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.
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
