Four Varian MRI scanners will be installed next year at the University of California, San Diego Center for Functional MRI and the Salk Institute for Biological Studies at UCSD. The scanners will be used for an extensive range of functional MRI research.
Researchers at the university and the Salk Institute are using very high field magnets rated from 3 to 7 tesla to study both humans and animals. By contrast, conventional MRI scanners usually have field strengths only up to 1.5 telsa. Very high field MR machines are employed for research because they are more sensitive and produce better images of brain function and other physiology. These systems will be applied to identification of specific chemicals in the brain and other organs.
UCSD has ordered 3- and 4-tesla full-body imaging systems for basic functional research in visual, cognitive, auditory, and developmental neuroscience. The 4.7-tesla system will be used to map brain activity in primates, as well as for cardiovascular and pulmonary imaging. The 7-tesla rodent imaging system will be used for cardiovascular studies in genetically altered strains of mice.
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.
