AI-based model aids fMRI in ADHD detection

December 11, 2019 -- A newly developed deep-learning artificial intelligence (AI) model is lending a helping hand to radiologists reading functional MRI (fMRI) scans, helping them better predict attention deficit hyperactivity disorder (ADHD), according to a study published online December 11 in Radiology: Artificial Intelligence. Discuss

Can FDG-PET/MRI replace biopsy in breast cancer cases?

December 11, 2019 -- Although FDG-PET/MRI shows promise for accurate staging of breast cancer, the modality still isn't as accurate as sentinel lymph node biopsy, according to a study presented last week at RSNA 2019 in Chicago. Discuss

Massive VHA audit explores reasons for imaging delays

December 10, 2019 -- A massive review of outpatient radiology and nuclear medicine services in the U.S. Veterans Health Administration (VHA) found that 17% of routine requests and 25% of urgent orders for outpatient imaging were not performed in a timely fashion. Discuss

USPSTF reaffirms take on ultrasound AAA screening

December 10, 2019 -- The U.S. Preventive Services Task Force (USPSTF) has reaffirmed with no major changes its 2014 recommendations on using ultrasound to screen for asymptomatic abdominal aortic aneurysm (AAA), in a new statement published online December 10 in the Journal of the American Medical Association. Discuss

FFDM may beat analog and CR for breast cancer screening

December 10, 2019 -- Full-field digital mammography (FFDM) detects breast cancer better than either analog film-screen mammography or computed radiography (CR), regardless of age, breast density, or screening round, according to a South Korean retrospective study of over 8 million women published online on December 3 in Radiology. Discuss

PET and prejudice: Insurance firms' misconceptions

December 10, 2019 -- Healthcare insurance companies should value PET imaging and its cost-effective contributions to patient outcomes rather than view the modality as too expensive and unworthy of reimbursement, according to an editorial in the December issue of the Journal of Nuclear Medicine. Discuss

PET rules out need for radiotherapy in lymphoma patients

December 10, 2019 -- Most patients with diffuse large B-cell lymphoma who have a clear PET scan can safely skip radiation treatment, according to a study funded by the U.S. National Cancer Institute that was presented December 8 at the 2019 American Society of Hematology conference in Orlando, FL. Discuss

Are clinicians overusing CTA for carotid stenosis?

December 9, 2019 -- The use of CT angiography (CTA) as the first-line imaging exam for carotid artery stenosis has increased nearly threefold during the past several years, raising concerns over growing patient costs and radiation exposure, according to a study presented on Friday at RSNA 2019. Discuss

ABUS delivers better diagnostic performance

December 9, 2019 -- Both automated breast ultrasound (ABUS) and traditional handheld ultrasound can significantly improve breast cancer detection when used as an adjunct to mammography in women with dense breasts. But ABUS yields better diagnostic performance, according to research presented at RSNA 2019 in Chicago. Discuss

AR, 3D printing make waves in cardiac care

December 6, 2019 -- CHICAGO - What are the distinct benefits of 3D printing and augmented reality (AR) in the management of cardiac conditions, and what clinical scenarios are the technologies best suited for? Radiologists from Poland and Canada discussed these questions and more in a Thursday educational session at RSNA 2019. Discuss
