Advanced magnetic resonance (MR) techniques in neuroimaging
- brainstem and cervical spinal cord MRI at ultra-high field.
- functional and structural assessment of the spinal cord and optic nerve.
- functional MRI of small nuclei in the brain, such as the habenula.
Neuroimmunology of Anhedonia in Adult Major Depressive Disorder
The purpose of this study is to find out if inflammation in the body and brain are related to feelings of loss of pleasure. Loss of pleasure can be easily measured and is related to specific linked brain regions. Our laboratory and others have shown that inflammation measured in ...
Neurophysiological biomarkers for personalized spinal cord injury rehabilitation
The purpose of this study is to better understand how patients' ability to move and feel after spinal cord injury (SCI) relates to the results of their brain and spinal cord magnetic resonance imaging (MRI) after spinal cord injury. The research MRI examination in this study take...
Imaging optic nerve function and pathology
The purpose of this magnetic resonance imaging (MRI) study is to take clear pictures of a patient's optic nerve to see how they are affected by glaucoma. We will take high-resolution pictures of the optic nerve using MRI to evaluate how patients see through their eyes. We will de...

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr.Xu did not report having any of the following types of financial relationships with industry during 2016 and/or 2017: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
