ow-dose MSCT sharpens pediatric lung images
A respiratory-gated, low-dose, 16-slice CT imaging technique successfully depicts the neonatal lung during continuous breathing, according to research presented at the 2004 RSNA meeting in Chicago.
A respiratory-gated, low-dose, 16-slice CT imaging technique successfully depicts the neonatal lung during continuous breathing, according to research presented at the 2004 RSNA meeting in Chicago.
Dr. Patrik Rogalla and colleagues from Charite Hospital in Berlin used 10 mAs at 120 kVp, 2 to 4.8 pitch, and 0.5-mm slices. They measured total volumes for the left and right pulmonary airways during breathing in 20 newborns and infants.
The technique allowed for in-depth examination of global lung function parameters, as well as separate analysis of both lungs and individual lobes, according to Rogalla.
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.
