Abstract
A technique for computing a T2 relaxation time (RT) and for using the so computed T2 RT to provide an output which can aid in the detection of brain dysfunction including attention-deficit hyperactivity disorder (ADHD). The technique includes the step of obtaining T*1 matched axial images through a predetermined number of axial planes in a subject and obtaining one or more spin echo, echoplanar image sets, with TE incremented by a predetermined value in each consecutive image set through the same axial planes. The images are used to generate a map of T2 for each of the T*1 matched axial images and regions of interest (ROI) are identified in the matched axial images. Median pixel intensity values in the ROI are then used to compute a T2 relaxation time.
