Computed tomography dose index and spatial resolution in abdominal ct: phantom study

(IJRE) International Journal of Research and Ethics (ISSN 2665-7481), 2022
This work aimed to evaluate the impact of tube current on spatial resolution and volumetric computed tomography dose index (CTDIvol) at abdominal CT examinations. The measurements have been performed on HITACHI CT 16-slice Scanner using twophantoms (PMMA and Catphan 500) for evaluating the CTDIvol and spatial resolution. two tube voltages of 120KVp and

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Development of a synthetic phantom for the selection of optimal scanning parameters in CAD-CT colonography [PDF]

, 2006
The aim of this paper is to present the development of a synthetic phantom that can be used for the selection of optimal scanning parameters in computed tomography (CT) colonography. In this paper we attempt to evaluate the influence of the main scanning

Optimizing Radiation Risk Assessment in CT Imaging: Establishing Institutional Diagnostic Reference Levels and Personalized Dose Strategies for Chest, Abdomen, and Pelvis Scans

Tomography
Background: As a diagnostic radiology procedure, computed tomography (CT) contributes to patient radiation exposure; hence, it deserves special consideration. The use of diagnostic reference levels (DRLs) is an efficient way to optimize patient radiation

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

The effectiveness and cost-effectiveness of computed tomography screening for coronary artery disease : systematic review [PDF]

, 2006
Coronary heart disease (CHD) is one of the main causes of mortality and morbidity in the UK and other Western countries. The disease can be asymptomatic until the first event, which may be a fatal myocardial infarction (heart attack).
