Flowchart for case selection. After selecting 348 patients with the diseases included in the study from mPower (Nuance Communications, Burlington, Mass) searches, chart reviews were performed to confirm the diagnoses. The first diagnostic MRI scan was chosen, and then the final cases were selected by excluding cases with inadequate imaging (eg, missing sequences or excessive motion), multiple diagnoses, or imaging findings outside deep gray matter. The final sample (n = 212) was then randomized into training cases (n = 110) and test cases (n = 102) by randomly selecting two to three cases of each diagnostic entity and 10 normal cases to the test cases. The remainder of the cases became training cases. FLAIR = fluid-attenuated inversion recovery, IRB = institutional review board.
