GBCAs for cardiac MRI carry low allergic reaction risk
October 29, 2020 -- Using gadolinium-based contrast agents (GBCAs) for cardiac MRI carries a risk of less than 1% for allergic reactions -- although macrocyclic GBCAs do appear to be safer than linear ones, according to a study published October 29 in Radiology: Cardiothoracic Imaging.  Discuss
CTA spots COVID-19 in stroke patients
October 29, 2020 -- Scanning acute ischemic stroke patients with CT angiography (CTA) helps determine if they have COVID-19 faster than waiting for results from a nasal swab, say researchers in a study published October 29 in Stroke. The findings add to the debate over the best time to use CT during COVID-19.  Discuss

Use F-18 fluciclovine PET/MRI to stage prostate cancer
October 28, 2020 -- PET/MRI with the F-18 fluciclovine radiotracer shows promise for initial staging of high-risk prostate cancer and for evaluating response to androgen deprivation therapy, according to a pilot study published online October 14 in the American Journal of Roentgenology.  Discuss
PSMA-PET reveals new salivary glands
October 28, 2020 -- Imaging with the use of prostate-specific membrane antigen (PSMA) has led to the discovery of a pair of salivary glands, found tucked away inside the skull where the nasal cavity and throat meet. The findings were published recently in Radiotherapy & Oncology.  Discuss
PET with Axumin boosts prostate cancer outcomes
October 27, 2020 -- Patients with recurrent prostate cancer had better outcomes when PET with the Axumin radiopharmaceutical was part of the imaging package guiding their radiation therapy, according to a study presented on October 26 at the American Society for Radiation Oncology annual meeting.  Discuss
Should genetic testing for breast cancer stop at 65?
October 27, 2020 -- Genetics still play a crucial role in whether women over the age of 65 develop breast cancer, according to new research to be presented at the American Society of Human Genetics 2020 meeting, taking place virtually October 27-30.  Discuss
New calculator assesses cognitive decline on brain MRI
October 27, 2020 -- A new artificial intelligence (AI) calculator for analyzing brain tissue damage derived from MRI scans can detect with 70% accuracy early signs of cognitive decline, according to a study published October 27 in Academic Radiology.  Discuss
