A 20-year-old female patient who was clinically diagnosed to be smart phone dependent, underwent clinical psychiatric evaluation according to SAS-SV that was 35. Axial directionally encoded color map (A) indicates directions of fiber tracts of left external capsule (EX) represented by green color, means; antero-posterior direction. Axial FA map (B) reveals focal decrease in the FA value in the left external capsule measures = 0.39 (white arrow). Axial MD map (C) reveals a focal increase in the MD value in the left external capsule measures = 1.19 × 10–3 mm2/s, (white arrow), denoting early white matter changes in it, which is highly significant for smart phone dependency. Axial directionally encoded color map (D) indicates the directions of fiber tracts of left superior longitudinal fasciculus (SLF) presented with green color that means it is antero-posterior in direction. Axial FA map (E) reveals a focal decrease in the FA value in the left superior longitudinal fasciculus measures = 0.3 (white arrow). Axial MD map (F) reveals a focal increase in the MD value in the left superior longitudinal fasciculus measures = 0.85 × 10–3 mm2/s (white arrow), denoting early white matter changes in it
