Radiology is not immune to sexual harassment
May 10, 2017 -- As a specialty, radiology has historically had low rates of sexual harassment. But that doesn't mean the problem is resolved, according to a study published online April 28 in the Journal of the American College of Radiology.
USPSTF discourages thyroid cancer screening
May 9, 2017 -- Citing the lack of evidence for an overall benefit as well as the risk of harm from overdiagnosis and overtreatment, the U.S. Preventive Services Task Force (USPSTF) has finalized its recommendation against the use of screening with neck palpation or ultrasound for thyroid cancer in low-risk, asymptomatic adults.
CZT-based SPECT MPI may predict cardiac outcomes
May 9, 2017 -- SPECT gamma cameras featuring cadmium zinc telluride-based (CZT) digital detector technology are just what the nuclear cardiologist ordered to diagnose seemingly healthy patients with cardiac symptoms and to help predict their chances for an adverse event, according to a study published online April 27 in the Journal of Nuclear Medicine.
AI start-up eyes deep learning to aid imaging in China
May 8, 2017 -- An artificial intelligence (AI) start-up in China is seeking to use deep learning to help address the country's severe shortage of radiologists. The firm believes its algorithms will make radiologists more efficient by helping them read images faster and focus more attention on abnormal exams.
Ottawa Hospital slashes lung cancer treatment time
May 8, 2017 -- What's the best way to reduce time to treatment for patients with abnormal CT scans who are referred for suspected lung cancer? The radiology department at a Canadian hospital was able to cut the time to treatment in half for referred patients, according to a presentation at last month's Canadian Association of Radiologists meeting in Montreal.
Elekta debuts MR-linac radiation therapy system at ESTRO
May 8, 2017 -- Radiation oncology vendor Elekta is using this week's annual meeting of the European Society for Radiotherapy and Oncology (ESTRO) to launch Elekta Unity, the company's MRI-guided radiation therapy system.
Nuclear cardiology lab cuts radiation dose by 60%
May 8, 2017 -- A large nuclear cardiology lab was able to reduce its average radiation dose by 60% over the past eight years, according to new research presented on Friday at the International Conference on Nuclear Cardiology and Cardiac CT in Vienna and published in JACC: Cardiovascular Imaging.
Varian launches Halcyon radiation therapy unit at ESTRO
May 6, 2017 -- Taking inspiration from diagnostic radiology, radiation oncology firm Varian Medical Systems is launching its new Halcyon platform for radiation therapy at the European Society for Radiotherapy and Oncology (ESTRO) in Vienna.

MRI detects cause of vision problems in astronauts
May 5, 2017 -- MRI scans of astronauts who spent time at the International Space Station confirm that increased orbital and ventricular cerebrospinal fluids cause vision problems that worsen with extended time in space and linger after the travelers have returned to Earth.
Diagnostic reference levels reduce CT doses
May 5, 2017 -- Establishing diagnostic reference levels (DRLs) for radiation dose is a powerful tool for reducing radiation exposure in CT, according to a study by Canadian researchers published in the May issue of the American Journal of Roentgenology.
