Vice-Chair for Research, Chief of MRI Physics; Member in Medical Physics and Radiology

The Ricardo Otazo lab develops novel magnetic resonance imaging (MRI) techniques for cancer applications including fast imaging, motion resistant imaging, quantitative imaging of physical tissue parameters, and real-time MRI-guided radiotherapy using advances in MRI acquisition and computational models.

The lab develops novel magnetic resonance imaging (MRI) techniques to increase imaging speed, improve motion tolerance, image physical tissue parameters, and guide radiotherapy in real-time using advances in MRI acquisition (pulse sequences) and image reconstruction algorithms. Highlights include:

  • Non-Cartesian k-space acquisitions for motion-resistant and motion navigated imaging
  • Deep learning reconstruction of undersampled k-space data for fast 3D and 4D MRI
  • Real-time 4D MRI for radiotherapy guidance
  • Fast motion-resistant pediatric MRI with reduced anesthesia
  • Deep learning quantification of dynamic contrast-enhanced MRI
  • High-resolution distortion-free diffusion MRI in the body
  • Fast motion-resistant T1-rho mapping

Disclosures

Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.

MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.

Ricardo Otazo discloses the following relationships and financial interests:
