Although dual-energy CT (DECT) was first conceived in the 1970s, it was not widely used for
CT indications. Recently, the simultaneous acquisition of volumetric dual-energy data has …

Computed tomography (CT) has evolved into a powerful diagnostic tool, and it is impossible
to imagine current clinical practice without CT imaging. Because of its widespread …

The use of additional spectral filtration for dual‐energy (DE) imaging using a dual‐source
CT (DSCT) system was investigated and its effect on the material‐specific was evaluated for …

The energy spectrum of X-ray photons after passage through an absorber contains
information about its elemental composition. Thus, tissue characterisation becomes feasible …

Computed tomographic (CT) coronary angiography is a well-established, noninvasive
imaging modality for detection of coronary stenosis, but it has limited accuracy in …

OBJECTIVE. The objective of this study was to investigate the effect on radiation dose and
image quality of the use of additional spectral filtration for dual-energy CT using dual-source …

Photon-counting computed tomography (PCCT) uses a photon counting detector to count
individual photons and allocate them to specific energy bins by comparing photon energy to …

Purpose To determine the iodine contrast-to-noise ratio (CNR) for abdominal computed
tomography (CT) when using energy domain noise reduction and virtual monoenergetic …

OBJECTIVE. The purpose of this study was to evaluate the image quality, radiation dose,
and diagnostic accuracy of dual-energy CT angiography (CTA) compared with 3D rotational …

OBJECTIVE. CT myocardial perfusion imaging is rapidly becoming an important adjunct to
coronary CT angiography for the anatomic and functional assessment of coronary artery …
