Varian announced that it is selling a very high field MR research system to McLean Hospital of Belmont, MA, the largest psychiatric teaching hospital for Harvard Medical School, for research into human brain function associated with drug abuse and psychiatric disorders.
Very high field (4-tesla) systems such as this one cost from $3 million to $4 million and are used only in research applications. In addition to its imaging capabilities, the Varian system can be used for in vivo nuclear MR spectroscopy, a technique for determining structural and functional relationships of chemical compounds in the brain.
Systems have also been ordered by the University of California, Berkeley; Emory University in Atlanta; and the National Institute for Environmental Studies in Tsukuba, Japan.
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.
