CT, MRI mature for ped imaging
Pediatric radiologists have some anxiety about 64-slice CT protocols in children. It's easier, they say, to mistakenly raise the current because these scanners do not need to be cooled.

The 2005 RSNA meeting was the first to devote two sessions to pediatric neuroradiology. Studies reported at the meeting covered several other points:
- The emphasis to reduce radiation dose in CT scanning is counterbalanced by an increased evaluation of whole-body MR to image children.
- Pediatric chest researchers have successfully used hyperpolarized helium in children to help characterize airways. The technique should benefit those who must undergo serial scanning such as pediatric patients with cystic fibrosis.
- More research attention is being paid to use of diffusion MR to isolate and identify specific processes and to help characterize pathology in the brain.
- Use of MRI to evaluate neonates and infants is increasing.
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.
