Caution needed with MRI of patients with metallic implants
August 13, 2020 -- The switching of gradient coil fields in MRI scans of patients with metallic hip implants can have thermal effects that imaging professionals need to look out for, according to a presentation at this week's International Society for Magnetic Resonance in Medicine virtual conference.  Discuss
Practices can 'recover wisely' from COVID-19
August 13, 2020 -- It's possible for radiology practices to "recover wisely" to pre-COVID-19 imaging volumes, according to a study published August 10 in Academic Radiology. It comes down to close monitoring of data, researchers believe.  Discuss
Follow-up SPECT/CT scan tracks radionuclide dose
August 13, 2020 -- Australian researchers have developed a technique that uses a follow-up SPECT/CT scan after radionuclide therapy to personalize the radiation dose delivered, according to a study published in the July issue of the Journal of Nuclear Medicine.  Discuss
CTA effective for detecting arterial bleeding
August 13, 2020 -- CT angiography (CTA) is an effective initial imaging exam for determining the source of bleeding in the head or neck and offers a noninvasive way to assess next steps for treatment, according to research published August 5 in Emergency Radiology.  Discuss
New technologies will drive MRI scanners of the future
August 12, 2020 -- If you could design the MRI scanner of the future, how would you do it? Tomorrow's MRI systems will use advanced coil arrays, novel sensors, new data acquisition techniques, and machine learning, according to a Tuesday plenary session of the International Society for Magnetic Resonance in Medicine virtual meeting.  Discuss
Mobile mammo leads to early detection for vulnerable women
August 12, 2020 -- A mobile mammography program in Houston led to early breast cancer detection for women at risk of forgoing regular breast screening, according to the findings of a retrospective study published on August 4 in Academic Radiology.  Discuss
Earlier breast screening shows mortality benefit
August 12, 2020 -- Starting breast cancer screening when women are in their 40s cut the risk of death by 25% at 10 years of follow-up, according to the findings of a study published August 12 in the Lancet Oncology. But the benefits of earlier screening were not statistically significant at later follow-up points.  Discuss
CNN cuts interpretation time for 4D flow cardiac MRI
August 12, 2020 -- Using a convolutional neural network (CNN) with 4D flow MRI slashes interpretation time for analyzing imaging data from pediatric patients with cardiac abnormalities, according to research delivered August 12 at the International Society for Magnetic Resonance in Medicine virtual conference.  Discuss
CMS postpones 'appropriate use' mandate past 2021
August 11, 2020 -- Clinicians ordering advanced imaging scans like CT, MRI, and PET in the Medicare system will no longer have to use appropriate use criteria (AUC) and decision support starting in 2021. On August 10, the U.S. Centers for Medicare and Medicaid Services (CMS) said it was extending the testing period for AUC through the end of 2021.  Discuss
Abbreviated MRI rivals full protocol for breast imaging
August 11, 2020 -- The diagnostic performance of abbreviated MRI was comparable to the full protocol in a systematic review presented as a virtual poster at the International Society for Magnetic Resonance in Medicine annual meeting.  Discuss
