AB  - PURPOSE: We studied imaging parameters for the three-dimensional phase-sensitive 
      inversion recovery by a late gadolinium enhancement (3D PSIR) method. METHOD: In 
      the 3D PSIR method using a 1.5 Tesla MRI system and a polyvinyl alcohol (PVA) gel 
      phantom, we evaluated the relation of the signal intensity at multiple inversion 
      times (TI), 100-500 ms; flip angles (FA), 15-35 degrees ; and segments, 20-45. In 30 
      patients with chronic myocardial infarction, we measured and compared the late 
      gadolinium enhancement (LGE) image area of ratio for each of 3 sections on both 
      3D LGE images by a non-breath hold and two-dimensional inversion recovery (2D IR) 
      method non-breath hold. RESULT: In the 3D PSIR method, we recognized the signal 
      intensity to make the width of step, maximum, and we recognized that the TI 
      range, to keep the effective signal intensity difference constant, was limited on 
      each phantom. The more this TI range decreased the bigger the difference in the 
      FA and signal intensity. The set-up range of TI for the segment number remained 
      the same. In the clinical setting, we recognized a good correlation between the 
      3D PSIR method (TI 300 ms, FA 20 degrees ) and the IR method (r=0.905, p<0.001). The 
      imaging parameter that can be used in the clinical setting with the 3D PSIR 
      method is FA 20 degrees  TI 200-300 ms, with the segment number adjusted by the cardiac 
      cycle.
