CT radiation dose falls over time, but still varies widely
April 4, 2017 -- CT radiation dose dropped a little over the course of a large seven-year study of patients undergoing repeat scans. But just as noteworthy were large variations in dose for repeat procedures in the same patients over time, researchers concluded in a paper published March 28 in the American Journal of Roentgenology.
Machine learning could reduce inappropriate knee MRI scans
April 3, 2017 -- Supported by machine-learning technology, researchers have developed a natural language processing algorithm that successfully automates classification of MRI knee scans to better understand MRI utilization, according to a study in the April issue of the American Journal of Roentgenology.
What's next for U.S. healthcare regulation?
April 3, 2017 -- Now that the first attempt at repealing the Affordable Care Act has fallen short, what can we expect next from the U.S. government on healthcare reform? Cynthia Moran of the American College of Radiology offers some thoughts.
ACS: U.S. cancer death rates continue to fall
March 31, 2017 -- Overall cancer death rates continued to decline from 2010 to 2014, the latest period examined in the American Cancer Society's (ACS) annual report on cancer, the ACS said in a statement accompanying a report in the Journal of the National Cancer Institute.
Spectral Doppler metric spots hepatic arterial stenosis
March 31, 2017 -- A new quantitative spectral Doppler ultrasound measurement can accurately detect liver transplant hepatic arterial stenosis, offering the potential of reducing the number of unnecessary angiography procedures in these patients, according to research published in the April issue of the Journal of Ultrasound in Medicine.
Role of imaging modalities is changing for PE diagnosis
March 31, 2017 -- The use of ventilation/perfusion SPECT scans to rule out pulmonary embolism (PE) is evolving. What used to be the definitive test for PE is shifting into a role that harmonizes with the use of pulmonary CT angiography, according to an article in the American Journal of Roentgenology.
How accurate are DCIS predictions from radiologists?
March 30, 2017 -- Radiologists can predict the presence of invasive cancer with fairly high accuracy, but their accuracy dips when it comes to predicting ductal carcinoma in situ (DCIS), according to a study published in the April issue of the American Journal of Roentgenology.
#MyRadGirlfriend No. 32: Customer-focused imaging?
March 30, 2017 -- There's no doubt that radiology is changing, but not all of those changes are for the better. Andy finds that some of the recent changes in her department are a bit hard to swallow in the next installment of #MyRadGirlfriend.
AIUM: Is MRI really needed after MSK ultrasound?
March 29, 2017 -- ORLANDO, FL - MRI exams performed after an initial musculoskeletal (MSK) ultrasound study are nearly always concordant with ultrasound results and rarely change clinical management, according to a Tuesday presentation at the American Institute of Ultrasound in Medicine (AIUM) conference.
AIUM: Machine learning may aid breast ultrasound reads
March 28, 2017 -- ORLANDO, FL - After analyzing quantitative information from breast ultrasound exams, machine-learning technology can achieve high sensitivity and specificity for breast cancer, according to research presented on Monday at the American Institute of Ultrasound in Medicine (AIUM) meeting.
