DUAL SOURCE AND DUAL ENERGY COMPUTED TOMOGRAPHY
2023Sophisticated imaging methods, everyone has its special qualities, that radiologists utilize to get precise pictures of the body. Dual-source CT scanners revolve around the patient concurrently at slightly different angles using two X-ray sources and two detector arrays.

Gout is caused by genetic disposition and alimentary factors. It comprises a heterogeneous group of disorders characterized by deposition of monosodium urate crystals in the joints and tendons. Asymptomatic hyperuricemia is common and should not ordinarily be treated. Gout progresses through four clinical phases: asymptomatic hyperuricemia, acute gouty

Dual-energy computed tomography (DE-CT) uses polyenergetic X-rays at 100- and 140-kVp tube energy, and generates 120-kVp composite images that are referred to as polyenergetic images (PEIs). Moreover, DE-CT can produce monoenergetic images (MEIs) at any effective energy level.

Dual-Energy CT: Vascular Applications
American Journal of Roentgenology, 2012Dual-energy CT permits a variety of image reconstructions for the depiction and characterization of vascular disease. Techniques include visualization of low- and high-peak-kilovoltage spectra image datasets and also material-specific reconstructions combining both low- and high-peak-kilovoltage data.This article focuses on four main vascular areas ...

Dual-energy X-ray Absorptiometry
Journal of Clinical Densitometry, 2017Bone mineral density (BMD) measurement by dual-energy X-ray absorptiometry (DXA) is the most commonly used method to assess fracture risk. DXA utilizes two different energy X-rays to calculate BMD and, by comparison to a young normative database, the T-score.

Dual-Energy Computed Tomography: Image Acquisition, Processing, and Workflow.
The Radiologic clinics of North America, 2018Dual energy computed tomography has been available for more than 10 years; however, it is currently on the cusp of widespread clinical use. The way dual energy data are acquired and assembled must be appreciated at the clinical level so that the various ...

In recent years, developments in CT, especially the development of multi-detector CT (MDCT), have provided new and better tools for the evaluation of patients presenting with hematuria and flank pain. The ability of MDCT to provide rapid contiguous thin-slice imaging through the abdomen allowed for the development of CT urography (CTU) protocols for ...

Quantitative Dual-Energy Coronary Arteriography
Investigative Radiology, 1990Subtraction techniques for digital cardiac imaging have been hampered by misregistration artifacts. The use of dual-energy imaging is being evaluated as a means for reducing these artifacts. Results reported previously indicate that the dual-energy technique may be useful for applications such as exercise ventriculography and general quantification ...
