Study bolsters case for breast MRI screening
Breast MRI is far superior to x-ray mammography for picking up ductal carcinoma in situ generally and for spotting high-grade early-stage disease, according to Dr. Christiane Kuhl and colleagues at the University of Bonn.
Breast MRI is far superior to x-ray mammography for picking up ductal carcinoma in situ generally and for spotting high-grade early-stage disease, according to Dr. Christiane Kuhl and colleagues at the University of Bonn.
They enrolled 7319 women who underwent mammography and MRI in a screening setting. Of these, 167 received both imaging tests preoperatively and had a biopsy-proven diagnosis of DCIS without associated invasive breast cancer. Mammography detected 56% and MRI detected 92% of all DCIS. MRI detected 98% of high-grade lesions compared with 52% for mammography (Lancet 2007;370:485-492).
An editorial in the same issue suggested MRI should no longer be seen as an adjunct to mammography but as a screening modality in its own right. Study authors warned against quick conclusions, however, noting that few radiologists can offer MRI with the level of expertise required for diagnostic mammography.
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.
