TherVoyant technologies were featured in two abstracts presented at the 2017 Annual Meeting of the International Society of Magnetic Resonance in Medicine (ISMRM), hosted in Honolulu, Hawai`i, USA. The first, titled “Controlling brain infusion distributions: Moving from surgical planning to real-time MR Guidance”, was a poster presentation, while Miles Olsen…
Controlling brain infusion distributions: Moving from surgical planning to real-time MR Guidance
Abstract: The hetergeneity of the brain makes designing a desired end drug distribution through pressurized catheters difficult. We present a method to utilize real-time MR monitoring of a co-infused Gd tracer during initial stages of the infusion to derive a real-time 3D estimate of the velocity front. We also describe…
Targeted delivery of stem cells to the brain using real-time interventional MRI
Abstract: We present an intraoperative MRI protocol for stereotaxic surgery to precisely deliver induced pluripotent stem cells to targeted locations within the brain of a non-human primate model. Previously, these surgeries were performed in stereotaxic operating rooms with no intraoperative imaging, or in a conventional MRI system without real-time guidance.…
Real-Time Intraoperative MRI Intracerebral Delivery of Induced Pluripotent Stem Cell-Derived Neurons.
Abstract: Induced pluripotent stem cell (iPSC)-derived neurons represent an opportunity for cell replacement strategies for neurodegenerative disorders such as Parkinson’s disease (PD). Improvement in cell graft targeting, distribution, and density can be key for disease modification. We have previously developed a trajectory guide system for real-time intraoperative magnetic resonance imaging…
Overexpressing corticotrophin releasing hormone (CRH) in primate amygdala increases anxious temperament and alters its neural circuit.
Abstract: BACKGROUND: Nonhuman primate models are critical for understanding mechanisms underlying human psychopathology. We established a nonhuman primate model of anxious temperament (AT) for studying the early-life risk to develop anxiety and depression. Studies have identified the central nucleus of the amygdala (Ce) as an essential component of AT’s neural…
