syngo.CT Single Source Dual Energy is designed to operate with CT images which have been acquired with Siemens Single Source scanners. The various materials of an anatomical region of interest have different attenuation coefficients, which depend on the used energy. These differences provide information on the chemical composition of the scanned body materials. syngo.CT Single Source Dual Energy combines images acquired with low and high energy spectra to visualize this information. Depending on the region of interest, contrast agents may be used.
The functionality of the syngo.CT Single Source Dual Energy applications is as follows:
• Monoenergetic
• Gout Evaluation
• Brain Hemorrhage
• Liver VNC
• Monoenergetic Plus
• Bone Marrow
• Kidney Stones*)
*) Kidney Stones is designed to support the visualization of the chemical composition of kidney stones and especially the differentiation between uric acid and non-uric acid stones. For full identification of the kidney stone additional clinical information should be considered such as patient history and urine testing. Only a well-trained radiologist can make the final diagnosis under consideration of all available information. The accuracy of identification is decreased in obese patients.
Indications for use as stated in the FDA summary.
