Comparison of in vivo lung morphometry models from 3D multiple b‐value ³He and ¹²⁹Xe diffusion‐weighted MRI

Abstract

Within the experimental range of parameters considered here for both ³ He and ¹²⁹ Xe, the stretched exponential model-derived Lm_D is related nonlinearly to cylinder model-derived Lm, and demonstrates excellent agreement with the cylinder model-derived L_Alv .
