National Oncologic PET Registry takes initial enrollment steps
An RSNA attendee registers for the National Oncologic PET Registry (NOPR), which began accepting preregistration at the Chicago meeting.
The registry is part of a compromise agreement between PET imaging proponents and the Centers for Medicare and Medicaid to enable Medicare to expand coverage to most PET cancer imaging procedures. The only such procedures excluded from coverage are initial breast cancer diagnosis, breast cancer initial staging to evaluate axillary lymph nodes, and melanoma staging to evaluate regional lymph nodes.
Although formal registration will commence at a later date, preregistration will get facilities started on the process, said Dr. Barry Siegel, cochair of the NOPR working group.
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.
