FDA clears Lunar's PIXI densitometer
The Food and Drug Administration has granted 510(k) clearance to Lunar of Madison, WI, for its PIXI peripheral bone densitometer (SCAN 4/16/97). The system, designed for scanning the heel and forearm, marks Lunar's entry into the peripheral densitometry
The Food and Drug Administration has granted 510(k) clearance to Lunar of Madison, WI, for its PIXI peripheral bone densitometer (SCAN 4/16/97). The system, designed for scanning the heel and forearm, marks Lunar's entry into the peripheral densitometry segment. PIXI uses dual-energy x-ray absorptiometry and is expected to be priced in the low $30,000 range.
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.
