RF ablation takes on lung lesions
Already established in the liver and kidneys, radio-frequency ablation has shown early promise as a treatment for unresectable lung tumors. One of the first studies on the technique, presented by Korean researchers in May at the American Roentgen Ray Society meeting, found high mortality from the procedure but few complications among patients who responded well. In 19 patients with unresectable lung cancer ranging from stage Ib to IV, eight patients remained alive at six months of follow-up. The research team achieved complete ablation in 30% of patients, using internally cooled RF needles delivering 150 watts for 20 to 40 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.
