Blended images Siemens are created through a combination of the acquired low-energy 80 kVp and high-energy kVp data to simulate a standard kVp dataset.
The authors emphasize current state-of-the-art uses of computed tomography, but also examine emerging developments at the horizon.
This book fills and immense need"-Foreword by Alexander R. Stones with X-ray attenuation profiles similar to calcium appear blue while stones with profiles similar to uric acid appear red Figure 5.

Accurate measurement on restaging examinations is important for guiding management, especially for patients in clinical trials in which tumor response is reliant on serial measurements according to Response Evaluation Criteria in Solid Tumors RECIST or World Health Organization WHO criteria, for example.
The cross-sectional nature of CT may to some degree allow noninvasive assessment of the coronary artery wall.
Finally, DECT can help assess response to treatment related to locoregional targeted therapies, such as ablation eg, radiofrequency, microwave, cryotargeted radiation therapy eg, protonsand intra-arterial therapy eg, selective internal radiation therapy [SIRT] and transarterial chemoembolization [TACE].
Utility of iodine overlay technique and virtual unenhanced images for the characterization of renal masses by dual-energy CT. Dual-energy CT in patients suspected of having renal masses: can virtual nonenhanced images replace true nonenhanced images?
However, cysts can be differentiated from small hypodense masses ie, metastases on iodine images in a DECT acquisition because a metastasis will show iodine uptake while a cyst will not Figure 3.
