Practice and Perception of Radiographers on the Positioning Techniques of Erect Lateral Cervical Spine Radiography in Non-trauma Adult Patients

open access: yesSudan Journal of Medical Sciences, 2021
Background: The visualization of the lower cervical spine (C-spine), including the C7-T1 junction on lateral radiograph is a challenge due to the overlapping of the shoulder girdle.

Cosmic ray radiography of a human phantom [PDF]

open access: yesarXiv, 2021
Cosmic ray muons, that reach the earth's surface, provide a natural source of radiation that is used for radiography. In this paper, we show that radiography using cosmic radiation background provides a method that can be used to monitor bulk aspects of human anatomy. We describe a method that can be used to measure changes in patients as a function of

Plain Radiography of the Hip: A Review of Radiographic Techniques and Image Features

open access: yesHip & Pelvis, 2015
Plain radiographic examination is a fundamental approach to the diagnosis and treatment decision-making of the hip. A thorough understanding of standard radiographic techniques, radiographic anatomy, and disease patterns affecting the hip can be helpful ...

Comparison of Anatomical and Indication-Based Diagnostic Reference Levels (DRLs) in Head CT Imaging: Implications for Radiation Dose Management

open access: yesInternational Journal of Biomedical Imaging
Conclusion:The study highlights that using anatomical DLP DRL values for specific indications in head CT scans can lead to underestimated or overestimated DLP values, making them less reliable for radiation management compared to indication-based DRLs ...

HDAC4 regulates apoptosis in Acan‐CreERT2;HDAC4d/d mice with osteoarthritis by downregulating ATF4

open access: yesFEBS Open Bio, EarlyView.
Using the AcanCreERT2;HDAC4fl/fl genetic mouse model, we further investigated the role of histone deacetylase 4 (HDAC4) in chondrocyte apoptosis. We found that knocking down HDAC4 may be associated with chondrocyte apoptosis by upregulating the activating transcription factor 4 (ATF4)/CAAT/enhancer binding protein homologous (CHOP) signaling pathway ...

Persistent discharge or edema after endoscopic sinus surgery in patients with chronic rhinosinusitis is associated with a type 1 or 3 endotype

open access: yesInternational Forum of Allergy &Rhinology, Volume 13, Issue 1, Page 15-24, January 2023., 2023
Abstract Background Patients with chronic rhinosinusitis (CRS) may have persistence of polyps, discharge, or edema after endoscopic sinus surgery (ESS). Inflammation in CRS can be classified into three endotypes, with the presence of polyps associated with the type 2 endotype.

The optimum angle-cut of collimator for the dense objects in high-energy proton radiography [PDF]

open access: yes, 2015
The use of the minus identity lenses with the angle-cut collimator can achieve high contrast image in high-energy proton radiography. This article presents the principle of choosing the angle-cut aperture of the collimator for the different energies and objects.
