Reduced contrast CT lowers cost, risk in elderly patients
Elderly patients can undergo CT scanning of the pancreatobiliary region with only 90% or less of the contrast dose required in other patients without compromising the exam's quality.
Elderly patients can undergo CT scanning of the pancreatobiliary region with only 90% or less of the contrast dose required in other patients without compromising the exam's quality. A lower dose could also reduce costs and the risk of complications.
Dr. Shigeki Itoh, a radiologist at Nagoya University School of Health Science in Japan, and colleagues assessed 112 patients who had undergone triple-phase contrast-enhanced CT exams on a 16-slice scanner for known or suspected pancreatobiliary disease. They split the patients into three groups according to age and weight (AJR 2006 Aug;187[2]:505-510).
The investigators found that after a 12.2% reduction in the volume and rate of contrast injection, they could achieve equivalent contrast enhancement in patients older than 60 as compared with patients aged 60 or younger undergoing scanning with a standard dose.
Considering Breast- and Lesion-Level Assessments with Mammography AI: What New Research Reveals
June 27th 2025While there was a decline of AUC for mammography AI software from breast-level assessments to lesion-level evaluation, the authors of a new study, involving 1,200 women, found that AI offered over a seven percent higher AUC for lesion-level interpretation in comparison to unassisted expert readers.
FDA Clears Virtually Helium-Free 1.5T MRI System from Siemens Healthineers
June 26th 2025Offering a cost- and resource-saving DryCool magnet technology, the Magnetom Flow.Ace MRI system reportedly requires 0.7 liters of liquid helium for cooling over the lifetime of the device in contrast to over 1,000 liters commonly utilized with conventional MRI platforms.
