Radio-frequency ablation of unresectable hepatic and renal tumors has achieved considerable success, but the technique has not been widely tested in other organs. RFA may considerably reduce the size of advanced tumors in the mouth and throat and alleviate pain, according to a pioneering study by a New York City group.
Radio-frequency ablation of unresectable hepatic and renal tumors has achieved considerable success, but the technique has not been widely tested in other organs. RFA may considerably reduce the size of advanced tumors in the mouth and throat and alleviate pain, according to a pioneering study by a New York City group.
Researchers at Albert Einstein College of Medicine's Montefiore Medical Center treated seven tumors in six patients in a preliminary report published in the August issue of Head and Neck. Tumor size ranged from 2 to 15 cm, with masses located on the tongue, oropharynx, neck, and elsewhere. All patients reported significant pain relief. Given the tumors' locations, ultrasound wasn't nearly as useful as a laryngoscope for guiding treatment, but MR and CT identified tumors and guided planning for the procedures. Here, CT shows a peritonsillar mass. While the procedure has proved safe so far, collateral damage to surrounding tissue and cranial nerves remains a concern. Though RFA is for now a palliative measure, it could turn out to be a curative technique, the authors 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.
