Non-Invasive Bacterial Identification for Acute Otitis Media using Raman Spectroscopy

Vanderbilt researchers have developed an optical-based method for real-time characterization of middle ear fluid in order to diagnose acute otitis media, also knows as a middle ear infection. The present technique allows for quick detection and identification of bacteria and can also be applied to other biological fluids in vivo.

Non-Invasive Cell Size Detection

Vanderbilt researchers have developed a new method for using contrast enhanced MRI to non-invasively map and quantify cell size on a voxel-by-voxel basis. Using this approach, it is possible to monitor and detect diseases or treatments that alter the distribution of cell sizes such as cancer, muscular dystrophy, hepatocellular hypertrophy, and hypertrophic cardiomyopathy.

Parahydrogen-Induced Polarizer (PHIP)

The present invention provides a PANACEA (Pneumatics Allow Nonmagnetic Actuation for Creation of Enhanced Alignment) polarizer system. This is an integrated assembly of pneumatically actuated, nonmagnetic hydraulic circuits that enable PASADENA chemicals to be efficiently stored, mixed, and reacted in close proximity or within NMR magnetic fields.

Real-time Detection of Position and Orientation of Wireless Endoscopy Capsule using Magnetic coupling

Vanderbilt researchers have developed a new system to detect the position, orientation, and pressure exerted on surrounding tissues of a wireless capsule endoscopy device.  Magnetic coupling is one of the few physical phenomena capable of transmitting actuation forces across a physical barrier.  Magnetic manipulation has the potential to make surgery less invasive, by allowing untethered miniature devices to enter the body through natural orifices or tiny incisions, and then maneuver with minimal disruption to healthy tissue.  In order to accomplish this goal, the pose (position and orientation) of the medical device must be available in real time.

Relaxation Time Discriminated 1H NMR for Bone Mechanical/Fracture Property Diagnostics

Advances in modern MRI pulse sequences, including ultrashort-echo time and related MRI methods for imaging short T2 signals, have enabled clinically-practical cortical bone imaging. Researchers at the Vanderbilt University Institute of Imaging Science have developed a method of distinguishing and quantifying nuclear magnetic resonance (NMR) signals for cortical bone analysis.

Selective Size Imaging using Filters via Diffusion Times (SSIFT)

Vanderbilt researchers have developed a novel MRI-based method for fast, robust, and accurate imaging of biological tissue by selecting a specific cell size range (such as tumors) without the need for a contrast agent. One exciting application of this method is imaging brain metastases (BM) that are difficult to differentiate from other brain abnormalities such as radionecrosis when using existing approaches.

pECHO: Easy to Use Smartphone App for Assisting in Transesophageal Echocardiography Exam

Transesophageal echocardiography (TEE) is a test that uses high-frequency sound waves to create images of the heart. It provides more detail that a standard echocardiogram. Vanderbilt researchers have created a software that creates an easy to follow, step-by-step procedure for a transesophageal echocardiography exam.

PANORAMIC: Precession and Nutation for Observing Rotation at Multiple Intervals about the Carrier

Methods of hyperpolarization based on parahydrogen have been expanding recently from the early applications in hydrogenation chemistry to biomedical imaging where they are expected to yield similar information as the competing technology, dynamic nuclear polarization, (DNP). These hyperpolarization experiments have already enabled the measurement of metabolism in vivo at temporal resolutions of seconds. When infused into organisms harboring tumor cells, molecules such as pyruvate and lactate have been shown to be sufficiently long-lived to infiltrate cellular metabolic cycles and be converted at different rates in cancer versus normal tissue. DNP has been used most frequently in these early studies, owing to commercial availability and the flexibility to polarize small molecules such as pyruvate and lactate. Techniques based on chemical addition or exchange of parahydrogen have also shown promise for generating metabolic contrast in vivo at similar levels of signal enhancement and at lower costs.

Simultaneous RNA and Gene Expression Profiling Using Mass Spectrometry

This technology allows the simultaneous detection of RNA transcript abundance (as an assay of gene expression) and protein abundance (as an assay of protein expression) from biological samples without RNA isolation, labeling or amplification. Existing technologies allow for very efficient determinations of protein abundance from a wide variety of biological samples. These methods are in widespread use and are based on mass spectrometry technologies. There are no available technologies that allow efficient and quantitative assessment of multiple RNA transcripts without a previous isolation followed by labeling and/or amplification. The most efficient technologies currently available make use of DNA microarrays to profile RNA abundance as a measure of gene expression. While very robust and useful, these technologies are very labor intensive and suffer from a number of technological drawbacks. This technology takes advantage of a number of existing methods and techniques and brings them together in a novel manner that greatly expands the state of the art for gene expression.
