Dr. Brewington’s research interests include clinically applicable lung cancer research. Currently,  she is involved in ongoing research on CT lung perfusion and lung density research. Past projects included chest imaging for CT cancer imaging and pulmonary fibrosis and dose lowering accuracy research in low dose CT lung screening.  Aspects of her findings have been presented in several national conferences, including Radiological Society of North America, Society of Thoracic Radiology (where she won the Jack Westcott award), and  more recently the 2018 MD Anderson Cancer clinic (where she won the Thoracic malignancy research award). During her career, she has served as co-investigator of various pulmonary funded research projects. Currently she is the PI-investigator on a funded clinical trial involving pulmonary CT in which she studies the use of CT perfusion as a potential cancer biomarker.
