GE Healthcare’s Gemstone Spectral Imaging Emerging as a “Must Have” Diagnostic Tool

Thousands of patients worldwide benefiting from GSI’s improved diagnostic confidence

WAUKESHA, Wisconsin--(BUSINESS WIRE)-- Affirming its commitment to high quality patient care, GE Healthcare today spotlighted the increased clinical adoption and emergence as a ”must have” tool of its Gemstone Spectral Imaging* (GSI) Computed Tomography (CT) application at the 2011 International Symposium on Multidetector Row CT in San Francisco. GE’s dual-energy GSI technology represents a new standard of visualization that helps address two main CT clinical imaging challenges: material separation and artifact reduction.

Responding to customer demand, GE Healthcare’s industry-leading second release of GSI technology now includes refinements in image quality and usability. This second release is being provided to all current GE Discovery CT750 HD systems with GSI worldwide to help clinicians make well-informed, patient-focused decisions.

“Spectral CT is now a part of our routine clinical practice, particularly for cases with known metal implants,” said Lawrence Tanenbaum, MD, FACR, Director of MRI and CT at Mount Sinai School of Medicine in New York. “Healthcare professionals in general, radiologists in particular, and patients, most importantly, benefit as spectral imaging's enhanced and enriched information continues to become adopted around the world.”

GSI helps clinicians make efficient, confident diagnoses by more clearly characterizing lesion attributes, removing or reducing artifacts, and enhancing areas of medical interest – all in a single exam.

Specifically, GSI aids clinicians in determining the precise size and nature of lesions, and whether they are enhancing. In a First Place Paper recently awarded by the The Society of Uroradiology, Dr. Amy Hara and others from the Mayo Clinic in Arizona demonstrated improved renal lesion enhancement using GSI, concluding that it contributes to diagnostic accuracy and confidence when assessing renal lesion enhancement compared to using routine CT or monochromatic images alone.

Since CT’s inception, clinicians’ view of anatomy has been limited by potential artifacts and the inability to distinguish between different materials of the same density. For example, metal implants often generate artifacts while materials like iodine and calcium are difficult to differentiate. Utilizing two different energy levels to separate and quantify materials like calcium, iodine and water, GSI-enhanced images offer significant artifact reduction and improved clarity to help healthcare professionals overcome these challenges.

“GSI is pioneering a new generation of dual energy CT imaging,” said Steve Gray, Vice President and General Manager of CT & Advantage Workstation for GE Healthcare. “By helping clinicians increase their diagnostic confidence and accuracy through GSI, we’re helping them better serve their patients’ needs.”

GSI was developed in conjunction with leading institutions including Mayo Clinic, Massachusetts General Hospital, Hong Kong Sanatorium & Hospital, and Japan’s Keio University.
