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
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.
AI Mammography Platform Shows Promising Results for Detecting Subclinical Breast Cancer
October 3rd 2024Mean artificial intelligence (AI) scoring for breasts developing cancer was double that of contralateral breasts at initial biennial screening and was 16 times higher at the third biennial screening, according to a study involving over 116,000 women with no prior history of breast cancer.
