In recent years, Dr Wang’s research has focused on three directions: (1) new techniques of liver MRI and diffusion MRI; (2) spine degenerative diseases; (3) bone mineral density and osteoporotic fracture. He pioneered a number of liver MRI techniques such as diffusion derived vessel density (DDVD), T1rho, CEST, 3-dimenional analysis of IVIM parameters. His work on epidemiology of spine degeneration including disc space narrowing, spondylolisthesis, and osteoporotic fracture provides reference standard for East Asians, and also deepened the understanding of pathophysiology of spine degeneration. To reconcile with the lower lifetime risk of fragility fracture among East Asian populations (than those among Caucasians), he proposed new criteria for classifying densitometric osteoporosis for East Asians. He published the first radiographic osteoporotic vertebral fracture diagnosis expert consensus as the leading author, which majorly revised the earlier diagnosis criteria. Currently, he is actively exploring the clinical use of  a new imaging biomarker DDVD devised by him, with very promising results in the fields of placenta medicine and oncology. He is the principal developer of an AI-enabled automated vertebral fracture detection software (Ofeye series). He also proposed a new disease entity endplatitis short vertebrae, and a new classification for Schmorl’s node with congenital Schmorl’s node as a pseudo-Schmorl’s node.

He has published >360 papers, and his works have been cited > 14, 800 times, with H-index > 59 according to Web-of-Science (google scholar: citation > 22, 000 times, H-index > 69 ).
