Imaging scientists back MR to detect ductal carcinoma
MRI, possibly employing higher field strengths and dedicated breast coils, should be used more often for detecting ductal carcinoma in situ, according to a panel convened by the National Institutes of Health.
MRI, possibly employing higher field strengths and dedicated breast coils, should be used more often for detecting ductal carcinoma in situ, according to a panel convened by the National Institutes of Health.
MRI is used for adjunct screening in women at high risk, but could gain significance when diagnosing DCIS, according to a Sept. 24 statement issued by the panel. The experts recommended looking at how higher field strength magnets and dedicated breast coils might improve detection. They also called for comparative effectiveness studies in individuals who do and do not undergo MRI. The comments came in a conference sponsored by the NIH and the National Cancer Institute.
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.
