Technical Aspects of DECT with Dual Layer Detectorsuisition of two spectrally distinct data sets, dual energy CT (DECT), can be achieved in a clinical setting using either a dual x-ray source system, or rapid tube potential switching with a single x-ray source. A recent innovation permitting DECT acquisition is development of a spectral CT detector,

Rapid kV Switching Dual-Energy CT Imagingn process. As such, tomographic images depict merely the differences in x-ray attenuation between different materials over the entire energy spectrum which results in suboptimal material differentiation. Dual-energy CT is a pseudo x-ray energy resolving tomographic technique, where two x-ray beams w

Cardiovascular CTA: Contrast, Concepts, Protocols. Spectral imaging and the generation of low energy monochromatic imaging and material-specific datasets may contribute in a significant reduction in iodinated contrast volume during vascular computed tomography angiographies without hampering image quality or interpretability.

Dual-Energy CT in Thoracic Imaging perfusion. Additionally, pulmonary ventilation can be assessed using inhaled contrast agents. This functional information is obtained along with the high-resolution anatomical information CT provides. Visualization of iodine uptake has also been investigated in thoracic oncologic imaging; here, it

Myocardial Perfusion by Dual Energy CTe risk of CAD, with a high diagnostic accuracy and an excellent negative predictive value. When a coronary stenosis is present, it’s hemodynamical relevance needs to be determined in order to facilitate the appropriate therapeutic decision. CCTA per se is a poor predictor of the physiologic relevanc
