Contrast unavailability in U.S. harms diagnostic ultrasound
"We have so many CT and MR machines in the U.S. providing quick, easy, and efficient imaging that it's hard for ultrasound to compete, especially when it comes down to physicians' time.

"I don't think any radiologist would be happy to give a final diagnosis on metastatic disease in the liver using CT or MRI without a contrast agent. We do not have the advantage of using contrast agents with ultrasound in this country, since they have not been approved by the FDA.
"Having contrast agents readily available will help improve ultrasound's diagnostic capabilities in many ways, including bedside imaging of patients who cannot be transported. One of the AIUM's new initiatives is to work with the FDA to accelerate the approval process."

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.
