Mammography screening in Nigeria – a critical comparison to other countries (2015)
Journal Article
Lawal, O., Murphy, F., Hogg, P., & Nightingale, J. (2015). Mammography screening in Nigeria – a critical comparison to other countries. Radiography, 21(4), 348-351. https://doi.org/10.1016/j.radi.2015.03.015

Breast cancer is a leading cause of death among women, and according to the World Health Organisation (WHO) there will be a significant increase in the incidence of breast cancer in developing countries such as Nigeria by 2030. However, mammography s... Read More about Mammography screening in Nigeria – a critical comparison to other countries.

Lesion detection performance : comparative analysis of low-dose CT data of the chest on two hybrid imaging systems (2015)
Journal Article

PURPOSE:

Incidental findings, discovered in low-dose CT images obtained during hybrid imaging, are an increasing phenomenon with advancing CT technology. Understanding their diagnostic value along with technical limitations is therefore important...

The use of digital health technology and social media to support breast screening (2015)
Book Chapter
Robinson, L., Griffiths, M., Wray, J., Ure, C., & Stein-Hodgins, J. (2015). The use of digital health technology and social media to support breast screening. In P. Hogg, & J. Kelly (Eds.), Digital Mammography : A Holistic Approach (105-111). Springer. https://doi.org/10.1007/978-3-319-04831-4_13

‘Digital health’ is an overarching concept that currently lacks theoretical definition and common terminology. For instance, this broad and emerging field includes all of the following terms within its lexicon: mHealth, Wireless Health, Health 2.0, e...

Observer studies in mammography (2015)
Book Chapter
Hogg, P., Millington, S., Manning, D., & Mraity, H. (2015). Observer studies in mammography. In Digital Mammography (291-302). Springer. https://doi.org/10.1007/978-3-319-04831-4_36

Mammography is a special imaging technique and is unusual in a number of ways: Some of these are technical because of the type of tissue under investigation and some apply to the distinctive nature of the client group. But in one important aspect mam... Read More about Observer studies in mammography.

A phantom-based JAFROC observer study of two CT reconstruction methods : the search for optimisation of lesion detection and effective dose (2015)
Journal Article

Purpose: To investigate the dose saving potential of iterative reconstruction (IR) in a computed tomography (CT) examination of the thorax.
Materials and Methods: An anthropomorphic chest phantom containing various configurations of simulated lesi... Read More about A phantom-based JAFROC observer study of two CT reconstruction methods : the search for optimisation of lesion detection and effective dose.

Breast compression - an exploration of problem solving and decision making in mammography (2014)
Journal Article
Nightingale, J., Murphy, F., Robinson, L., Newton-Hughes, A., & Hogg, P. (2015). Breast compression - an exploration of problem solving and decision making in mammography. Radiography, 21(4), 364-369. https://doi.org/10.1016/j.radi.2014.11.004

Objective: Breast compression decreases radiation dose and reduces potential for motion and geometric unsharpness, yet there is variability in applied compression force within and between some centres. This article explores the problem solving proces... Read More about Breast compression - an exploration of problem solving and decision making in mammography.

Extra patient movement during mammographic imaging : an experimental study (2014)
Journal Article
an experimental study. British Journal of Radiology, 87(1044), https://doi.org/10.1259/bjr.20140241

Objectives: To determine if movement external to the patient occurring during mammography may be a source of image blur. Methods: Four mammography machines with seven flexible and nine fixed paddles were evaluated. In the first stage, movement at the...

Comparison of effective dose and lifetime risk of cancer Incidence of CT attenuation correction acquisitions and radiopharmaceutical administration for myocardial perfusion imaging (2014)
Journal Article

Objective: To measure the organ dose and calculate effective dose from CT attenuation correction (CTAC) acquisitions from four commonly used gamma camera single photon emission CT/CT systems.

Methods: CTAC dosimetry data was collected using therm... Read More about Comparison of effective dose and lifetime risk of cancer Incidence of CT attenuation correction acquisitions and radiopharmaceutical administration for myocardial perfusion imaging.

A 6 year study of mammographic compression force : practitioner variability within and between screening sites (2014)
Journal Article

Background
The application of compression force in mammography is more heavily influenced by the practitioner rather than the client. This can affect client experience, radiation
dose and image quality. This research investigates practitioner comp... Read More about A 6 year study of mammographic compression force : practitioner variability within and between screening sites.

The influence of experience and training in a group of novice observers : A jackknife alternative free-response receiver operating characteristic analysis (2014)
Journal Article
observers : A jackknife alternative free-response receiver operating characteristic analysis. Radiography, 20(4), 300-305. https://doi.org/10.1016/j.radi.2014.06.016

Purpose: The study evaluates the pre- and post-training lesion localisation ability of a group of novice
observers. Parallels are drawn with the performance of inexperienced radiographers taking part in
preliminary clinical evaluation (PCE) and ‘re... Read More about The influence of experience and training in a group of novice observers : A jackknife alternative free-response receiver operating characteristic analysis.

A method to investigate image blurring due to mammography machine compression paddle movement (2014)
Journal Article
Wang, M., Hogg, P., Kelly, J., & Millington, S. (2015). A method to investigate image blurring due to mammography machine compression paddle movement. Radiography, 21(1), 36-41. https://doi.org/10.1016/j.radi.2014.06.004

Background

Compression paddles can move during mammography exposures. Speculation suggests that this movement can cause image blurring. No research has been published to demonstrate whether such movement could cause image blurring.

Aim

Devel... Read More about A method to investigate image blurring due to mammography machine compression paddle movement.
