Amalgamated reference data for size-adjusted bone densitometry measurements in 3598 children and young adults – the ALPHABET study [PDF]

Journal of Bone and Mineral Research, 2016
The increasing use of dual energy X-ray absorptiometry (DXA) in children has led to the need for robust reference data for interpretation of scans in daily clinical practice.

Quantitative evaluation of corneal epithelial edema after cataract surgery using corneal densitometry: a prospective study

BMC Ophthalmology, 2018
Purpose The optical density of the cornea can be evaluated quantitatively by “densitometry” using a rotating Scheimpflug camera. Densitometry allows evaluation of corneal opacity in the anterior segment of the eye by quantitative measurement of ...

New Methods in Digital Wood Anatomy: The Use of Pixel-Contrast Densitometry with Example of Angiosperm Shrubs in Southern Siberia [PDF]

Biology
This methodological study describes the adaptation of a new method in digital wood anatomy, pixel-contrast densitometry, for angiosperm species. The new method was tested on eight species of shrubs and small trees in Southern Siberia, whose wood ...

Assessment of body composition by whole-body densitometry: what radiologists should know

Radiologia Brasileira, 2022
The analysis of body composition is a fundamental part of a nutritional status assessment, and the use of diagnostic imaging methods has been increasingly required for an adequate characterization of the lean body mass and fat mass.

A protocol for recombinant protein quantification by densitometry

MicrobiologyOpen, 2020
The protein purity is generally checked using SDS‐PAGE, where densitometry could be used to quantify the protein bands. In literature, few studies have been reported using image analysis for the quantification of protein in SDS‐PAGE: that is, imaged with

One-year natural course of corneal densitometry in high myopic patients after implantation of an implantable collamer lens (model V4c)

BMC Ophthalmology, 2020
Background Corneal densitometry, which is also known as corneal backscattering, is a surrogate measure of corneal clarity. The purpose of the study was to investigate the changes in corneal densitometry (CD) after implanting an implantable collamer lens (
