Showing patients their cardiac scans can have major impact

December 3, 2018 -- Swedish researchers of a large study have found that showing patients visible signs of arterial atherosclerosis and plaque on their own ultrasound scans can help reduce the risk of cardiovascular disease a year later. Their article was published online on 3 December in the Lancet. Discuss

Is an accurate two-minute biopsy viable?

December 3, 2018 -- Performing a reliable and cost-effective biopsy in less than two minutes is now possible, thanks to a noninvasive and nondestructive real-time optical imaging device, the head of Paris-based company LLTech Imaging claimed during RSNA 2018. Discuss

U.S.-Swiss study adds to concerns on gadolinium

November 30, 2018 -- CHICAGO - Increased signal intensities in different brain regions, presumably caused by linear and macrocyclic gadolinium-based contrast agents, may be an indication that gadolinium accumulation is more widespread than previously thought, a study presented on Wednesday at RSNA 2018 has found. Discuss

Global team outlines how 3D x-ray can boost imaging

November 30, 2018 -- Two new approaches to creating 3D images using x-rays could improve screening for diseases and the study of very fast processes, as well as enable analysis of material properties and provide structural information of opaque objects with unprecedented detail, an international research team has discovered.

Fukushima study sheds light on childhood thyroid cancer

November 29, 2018 -- The latest results of mass ultrasound screening of children for thyroid cancer after the Fukushima disaster were published online on 29 November by JAMA Otolaryngology. The study provides vital data on thyroid cancer, but may lead to more demands outside of Japan for ultrasound scans in younger people, increasing the risk of overdiagnosis. Discuss

Italians test novel CT method to relieve back pain

November 29, 2018 -- CT-guided pulsed radiofrequency, which applies pulses of energy directly to nerve roots, may be an effective method for alleviating lower back pain for cases when more conservative treatment options fail to do so, according to a Tuesday presentation at RSNA 2018 in Chicago. Discuss

Momentum gathers behind MRI for lung cancer screening

November 28, 2018 -- CHICAGO - Nearly a decade ago, CT surpassed x-ray as the imaging modality of choice for lung cancer screening. But could there be an even better option for the test? Researchers from the U.S., Switzerland, and Germany made the case for MRI in a session on Monday at RSNA 2018. Discuss

How Denmark strives for quality in breast screening

November 27, 2018 -- Multidisciplinary teamwork, high-volume readers, training and audits, and continuous monitoring of quality are vital in breast cancer screening, according to Dr. Ilse Vejborg, a speaker at Tuesday's RSNA 2018 session on the Nordic countries. Her group also works hard to avoid potential harms from overdiagnosis and unnecessary intervention. Discuss
