In patients for whom surgery is not an option, percutaneous radio-frequency ablation offers a viable alternative for treating breast cancer metastatic disease in the liver.
In patients for whom surgery is not an option, percutaneous radio-frequency ablation offers a viable alternative for treating breast cancer metastatic disease in the liver.
Researchers from 12 centers participating in the tumor radio-frequency ablation Italian network (TRAIN) treated 102 patients with breast cancer, using the ablation technique. Under ultrasound or CT guidance, they applied RFA to tumors ranging from 0.8 to 5 cm in diameter. Results were presented at the 2004 RSNA meeting.
Using the Kaplan-Meier method, the researchers reported survival rates ranging from 95.2% at one year to 29.8% at five years. They completed RFA of tumors in 91.2% of the patients after 121 treatment sessions, and the primary effectiveness rate on a lesion-by-lesion basis was 86.9.
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.
