Dual energy scans can also prove useful in diagnosing gout in an acute care setting. Pain in the afflicted joint could be a symptom of any number of conditions, but if gout is suspected, spectral CT can be used to reveal deposits of monosodium urate crystals (MSU) around the joint.

However, when evaluating gout patients, DECT frequently colour-codes material not truly representing MSU crystals and this might lead to misinterpretations. The characteristics of and variations in properties of colour 2020-11-23 · Dual-energy CT (DECT) is a state-of-the-art technology that simultaneously processes data from multiple photon energies in a single CT acquisition. The principle of dual energy dates back to the 1970s, whereas the first clinical DECT scanner was available in 2006. Dual Energy CT 1.

Dual Energy Subtraction is available on the Discovery 656HD and the Optima 646HD fixed x-ray systems. GSI has the exciting potential to be used as a routine scan acquisition mode offering additional anatomical and functional information to help expedite and assist in an accurate CT diagnosis. Gemstone Spectral Imaging (GSI) is a novel dual energy application that uses rapid kV switching to acquire the dual energy samples almost simultaneously to generate material density data that can be used for the separation of materials and derivation of monochromatic spectral images using a projection Although the results of initial studies indicated that dual-energy CT produced higher radiation doses than did single-energy CT , many subsequent clinical studies of dual-source dual-energy CT have shown that dual-energy CT exposes patients to radiation doses similar to those received during conventional single-energy CT (38,39). The results of more recent studies of dual-energy CT performed with fast kilovoltage switching also have shown radiation dose levels similar to those with Dual Source Dual Energy Scanning Faster image acquisition Improved temporal resolution (83ms) for cardiac imaging Higher power (160kW) Both tubes at different kVp Improved image quality In Obese patients 500 lbs (220kg) Tissue material Differentiation 80 140 120 120 Principle of Dual Energy CT – Image Based Evaluation Each material is characterized by its „Dual Energy Index “ x80 and x 140 are the Hounsfield numbers at 80 kV and 140 kV, resp .
