Echo Medical Systems is a Houston-based company that develops, manufactures, and markets NMR-MRI and CT-based whole body composition and tissue characterization equipment for use by metabolic research laboratories, the pharmaceutical industry and hospitals, and other medical facilities. Echo's class-defining EchoMRI™ technology is unique: it facilitates low-cost, rapid, highly precise, in-vivo measurements of humans and animals without anesthesia or sedation.

The EchoMRI™ proprietary method for tissue characterization provides measurements of whole body composition parameters: fat mass, lean tissue mass, free water, and total body water. The data obtained by EchoMRI™ are highly correlated to those obtained by DEXA, but the measurement procedure is faster and does not require anesthesia. In fact, the measurement duration is about 1 minute for mice and rats and about 3 minutes for humans.

Today, many EchoMRI™ and LaTheta™ systems are successfully used by more than 45 pharmaceutical companies and many leading research universities in the US, Canada, Europe, and Asia for preclinical obesity research in live animals. As drug development progresses from animal studies to human trials, there has been growing demand from Echo customers to apply EchoMRI™ in clinical trials for adult humans. As a result, Echo has developed a new EchoMRI™ system for adult humans, aimed at providing a solution to the pharmaceutical industry for testing the efficacy in clinical trials of anti-obesity and metabolic drugs and treatments.

Echo has a strong position in the underlying technology and methods of NMR-MRI-CT-based whole body and tissue composition analysis, and sophisticated proprietary know-how for tissue characterization applications in obesity, diabetes, nutrition research, pharmacology, osteoporosis, and cardiology. Beyond the existing applications, extensions of the technology are underway to measure additional body composition parameters.
