Magnetic resonance imaging (MRI) is one of the most important and versatile tools in the repertoire of diagnostics and medical imaging. Vanderbilt researchers have developed a novel, geometry independent, self-decoupling radiofrequency (RF) coil design that will allow MRI machines to generate images at a faster rate and with greater image quality.

A new approach for obtaining less invasive optical measurements of the cervix has been developed that does not require the use of a speculum exam. This technology can visualize the cervix in vivo to find unique biomarkers that indicate various conditions such as preterm labor, cancer, human papillomavirus (HPV), and dysplasia.

Vanderbilt researchers have developed a system for enhancing the imaging capabilities of optical coherence tomography (OCT), a tool commonly used to monitor and treat patients with retinal disease. The image resolution of OCT, however, is intrinsically limited. Ideally, a contrast agent could be used to highlight specific parts of the retina within the image, but dye alone is largely ineffective because of the way OCT generates the image. Photothermal heating solves this problem by creating local zones of tissue expansion which can be distinctly detected by OCT. Photothermal-OCT is safe, effective, and enhances the imaging power of a tool widely used by opticians.

Researchers at Vanderbilt have developed a system to estimate prognostic metrics such as the length of a hospital stay, recovery status at discharge, and overall health at discharge, using only baseline imaging and clinical information gathered early in the hospital admission process. This system can assist with medical group operations and planning, it can help to educate families and patients regarding prognosis, and can be used to automatically stage patients for clinical trials.
