Hologic showcases new Mammosite at ASTRO 2009
A version of Hologic’s partial breast irradiation device, the MammoSite ML, took center stage this week at the American Society for Therapeutic Radiology and Oncology meeting.
A version of Hologic’s partial breast irradiation device, the MammoSite ML, took center stage this week at the American Society for Therapeutic Radiology and Oncology meeting. The multi-lumen configuration, cleared by the FDA on August 27, allows oncologists to shape the radiation dose. It is the latest enhancement of the basic design, commercially launched some seven years ago. MammoSite delivers targeted radiation therapy directly to the area where cancer is most likely to recur. A full course of radiation can be delivered in just five days. The approach minimizes radiation exposure of healthy tissue surrounding the target site, minimizing side effects such as skin discoloration and scarring, burning, fatigue, and damage to surrounding organs.
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.
