It is difficult to identify IgA nephropathy (IgAN) and Henoch Schonlein purpura nephritis (HSPN) due to their similar image features on conversional MR anatomic images. Arterial spin labeling (ASL) and mDIXON-Quant MR imaging can provide more data about perfusion and relaxation time to evaluate the functional state of kidney. In this study, we explore to different IgAN from HSPN in pediatric patients with nephropathy using ASL and mDIXON-Quant MR sequences, and hope to improve accuracy in differential diagnosis of IgAN and HSPN.
