Changho Choi, Ph.D., received his Bachelor of Science degree in 1987 from Korea University, South Korea. He then earned a Ph.D. from the University of Waterloo, Canada, where he used nuclear magnetic resonance for studying quantum tunneling of protons at low temperatures. Following several years of research in in-vivo MR spectroscopy (MRS), he joined the Advanced Imaging Research Center at UT Southwestern Medical Center in 2007.
Dr. Choi’s research has been focused on both technical and clinical developments of MR spectroscopy in brain tumors and neuropsychiatric disorders. MRS methodology development has been carried out to provide meaningful measurements of clinically-important hard-to-detect brain metabolites, including 2-hydroxyglutarate (2HG), citrate, GABA, glycine, glutamate and glutamine, etc. Specifically, 2HG, which is a direct consequence of IDH mutation in gliomas, appears to be an unprecedented imaging biomarker in brain tumors.
Research is going on to accomplish a fast, high-precision 2HG imaging modality, in parallel with translation of previously-developed methods into clinics. The clinical utility of 2HG, glycine and citrate in brain tumors is investigated in collaboration with neuro-oncologists. Also, several MRS studies are conducted to evaluate the alterations in metabolic profiles in neurological diseases, including schizophrenia, asthma and autism, in collaboration with psychiatrists.
