Research leaps MR barrier

Seminal research in Europe has found that artifacts encountered at very high strength MR fields can be overcome without endangering patient safety. A study published in the September issue of the British Journal of Radiology produced submillimeter in-plane resolution of the brains of 10 healthy subjects using a fast spin-echo sequence optimized to work in a 4.7T environment.
Researchers at University College London optimized the number of echoes, the repetition time, and the time spent acquiring each echo to conform with U.K. safety guidelines (4 watts/Kg in the head) for specific absorption rate. They obtained uniform T2-weighted contrast images, despite substantial radio-frequency nonuniformity, by using a four-channel birdcage RF coil that allowed less sensitivity in the central coil region.
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.
