Dual-energy X-ray Absorptiometry

Journal of Clinical Densitometry, 2017
Bone 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: Urography

2008
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 ...

Dual-Energy CT: Vascular Applications

American Journal of Roentgenology, 2012
Dual-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 ...

Quantitative Dual-Energy Coronary Arteriography

Investigative Radiology, 1990
Subtraction 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 ...

Dual energy imaging with a dual-layer flat panel detector

Medical Imaging, 2019
Dual Energy (DE) imaging has been widely used in digital radiography and fluoroscopy, as has dual energy CT for various medical applications. In this study, the imaging performance of a dynamic dual-layer a-Si flat panel detector (FPD) prototype was ...

Thoracic Applications of Dual Energy

Radiologic Clinics of North America, 2010
Recent technological advances in multidetector computed tomography (CT) have led to the introduction of dual-source CT, which allows acquisition of CT data at the same energy or at 2 distinct tube voltage settings during a single acquisition. The advantage of the former is improvement of temporal resolution, whereas the latter offers new options for CT

Dual-energy mammography: simulation studies

Physics in Medicine and Biology, 2006
This paper presents a mammography simulator and demonstrates its applicability in feasibility studies in dual-energy (DE) subtraction mammography. This mammography simulator is an evolution of a previously presented x-ray imaging simulation system, which has been extended with new functionalities that are specific for DE simulations.

Dual-energy contrast-enhanced mammography

Radiología (English Edition), 2014
The degree of vascularization in breast lesions is related to their malignancy. For this reason, functional diagnostic imaging techniques have become important in recent years. Dual-energy contrast-enhanced mammography is a new, apparently promising technique in breast cancer that provides information about the degree of vascularization of the lesion ...

Dual-energy Compton scatter tomography

Physics in Medicine and Biology, 1986
A dual-energy Compton scatter imaging technique, analogous to that used in computed tomography and conventional radiography, has been explored. It is shown that this technique allows the photoelectric component of the attenuation factors for the primary and scattered radiations to be derived.

An energy sensitive cassette for dual‐energy mammography

Medical Physics, 1989
A cassette for simultaneously acquiring dual‐energy mammographic images is proposed and studied utilizing a theoretical noise analysis model. The cassette consists of a sandwich of two storage phosphor plates separated by a copper filter. The front, low atomic number, plate was assumed to be comprised of SrFBr and the rear, high atomic number, plate of
