Background Material decomposition of dual-energy computed tomography (DECT) enables subtraction of calcified plaque. Purpose To evaluate the accuracy of lumen area measurement in calcified plaque by subtraction of DECT and to determine the effect of contrast material concentration, lumen diameter, density, and thickness of calcified plaque for the measurement. Material and Methods Vessel phantoms were made with six lumen diameters (5.7, 4.9, 3.9, 3.0, 1.9, and 1.3 mm) and six types of calcified…

Photon-Counting Detector CT-Based Vascular Calcium Removal Algorithm
This phantom study shows that a novel calcium-removal image reconstruction algorithm (PureLumen) using a first-generation dual-source PCD-CT effectively decreases blooming artifacts caused by heavily calcified plaques and improves image interpretability.
Quantitative benchmarking of iodine imaging for two CT spectral imaging technologies: a phantom study
Quantitative measurements of post-processed images are dependent on the concentration of iodine, the phantom size and different technologies, however, this study indicates that the iodine maps are reliable for quantification of iodine.

[Dual energy CT of the peripheral arteries: a phantom study to assess the effect of automatic plaque removal on stenosis grading].
Automatic DE-based plaque removal is highly effective for heavily calcified plaques and high luminal enhancement in larger diameter vessels > or = 5 mm), however, accuracy is limited for low density calcified plaque, lower luminal enhancements and smaller caliber vessels mainly due to poor specificity.
Calcified vascular plaque specimens: assessment with cardiac dual-energy multidetector CT in anthropomorphically moving heart phantom.
Dual-energy multidetector CT with novel postprocessing techniques enhanced accuracy of calcified plaque quantification by reducing effects of tissue blooming and beam hardening beyond single- energy multidETector CT.
The Value of Dual-Energy Bone Removal in Maximum Intensity Projections of Lower Extremity Computed Tomography Angiography
DEBR provides significant advantages, even over manually corrected SBBR, as it can effectively help to cope with the data load of CT angiography exams and enables the removal of intraluminal plaques, which provides a benefit for the estimation of the residual lumen.
Dual-Energy CT Angiography in Peripheral Arterial Occlusive Disease
DE-CTA is a feasible and accurate diagnostic method in the assessment of symptomatic peripheral arterial occlusive disease and superior to the conventional bone removal technique and less dependent on vessel wall calcifications.

Spectral DE MDCT imaging of ex vivo atherosclerotic coronary arteries allows successful tissue characterization and enhances depiction of coronary lumen.
Dual-energy CT head bone and hard plaque removal for quantification of calcified carotid stenosis: utility and comparison with digital subtraction angiography
Dual-energy head bone and hard plaque removal is a promising tool for the evaluation of densely calcified carotid stenosis and sensitivity and specificity to detect hemodynamically relevant (>70%) stenosis was 100% and 92%, respectively.
Carotid Computed Tomography Angiography With Automated Bone Suppression: A Comparative Study Between Dual Energy and Bone Subtraction Techniques
Both bone suppression techniques could be applied successfully in 25 patients with high overall image quality and BSCTA showed excellent results for vessel integrity and was superior to DE in most of the vessels in or at the skull base.
