Rads urge cautious CT use for swine flu workup
Findings of a Canadian study suggest CT might be better than the standard chest x-ray to show the extent and characterization of H1N1 flu.
Findings of a Canadian study suggest CT might be better than the standard chest x-ray to show the extent and characterization of H1N1 flu. But imaging experts caution physicians not to read too much into it.
A retrospective review of seven cases led Dr. Amr M. Ajlan and colleagues at the Vancouver General Hospital in British Columbia to conclude that CT could help the prospective diagnosis of H1N1. The study appeared online Oct. 21 in the American Journal of Roentgenology. Young children and adolescents carry the highest risk from the virus. Because of the radiation doses involved, any new large-scale application of CT scans needs to be carefully evaluated, said David J. Brenner, Ph.D., a professor of radiation biophysics at Columbia University.
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.
