Matthews PM, Coatney R, Alsaid H, et al., 2013, Technologies: preclinical imaging for drug development., Drug Discov Today Technol, Vol: 10, Pages: e343-e350
Preclinical imaging with magnetic resonance imaging (MRI), computerised tomography (CT), ultrasound (US), positron emission tomography (PET) or single-photon emission computed tomography (SPECT) enable non-invasive measures of tissue structure, function or metabolism in vivo. The technologies can add value to preclinical studies by enabling dynamic pharmacological observations on the same animal and because of possibilities for relatively direct clinical translation. Potential benefits from the application of preclinical imaging should be considered routinely in drug development.

Gupta RK, Newbould RD, Matthews PM, 2012, Methods of measuring lung water, Journal of the Intensive Care Society, Vol: 13, Pages: 209-215, ISSN: 1751-1437
Pulmonary oedema can result from both cardiogenic and non-cardiogenic aetiologies and is a cause of considerable morbidity and mortality. Accurate methods of quantifying pulmonary oedema are needed for both clinical and research purposes. Applications could include early recognition, and thus prevention, of impending decompensation in heart failure patients, guidance of fluid management in patients with established pulmonary oedema, and as a pharmacodynamic outcome measure for early clinical trials of drugs for the treatment of pulmonary oedema. Magnetic resonance imaging, computed tomography, positron emission tomography, electrical impedance, and thermodilution methods have all been used with the aim of measuring lung water. These methods differ in their accuracy, cost, ionising radiation dose, invasiveness, portability, and ability to provide dynamic measures. To date, none have been established as a 'gold standard' clinical measurement to improve clinical outcomes or to assist drug development. This review aims to discuss each of these methods in turn, focussing on advantages, limitations, and possible future development and applications. © The Intensive Care Society 2012.

Jezzard P, Matthews PM, Smith SM, 2012, Functional magnetic resonance imaging: An introduction to methods, ISBN: 9780191724770
© Oxford University Press 2001. All rights reserved. This book provides an introduction to functional magnetic resonance imaging (fMRI), the scanning technique that allows the mapping of active processes within the brain. There are six sections to the book, with chapters from an international team. Part I provides a broad overview of the field and sets the context. Part II describes the physiological and physical background to fMRI, including coverage of the hardware required and pulse-sequence selection. Practical issues involving experimental design of the paradigms, psycho-physical stimulus delivery, and subject response are covered in Part III, followed by a comprehensive treatment of data analysis in Part IV. Part V deals with practical applications of the technique in the field of neuroscience and in clinical practice. The final section describes how fMRI can be integrated with other neuro-electromagnetic functional mapping techniques.

Matthews PM, 2012, An introduction to functional magnetic resonance imaging of the brain, Functional Magnetic Resonance Imaging: An Introduction to Methods, ISBN: 9780191724770
© Oxford University Press 2001. All rights reserved. This chapter provides an overview of functional magnetic resonance imaging (fMRI) methods and applications, highlighting key concepts and strategies, and includes the full range of techniques by which physiological changes accompanying brain activity are defined. It focuses on the changes in blood oxygenation and flow that have been used for the functional magnetic resonance imaging methods. Direct imaging of the blood flow response using perfusion MRI is also discussed. The study furthermore deals with elegant methods that have been developed and allow an extension of this simple concept for one-dimensional imaging into methods for multi-slice two-dimensional or threedimensional imaging. It outlines the major issues in statistical analysis for fMRI and addresses ways in which the data can be prepared for analysis to minimize artefacts and maximize sensitivity for the detection of activation changes. Finally, the chapter discusses the various applications of fMRI in neuroscience.

Matthews PM, Filippini N, Douaud G, 2012, Brain structural and functional connectivity and the progression of neuropathology in Alzheimer's disease, ISBN: 9781614991533
In our contribution to this special issue focusing on advances in Alzheimer's disease (AD) research since the centennial, we will briefly review some of our own studies applying magnetic resonance imaging (MRI) measures of function and connectivity for characterization of genetic contributions to the neuropathology of AD and as candidate biomarkers. We review how functional MRI during both memory encoding and at rest is able to define APOE4 genotype-dependent physiological changes decades before potential development of AD and demonstrate changes distinct from those with healthy aging. More generally, imaging provides a powerful quantitative measure of phenotype for understanding associations arising from whole genome studies in AD. Structural connectivity measures derived from diffusion tensor MRI (DTI) methods offer additional markers of neuropathology arising from the secondary changes in axonal caliber and myelination that accompany decreased neuronal activity and neurodegeneration. We illustrate applications of DTI for more finely mapping neurodegenerative changes with AD in the thalamus in vivo and for defining neuropathological changes in the white matter itself. The latter efforts have highlighted how sensitivity to the neuropathology can be enhanced by using more specific DTI measures and interpreting them relative to knowledge of local white matter anatomy in the healthy brain. Together, our studies and related work are helping to establish the exciting potential of a new range of MRI methods as neuropathological measures and as biomarkers of disease progression. © 2013 The authors and IOS Press.
