NIH R01-HL122754 (PI: Felix W. Wehrli, Ph.D.)

Neurometabolic Assessment of Obstructive Sleep Apnea by MRI
To test the hypothesis that patients with obstructive sleep apnea have abnormal neurometabolism and impaired neurovascular reactivity and that treatment with continuous positive airway pressure partially reverses these conditions.

NIH R01-AR055647 (PI: Felix W. Wehrli, Ph.D.)

Osteoporosis Treatment Response Assessed by Micromechanical Modeling of MRI Data.

To evaluate changes in bone mechanical competence in early postmenopausal women undergoing mechanical stimulation via image-based computational biomechanics.

NIH R01-HL109545 (PI: Felix W. Wehrli, Ph.D.)

MRI Assessment of Vascular Reactivity

To develop and translate to the clinic novel imaging methodology that enable diagnosis of the earliest stages of disease thereby allowing for lifestyle changes and early intervention in subjects at risk.

NIH R01-AG038693 (PI: Felix W. Wehrli, Ph.D.)

MRI-Based Assessment of Structural and Mechanical Implications of Osteoporosis

To address the hypothesis that bone mechanical competence can be predicted on the basis of high-resolution MRI in human cadaver specimens comparing mechanical test results with computational biomechanics and apply the methodology to postmenopausal women at risk of fracture by comparing the structural and mechanical parameters with vertebral deformity status.


NIH R21-NS082953 (PI: Felix W. Wehrli, Ph.D.)
Feasibility of Direct Quantitative Magnetic Resonance Imaging of Myelin
To develop and evaluate 3D zero-echo-time (ZTE) quantitative MRI acquisition and analysis methods involving tissue water suppression and compressed sensing reconstruction, with subsequent translation to a 3T clinical imager toward a long term goal of translation to the clinic as an alternative and possibly superior technique for regional myelin quantification in patients with myelin abnormalities and for providing means to evaluate treatment effectiveness.

NIH U01-HD087180 (PI: Nadav Schwartz, M.D, Daniel Licht, M.D.)
Developing Paradigm-Shifting Innovations for In Vivo Human Placental Assessment in Response to Environmental Influences
To develop a multi-modal approach to examining human placental structure and function in vivo and in real time. The goal is to equip clinicians and researchers with novel tools to enhance the ability to directly evaluate the placenta in a clinically meaningful manner.
