New research, published in the Journal of Neuropsychiatry and Clinical Neurosciences, examined the use of three-dimensional brain imaging as a tool for diagnosing attention-deficit/hyperactivity disorder (ADHD) in place of typical two-dimensional scans. The researchers retrospectively analyzed the diagnosis of 427 patients, and compared the sensitivity for predicting ADHD. Their sensitivity rating was calculated based on the confidence interval of physicians regarding their “sureness” of the diagnosis, and the specificity of the brain scans.
The research found that 3D SPECT (single-photon emission computed tomography) imaging made it easier to achieve a definite ADHD diagnosis when compared to traditional 2D SPECT scans. 3D scans gave a sensitivity of 83% to predict ADHD diagnosis, while 2D scans gave a sensitivity of only 10%.
