Corneal Densitometry with Galilei Dual Scheimpflug Analyzer [PDF]
Photonics, 2023 This study aims to apply the densitometry distribution analysis (DDA) method to study corneal densitometry depending on age and corneal region from Galilei Dual Scheimpflug Analyzer tomography. A total of 83 healthy participants aged 39.02 ± 18.34 years (

Corneal Densitometry in Keratoconus
Cornea, 2014 The aim of this study was to compare corneal densitometry measured by Scheimpflug tomography in normal and keratoconic eyes and to assess the differences in densitometry values among the stages of keratoconus.Keratoconic and normal corneas were examined using the Pentacam. Corneal densitometry was measured over a 12-mm diameter area, divided by annular

Scientific Reports, 2023 The healthy cornea is transparent, however, disease can affect its structure, rendering it more or less opaque. The ability to assess the clarity of the cornea objectively could thus be of considerable interest for keratoconus patients. It has previously

Frontiers in Endocrinology, 2021 X-linked hypophosphatemic rickets (XLH) is the commonest inherited form of rickets. It is caused by an impaired regulation of fibroblast growth factor 23 (FGF23) due to a PHEX gene mutation, which leads to reduced tubular reabsorption of phosphate and ...

EJNMMI Research, 2020 Background Emphysema severity is frequently measured on CT via densitometry. Correlation with scintigraphic and spirometric functional measures of ventilation or perfusion varies widely, and no prior study has evaluated correlation between densitometry ...

European Journal of Radiology, 1992 In response to our publication (Gluer et al, 1990a), Wilson and colleagues (1990) proposed the adoption of a uniform terminology and corresponding abbreviation for Dual X-ray Absorptiometry (DXA). We supported this suggestion (Gluer et al, 1990b). Since then, the number of papers on DXA has increased considerably.
