Research Summary

Dr. Barker’s funded research projects include the development of techniques for proton magnetic resonance spectroscopic imaging (MRSI) for the diagnosis of breast cancer, and the investigation of brain metabolism in Neurofibromatosis Type-1 (NF1). MRSI may play a role in understanding the causes of NF1-associated cognitive impairment, as well as in the diagnosis of brain lesions in patients with NF1. 

 

A major goal of Dr Barker’s research group is to provide state-of-the-art magnetic resonance imaging (MRI) and MRSI data acquisition and image processing technology, and unique MRI expertise, to facilitate the biomedical research of NIH-funded neuroscientists at institutions throughout Maryland and the United States.
