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.
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.
