Functional MR imaging detects liars and cheats
TV cops are unlikely to visit their local MR center when extracting confessions from suspected criminals. But the appearance of 3T scanners on programs such as "CSI" could simply be a matter of time, following research demonstrating the accuracy of fMRI-based lie detection.
TV cops are unlikely to visit their local MR center when extracting confessions from suspected criminals. But the appearance of 3T scanners on programs such as "CSI" could simply be a matter of time, following research demonstrating the accuracy of fMRI-based lie detection.
Group-based studies have already shown that telling the truth and lying cause different areas of the brain to light up on fMRI. Now a team from the University of Pennsylvania has shown that this neuropsychological phenomenon can be used to reveal individual liars. Their data analysis has revealed the power of fMRI to identify truthful or false statements correctly almost 90% of the time.
"For fMRI to be used in practice for lie detection, you need to be able to put a subject in a scanner, ask 20 questions, and distinguish between truth and lies without knowing which is which in advance," said Dr. Daniel Langleben, an assistant professor of psychiatry at Penn. "That is what we have done."
Full details of the investigation will be published in Human Brain Mapping and NeuroImage.
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.
