Thrombus Imaging Characteristics and Outcomes in Posterior Circulation Stroke Patients Treated With EVT

Stroke: Vascular and Interventional Neurology, 2022
Background Contrary to anterior circulation stroke, studies on the association between thrombus imaging characteristics and outcomes are scarce in patients with posterior circulation stroke (PCS).

Novel Three-Dimensional and Non-Invasive Diagnostic Approach for Distinction between Odontogenic Keratocysts and Ameloblastomas

Dentistry Journal, 2023
Aim of this study was to demonstrate the diagnostic ability to differentiate odontogenic keratocysts (OKCs) from ameloblastomas (AMs) based on computed tomography (CT) or cone beam computed tomography (CBCT) scans.

Human Bone Typing Using Quantitative Cone-Beam Computed Tomography

International Dental Journal, 2023
Introduction: Bone typing is crucial to enable the choice of a suitable implant, the surgical technique, and the evaluation of the clinical outcome. Currently, bone typing is assessed subjectively by the surgeon.

Influence of 12-bit and 16-bit CT values of metals on dose calculation in radiotherapy using PRIMO, a Monte Carlo code for clinical linear accelerators

Current Directions in Biomedical Engineering, 2019
In this paper, the effect of computed tomography (CT) values of metals in 12-bit and 16-bit extended Hounsfield Unit (EHU) scale on dose calculations in radiotherapy treatment planning systems (TPS) were quantified.

Grating-based X-ray Dark-field Computed Tomography of Living Mice

EBioMedicine, 2015
Changes in x-ray attenuating tissue caused by lung disorders like emphysema or fibrosis are subtle and thus only resolved by high-resolution computed tomography (CT). The structural reorganization, however, is of strong influence for lung function.

Pleural lipomatosis: A new pose of occult pleura effusion

The Egyptian Journal of Bronchology, 2016
Intrathoracic benign neoplasm can develop from any tissue; inside the thoracic cavity, however, infrequently, pleural lipomas can be detected, attributable to unusual adipose tissue in the pleural and subpleural layer.

Evaluation of Hounsfield Numbers and Electron Density for a CT Simulator and Their Importance for Radiotherapy Treatments [PDF]

International Journal of Biomedicine
Since its introduction in the early 1970s, computed tomography (CT) has significantly improved accuracy in radiotherapy planning by enhancing geometric volume definitions and dose calculation distributions.

The Role of Cone-Beam Computed Tomography CT Extremity Arthrography in the Preoperative Assessment of Osteoarthritis

Tomography, 2023
Osteoarthritis (OA) is a prevalent disease and the leading cause of pain, disability, and quality of life deterioration. Our study sought to evaluate the image quality and dose of cone-beam computed tomography arthrography (CBCT-A) and compare them to ...

Cold Quad‐Modal Nanocomplex for Precise and Quantitative In Vivo Stem Cell Tracking

Advanced Functional Materials, EarlyView.
Multimodal albumin–bismuth sulfide–superparamagnetic iron oxide (ABS) nanocomplexes are developed for stem cell tracking across four different imaging modalities: MRI, MPI, MSOT, and CT. Combining its flexibility with high sensitivity, this quad‐modal imaging agent enables a robust quantification of ABS‐labeled stem cells in vivo.
