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.

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 ...

Technical innovation changes standard radiographic protocols in veterinary medicine: is it necessary to obtain two dorsoproximal-palmarodistal oblique views of the equine foot when using computerised radiography systems? [PDF]

, 2016
Since the 1950s, veterinary practitioners have included two separate dorsoproximal–palmarodistal oblique (DPr–PaDiO) radiographs as part of a standard series of the equine foot.

The validity and reliability of the exposure index as a metric for estimating the radiation dose to the patient [PDF]

, 2020
Introduction With the introduction of digital radiography, the feedback between image quality and over-exposure has been partly lost which in some cases has led to a steady increase in dose.

Monitoring Three-Dimensional Packings in Microgravity [PDF]

, 2013
We present results from experiments with granular packings in three dimensions in microgravity as realized on parabolic flights. Two different techniques are employed to monitor the inside of the packings during compaction: (1) X-ray radiography is used ...

Scoliosis Surgery in a Patient With Advanced Friedreich's Ataxia—It Is Not Too Late

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Friedreich's ataxia is a multisystem disorder with scoliosis being the most common non‐neurological manifestation. While scoliosis surgery is typically performed in adolescent, ambulatory patients, few data exist on surgical outcomes in patients with advanced disease.
