Dr. Cha is committed to a career dedicated to patient-oriented research in the field of brain tumor imaging. She believes that non-invasive imaging technology will make important contributions to the health of patients through improving the specificity and precision of diagnosis and treatment monitoring, which will have significant impact on therapeutic decisions. The main focus of Dr. Cha’s research is to identify reliable surrogate markers of prognosis and therapeutic efficacy by quantitative MR imaging methods in patients with brain tumors. She believes that by using MR imaging techniques such perfusion MR imaging, diffusion-weighted imaging, and 3-dimensional proton magnetic resonance spectroscopic imaging, detection of changes in tumor angiogenesis, cellularity, invasion, tumor hypoxia, and metabolic burden can be accurately measured and will provide more specific information about patient’s early response to therapy in the context of tumor growth.
