Keith Hulsey, Ph.D., is an Instructor in Radiology at UT Southwestern Medical Center, and a member of its Radiology Research Faculty.
Dr. Hulsey holds a bachelor's degree from Cornell University in Ithaca, New York, and a master's degree in biomedical engineering from the University of Texas at Arlington. He received his doctoral degree in radiological sciences from UT Southwestern, where he remained to receive fellowship training in analysis of magnetic resonance spectroscopy.
During his master's research, Dr. Hulsey developed an automated algorithm to quantify white matter hyperintensity (WMH) burden using FLAIR and T1 weighted images of the brain. More than 2,000 brains were analyzed, and Dr. Hulsey worked extensively with radiologists to identify and correct outliers so that the WMH quantification could be used to explore correlations with other health data. During his doctoral research, he investigated factors that impact image quality of MR diffusion weighted images (DWI) and developed an algorithm for detecting and removing corrupted data. His postdoctoral research included collecting and analyzing voxel proton magnetic resonance spectroscopy (MRS) data from metabolic profiles of animal and human brains.
After joining the faculty at UT Southwestern in 2013, Dr. Hulsey worked on a number of other projects related to DWI and MRS. He constructed numerous MR phantoms, including an IVIM flow phantom. He also investigated several approaches to fitting DWI data to various diffusion models using both the IVIM flow phantom and simulated data. His work with diffusion imaging also includes managing a clinical trial to evaluate a 31-channel breast coil combined with a custom DWI protocol designed to improve SNR to help discriminate between malignant and benign tumors. He continues to work with MRS, focusing most recently on fat quantification in the liver and pancreas.
Dr. Hulsey's work has led him to publish nearly 15 original scholarly articles in peer-reviewed journals.
