Saline-enhanced RFA meets expectations
Using saline perfusion to improve radio-frequency ablation of liver tumors is feasible and safe, but rare life-threatening complications persist, according to a study reported in the American Journal of Roentgenology.
Using saline perfusion to improve radio-frequency ablation of liver tumors is feasible and safe, but rare life-threatening complications persist, according to a study reported in the American Journal of Roentgenology.
Dr. Antonio Giorgio and colleagues at the D. Cotugno Hospital in Naples, Italy, enrolled 336 consecutive patients with liver cancer. Saline-perfused cannulated needles treated tumors with fewer major complications than the internally cooled or expandable probes. But a sudden worsening of functional liver reserve may occur with the saline regime even when only a small nodule of hepatocellular carcinoma is treated.
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.
