Image Quality and Radiation Dose of Contrast-Enhanced Chest-CT Acquired on a Clinical Photon-Counting Detector CT vs. Second-Generation Dual-Source CT in an Oncologic Cohort: Preliminary Results.
PCD-CT enables oncologic chest-CT with a significantly reduced dose while maintaining image quality similar to a second-generation DSCT for comparable protocol settings, and readers rated image contrast significantly higher in PCD- CT than DSCT images.
Dual-Energy Heart CT: Beyond Better Angiography—Review
In this review, the unique features of dual-energy CT in heart diagnostics are presented and two new CT scanners are presented with much greater capabilities than just performing better ECG-gated angio-CT.
The ultrafast, high‐pitch turbo FLASH mode of third‐generation dual‐source CT: Effect of different pitch and corresponding SFOV on image quality in a phantom study
In the ultrafast, high‐pitch turbo FLASH mode of the third‐generation DSCT, increasing the pitch and lowering the corresponding SFOV will change the image features and cause more artifacts degrading the image quality.
A generalized simultaneous algebraic reconstruction technique (GSART) for dual-energy X-ray computed tomography.
BACKGROUND Dual-energy computed tomography (DECT) is a widely used and actively researched imaging modality that can estimate the physical properties of an object more accurately than single-energy
Volumetric Bone Mineral Density Measurement: for Surgery Specific Bone Volumes
For pre-checking vBMD of surgeon-specific bone volume at implantation candidate sites, a finite element creation-based local v BMD measurement technique was developed and will be added to clinical imaging systems.
Advances in CT Techniques in Vascular Calcification
Some emerging types of CT, such as dual-energy CT and micro CT, have emerged for vascular imaging and providing anatomical information for calcification, and this review focuses on the latest application of various CT techniques in vascular calcification.
Analyzing the identification mechanism of graphite and clay minerals in coal and gangue using X-rays
Three types of chelating depressants were studied for chalcopyrite/pyrite separation, including S-S, S-O, and O-O types, via density functional theory calculations and microflotation. The calculation

Technical principles of dual source CT.
First performance evaluation of a dual-source CT (DSCT) system
First clinical experience shows a considerably increased robustness for the imaging of patients with high heart rates, and the automatic separation of bones and iodine-filled vessels is demonstrated as a potential application of the dual-energy acquisition mode.
Myocardial Ischemia Diagnosed by Dual-Energy Computed Tomography
A dual-source CT scanner is used in dual-energy mode for performing coronary CT angiography in a 74-year–old woman with suspected coronary artery disease and prior abnormal nuclear rest/stress single-photon emission CT (SPECT).
Dual Energy CT of the Chest: How About the Dose?
There is no significant difference in image noise, while CNR can be doubled with optimized dual energy CT reconstructions, while CT can be performed routinely in Dual Energy mode without additional dose or compromises in image quality.
Material differentiation by dual energy CT: initial experience
Results showed that a differentiation and depiction of contrast material distribution is possible in the brain, the lung, the liver and the kidneys with or without the underlying tissue of the organ, and Dual energy CT offers a more specific tissue characterization in CT and can improve the assessment of vascular disease.
Dual- and Multi-Energy CT: Principles, Technical Approaches, and Clinical Applications.
The underlying motivation and physical principles of dual- or multi-energy CT are reviewed, the current and evolving clinical applications are introduced and each of the current technical approaches is described.
Dual-source spiral CT with pitch up to 3.2 and 75 ms temporal resolution: Image reconstruction and assessment of image quality.
The theory for image reconstruction of a high-pitch, high-temporal-resolution spiral scan mode for dual-source CT (DSCT) and its image quality and dose are presented and the resultant reduction in the overall acquisition time may offer clinical advantage for cardiovascular, trauma, and pediatric CT applications.
High-pitch spiral acquisition: a new scan mode for coronary CT angiography.
Prospectively ECG-triggered high-pitch spiral acquisition for coronary CT angiography using dual source CT: technique and initial experience
Prospectively ECG-triggered high-pitch spiral CT acquisition provides high and stable image quality at very low radiation dose.
Dual-energy CT for the assessment of contrast material distribution in the pulmonary parenchyma.
Dual-energy CT is reliable in the detection of defects in pulmonary parenchymal iodine distribution that correspond to embolic vessel occlusion in pulmonary CT angiography.
