RE: relative enhancement; ME: maximum enhancement; TTP: time to peak; BE: brevity of enhancement; Ds: pure diffusion coefficient; : perfusion fraction; Df: pseudo-diffusion coefficient. Values are presented as 95% limits of agreement (LoA, limits of agreement; mean interdevice difference; spans of limits of agreement). |
