Magnetic resonance and diffusion tensor imaging of the adolescent rabbit growth plate of the knee
Magnetic Resonance in Medicine, Volume 89, Issue 1, Page 331-342, January 2023., 2023 Purpose To assess the ability of MRI‐DTI to evaluate growth plate morphology and activity compared with that of histomorphometry and micro‐CT in rabbits. Methods The hind limbs of female rabbits aged 16, 20, and 24 wk (n = 4 per age group) were studied using a 9.4T MRI scanner with a multi‐gradient echo 3D sequence and DTI in 14 directions (b‐value ...

Geofluids, Volume 2022, Issue 1, 2022., 2022 The embedded discrete fracture model (EDFM) has been popular for the modeling of fractured reservoirs due to its flexibility and efficiency while maintaining the complex geometry of fracture networks. Though the EDFM has been validated for single‐phase flow simulations, some recent cases show that the EDFM might result in apparent errors in multiphase ...
