brain barrier after stroke could mean more severe bleeding after treatment

A new study from the National Institutes of Health’s National Institute of Neurological Disorders and Stroke shows that stroke patients who have more severe breaches of the blood-brain barrier might be at greater risk for severe bleeding in the brain after invasive stroke treatment. 

Cancer physicians want pediatricians to increase use of HPV vaccine

Oncologists are putting pressure on pediatricians to more strongly recommend the HPV vaccine, saying their endorsement will help prevent cancer decades down the line.

Knee osteoarthritis best imaged with patient standing, bearing own weight

Two Danish researchers have shown that it’s crucial to x-ray suspected osteoarthritis in the knee with the patient in a standing, weight-bearing position rather than a supine, non-weight-bearing position.

CT colonography can’t compete with colonoscopy on some high-risk polyps

Polyps characterized as both sessile and serrated lead to as many as 30 percent of all colorectal cancers, and they’re very good at avoiding detection by CT colonography—while quite readily giving themselves up to colonoscopy—according to a study published earlier this spring in the American Journal of Gastroenterology.

Cerebral microbleeds and dementia: Number and location matter

Building on prior research establishing the prevalence of cerebral microbleeds in Alzheimer’s patients, investigators in the Netherlands have used MRI in a large, longitudinal study to show that the related extent of cognitive decline and dementia depends on how many bleeds the patient has and where they’re located within the brain. 

The hunt is on for imaging biomarkers of ovarian cancer

A researcher at the University of Arizona is spearheading an effort to come up with a reliable way to catch ovarian cancer in its earliest stages. 

Vermont breast density bill signed into law

Governor Peter Shumlin signed Vermont’s breast density reporting bill into law this week, making it the 28th state to have such legislation in place.

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
