Industry News: Medicsight upgrades ColonCAD
The latest version of CT colonography software from Medicsight debuted this week at ECR 2009.
The latest version of CT colonography software from Medicsight debuted this week at ECR 2009. The newly enhanced software, dubbed ColonCAD API 4.0, uses a more powerful algorithm to uncover colorectal polyps in CT data. The CE-Marked product, which will be sold through the company’s European distributors, offers increased specificity that cuts the number of false positive CAD marks per case.
Internal tests involving patient cases demonstrated that the ColonCAD API 4.0 remains as sensitive as the previous version, but displays 50% fewer false positive marks. This works out to a mean of 6.5 false marks per patient case, according to the company. Sensitivity is 85% for polyps 2mm to 50 mm; 90% for polyps 6mm to 9 mm; and 92% for polyps 10mm and larger.
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.
