Intravascular ultrasound developer EndoSonics has received Food and Drug Administration clearance for its disposable pull back device, Trak Back. The device allows users to control EndoSonics intravascular ultrasound (IVUS) imaging catheters, thus facilitating both 3-D-like images and cross-sectional displays. Trak Back was designed for use with EndoSonicss Oracle ultrasound systems and Visions Five-64 series of ultrasound catheters.
The device is automated, which the Rancho Cordova, CA, company believes will make it easier to use than competitive IVUS products that are mechanical. Trak Back is part of EndoSonicss strategy to provide its customers with IVUS-guided stenting products by combining its catheters with therapeutic devices. EndoSonics expects to begin shipping Trak Back by the end of the third quarter 1999.
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.
