MR guidance permits more precise localization
Researchers from the University of Cologne in Germany report that real-time MR-guided wire localization of suspicious breast lesions using an open 1T scanner permits correction of the needle position during placement and reduces interventional procedure time.
Researchers from the University of Cologne in Germany report that real-time MR-guided wire localization of suspicious breast lesions using an open 1T scanner permits correction of the
needle position during placement and reduces interventional procedure time.
The study, published in Radiology, monitored needle placement in 30 women by using a dynamic balanced gradient-echo (single-shot turbo field-echo) sequence with a 0.5-second temporal resolution. The tip of the needle was clearly identified in all patients during placement. Diagnostic MR following the interventional procedure confirmed that the hook wires were placed 0 to 6 mm (mean, 3.3 mm) from the target lesions. Total procedure time ranged from 16 to 36 minutes.
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.
