MR spectroscopy moves from the brain to bones
Characterizing musculoskeletal tumors with MR spectroscopy could eliminate the need for standard imaging and histological staging. Researchers at Johns Hopkins University have found preliminary success using MRS at 3T to diagnose bone tumors.
Characterizing musculoskeletal tumors with MR spectroscopy could eliminate the need for standard imaging and histological staging. Researchers at Johns Hopkins University have found preliminary success using MRS at 3T to diagnose bone tumors.
Dr. Laura M. Fayad, an assistant professor of radiology, and colleagues examined six bone tumors. They correctly detected a choline peak in two malignant cases and no choline peak in four benign cases, Fayad told Diagnostic Imaging.
The group had previously been successful in using MRS at 1.5T to investigate resected tumors. Fayad reported that study at the 2004 RSNA meeting.
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.
