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.

Vanderbilt researchers have designed a laser speckle imaging device to detect parathyroid gland viability during endocrine surgery, during which otherwise healthy parathyroid glands are prone to devascularization leading to long-term hypocalcemia. Currently, the surgeon must use his or her best judgement regarding the health of the parathyroid gland. This technology removes the guess work from the decision and provides a real-time assessment of the parathyroid viability.

Various widespread diseases associated with airway constriction can be combatted using airway stents. However, such stents are either prone to clogging themselves or tend to invade neighboring tissue. Vanderbilt engineers have developed a technology that avoids both of these pitfalls by combining the use of tissue-friendly silicone with active cilia for mucus clearing.

High-resolution pharyngeal manometry (HRM) provides an inexpensive and objective method for analyzing the pharynx during natural sleep and can be utilized to select candidates for certain surgical procedures for obstructive sleep apnea (OSA).
