TL;DR
The integration of DECT-VMIs with the iMAR algorithm appears to improve image quality in post-EVAR CTA by effectively reducing stent-related metal artifacts while enhancing vascular and soft-tissue visualization.
Background/Objectives: This study aimed to investigate the impact of low-energy virtual monoenergetic imaging (VMI) on quantitative and qualitative image characteristics, as well as its effect on the diagnostic assessability of thoracic arteries in photon-counting computed tomography angiography (CTA). Methods: We retr...
For spinal implants, PCD-CT offers effective approaches for metal artifact and 120 keV is preferred and the combination of iMAR and 120 keV introduce new artifacts and requires careful consideration.
Objective To evaluate the clinical utility of a wide-detector CT protocol with variable helical pitch (vHP) for one-stop cardiovascular and cerebrovascular CT angiography. Methods This prospective randomized study enrolled 61 patients (25 in the Group A and 36 in the Group B) with suspected cardiovascular and cerebrova...
MPR image quality is typically inferior to axial images and deteriorates further when derived from thicker axial slices, therefore, appropriate selection of the reconstruction kernel, pixel size and slice thickness are essential to maintain diagnostic image quality.
Background Use of virtual noncontrast (VNC) images from photon-counting CT (PCCT) may reduce radiation dose and support quantitative lung analysis by obviating the need for separate true noncontrast (TNC) acquisitions. Their accuracy for lung densitometry, however, has not been systematically assessed. Purpose To evalu...
The findings support implementing standardized protocols with automatic dual-range reconstructions to enable efficient, individualized carotid plaque assessment in clinical practice and support implementing standardized protocols with automatic dual-range reconstructions for keV selection based on plaque composition.
