Interventional radiologists in Italy have shown the feasibility of concurrent radio-frequency ablation of hepatic and pulmonary tumors.
Interventional radiologists in Italy have shown the feasibility of concurrent radio-frequency ablation of hepatic and pulmonary tumors.
Dr. Davide Becanni and colleagues at the University of Florence performed 65 RF ablations in 25 patients with hepatic and pulmonary metastases from colorectal carcinoma. Both hepatic and pulmonary lesions were treated in a single-session procedure using one RF generator with either single or cluster probes. RFA successfully ablated all lesions, as confirmed by either CT or PET follow-up.
No liver complications were reported, although five patients who were treated for pulmonary metastases developed pneumothorax.
Physicians still have to define the best target population and the cost-benefit ratio for dual RFA. But his study shows that the procedure can reduce hospitalization time without adding to the complication rate, Becanni said.
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.
