TOF PET/MRI makes dose reduction viable for breast cancer
December 7, 2018 -- Can clinicians use as little as 10% of the conventional FDG dose and still produce diagnostic-quality images to detect breast cancer? Absolutely. It's feasible using a time-of-flight (TOF) imaging technique with PET/MRI, according to a study published in the December issue of the Journal of Nuclear Medicine.  Discuss

Beyond the black box? AI algorithm explains decisions
December 5, 2018 -- Yale University researchers have developed an artificial intelligence (AI) algorithm for classifying liver lesions on MRI scans that explains the reason for its decisions. The algorithm could address concerns about the "black box" nature of AI, according to research presented at last week's RSNA 2018 meeting.  Discuss
NIH wraps up enrollment for adolescent brain study

Motion correction technique aids PET thoracic imaging
December 5, 2018 -- To combat poor image results from patient motion in cardiac PET scans, researchers from the U.S. and U.K. have developed an automated retrospective image reconstruction method that greatly reduces the unwanted effects, according to a study published online November 15 in the Journal of Nuclear Medicine.  Discuss
Ultrasound after DBT obviates diagnostic 2D mammo
December 5, 2018 -- Performing a diagnostic mammogram to assess suspicious masses found on digital breast tomosynthesis (DBT) may not be necessary if ultrasound is available, according to a new study published online on November 29 in the British Journal of Radiology. Researchers found that ultrasound is 98% effective for further assessing masses found on DBT screening exams.  Discuss
