CT-based informed consent lags in U.S. academic centers
Teaching hospitals need to do a better job of informing patients about CT's potential benefits and risks, according to Yale researchers.
Teaching hospitals need to do a better job of informing patients about CT's potential benefits and risks, according to Yale researchers.
Radiologist Dr. Christoph I. Lee and colleagues mailed a survey to 113 members of the Society of Chairmen of Academic Radiology Departments. The survey asked if the institutions implemented informed consent guidelines for non-ER patients before those patients underwent CT exams.
The investigators found that radiology technologists are more likely than radiologists to inform patients about CT and associated risks. Although most teaching hospitals currently have guidelines for informed consent regarding CT, only about one-fourth inform patients about possible radiation risks and alternatives (AJR 2006;187[2]:282-287).
Could Ultrafast MRI Enhance Detection of Malignant Foci for Breast Cancer?
April 10th 2025In a new study involving over 120 women, nearly two-thirds of whom had a family history of breast cancer, ultrafast MRI findings revealed a 5 percent increase in malignancy risk for each second increase in the difference between lesion and background parenchymal enhancement (BPE) time to enhancement (TTE).
MRI Study Suggests Shape of White Matter Hyperintensities May Be Predictive of Cognitive Decline
April 7th 2025Emerging research demonstrated that cognitive declines in memory, executive function and processing speed domains were associated with irregular shape of periventricular/confluent white matter hyperintensities.
Can Abbreviated MRI Have an Impact in Rectal Cancer Staging?
April 4th 2025Abbreviated MRI demonstrated a 95.3 percent specificity for rectal cancer and provided strong agreement with the full MRI protocol for T staging and detection of extramural venous invasion, according to newly published research.
