The latest version of virtual endoscopy, Endo 3D-unfolded, has entered the marketplace. Philips Medical Systems has introduced the software feature as part of its multimodality image processing workstation, EasyVision 5.2. The product transforms abdominal CT and MR images into a series of unfolded views, providing the physician with an omnidirectional visualization of the inside of the colon. Included are views of the backside of folds and inner aspects of curves that may be difficult to see using conventional endoscopy. The reconstruction allows a virtual inspection of 99.5% of the colon walls, according to the company, to assist in the visualization of polyps and abnormal lesions. Any suspicious area can be immediately verified in original CT or MR images. The company claims the "unfolded" method is more time-efficient for navigation and inspection than conventional 3D display methods, reducing the average time needed to interpret the prone and supine data from 35 minutes to fewer than 20 per patient.
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.
