Oncologist slams breast MR with old data
For the third time in less than a year, results from a retrospective study of breast cancer cases were framed as new research, challenging the routine use of MRI as a means to improve surgical outcomes in newly diagnosed breast cancer patients.
Oncologist slams breast MR with old data
For the third time in less than a year, results from a retrospective study of breast cancer cases were framed as new research, challenging the routine use of MRI as a means to improve surgical outcomes in newly diagnosed breast cancer patients. The results, announced in press releases in September 2008, June 2009, and last week, are all the same and lead to the same conclusions: newly diagnosed breast cancer who receive a breast MRI are more likely to receive a mastectomy after their diagnosis and may face delays in starting treatment. The news hook for the first press release was the 2008 ASCO Breast Cancer Symposium; for the second, online publication of the Journal of the American College of Surgeons; for the third, actual print publication in the August edition of the Journal of the American College of Surgeons. In each, Dr. Richard J. Bleicher, a surgical oncologist and attending surgeon at Fox Chase Cancer Center in Philadelphia, is quoted extensively. Dr. Bleicher could not be immediately reached for comment.
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.
