Diagnostic Reference Levels (DRLs) and Image Quality Evaluation for Digital Mammography in a Nigerian Facility

Journal of Nigerian Society of Physical Sciences, 2022
Diagnostic Reference Levels (DRLs) for digital mammography and image quality evaluation are important optimization tools in medical imaging. High quality mammograms are essential to the successful early detection of breast cancer.

Computed radiography

Biomedicine & Pharmacotherapy, 1998
In several medical centers computed radiography has almost completely replaced the use of conventional screen-film systems for general radiography. The aim of this paper is to explain the basic principles of the four most frequently numerical detectors used in the world, with emphasis on the phosphor plates, which are the most frequently used both in ...

Overcoming breath-hold difficulties with GRASP VIBE for contrast-enhanced MRI liver and pancreas to improve image diagnostic quality

BMJ Open Quality
Contrast-enhanced MRI is essential for the evaluation and characterisation of indeterminate liver and pancreatic lesions. Conventional volumetric 3D T1-weighted sequences, such as the volumetric interpolated breath-hold examination (VIBE), play a key ...

Statistical Uncertainty in Quantitative Neutron Radiography

, 2017
We demonstrate a novel procedure to calibrate neutron detection systems commonly used in standard neutron radiography. This calibration allows determining the uncertainties due to Poisson-like neutron counting statistics for each individual pixel of a ...

Neutron radiography based visualization and profiling of water uptake in (un)cracked and autonomously healed cementitious materials [PDF]

, 2016
Given their low tensile strength, cement-based materials are very susceptible to cracking. These cracks serve as preferential pathways for corrosion inducing substances.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.
