Hitachi Medical Systems America of Twinsburg, OH, has received 510(k) clearance for its Airis II and Stratis II MRI scanners. Both systems feature improvements over previous Airis and Stratis models, and were introduced at last year's Radiological Society of North America meeting (SCAN Special Report 12/97). Airis II is a 0.3-tesla open-style scanner, while Stratis II is a 1.5-tesla short-bore style system.
In related news, Hitachi announced that it has shipped its 250th Airis system, a sign that the company continues to do well in the open-magnet segment. The 250th Airis was acquired by Medical Imaging & Diagnostics for an open MRI center in Schaumburg, IL.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
