Dr. Nwawka completed her fellowship in musculoskeletal imaging at HSS after which she joined the Radiology and Imaging Department as an assistant attending radiologist. As a fellow, Dr. Nwawka participated in numerous research projects which have gone on to produce multiple publications in the radiology and orthopedic surgery literature. She continues to present her research at national and international meetings and has been invited to lecture on topics including nerve imaging musculoskeletal ultrasound and quantitative imaging techniques. Trained in all realms of musculoskeletal interventions and imaging including MRI, CT and ultrasound, Dr. Nwawka is particularly interested in nerve imaging and musculoskeletal ultrasound. She is the principal investigator of several grants awarded by the American Institute of Ultrasound in Medicine (AIUM), General Electric Healthcare (GEHC), the National Basketball Association (NBA) and the Radiological Society of North America (RSNA).

Peripheral Nerve Imaging
One of the goals of HSS is to advance the science of orthopedic surgery, rheumatology, and related disciplines for the benefit of patients. Physicians at HSS may collaborate with outside companies for education, research and medical advances. HSS supports this collaboration in order to foster medical breakthroughs; however HSS also believes that these collaborations must be disclosed.
As part of the disclosure process, this website lists physician collaborations with outside companies. The disclosures are provided by information provided by the physician and other sources and are updated regularly. Further information may be available on individual company websites.
Below are the healthcare industry relationships reported by Dr. Nwawka as of November 12, 2019.
By disclosing the collaborations of HSS physicians with industry on this website, HSS and its physicians make this information available to their patients and the public, thus creating a transparent environment for those who are interested in this information. Further, the HSS Conflicts of Interest Policy does not permit physicians to collect royalties on products developed by him/her that are used on patients at HSS.
Patients should feel free to ask their HSS physicians questions about these relationships.
