• #### Cognitive Behavioral Therapy Lowers Elevated Functional Connectivity in Depressed Adolescents ﻿

(Elsevier, Elsevier, 2017-03-01)
Imaging studies have implicated altered functional connectivity in adults with major depressive disorder (MDD). Whether similar dysfunction is present in adolescent patients is unclear. The degree of resting-state functional ...
• #### Comparison of Gated and Ungated Black-Blood Fast Spin-echo MRI of Carotid Vessel Wall at 3T. ﻿

(Japan Society of Magnetic Resonance in Medicine, Japan Society of Magnetic Resonance in Medicine, 2016-07-11)
PURPOSE: Multi-slice ungated double inversion recovery has been proposed as an alternative time-efficient and effective sequence for black-blood carotid imaging. The purpose of this study is to evaluate the comparative ...
• #### Decisional impulsivity and the associative-limbic subthalamic nucleus in obsessive-compulsive disorder: stimulation and connectivity. ﻿

(Oxford University Press, Oxford University Press, 2017-02)
Why do we make hasty decisions for short-term gain? Rapid decision-making with limited accumulation of evidence and delay discounting are forms of decisional impulsivity. The subthalamic nucleus is implicated in inhibitory ...

• #### Experimental characterisation of bubbly flow using MRI ﻿

(2011-11-08)
This thesis describes the first application of ultra-fast magnetic resonance imaging (MRI) towards the characterisation of bubbly flow systems. The principle goal of this study is to provide a hydrodynamic characterisation ...
• #### fMRI evidence for areas that process surface gloss in the human visual cortex. ﻿

(Elsevier, Elsevier, 2015-04-01)
Surface gloss is an important cue to the material properties of objects. Recent progress in the study of macaque's brain has increased our understating of the areas involved in processing information about gloss, however ...
• #### Geniculo-Cortical Projection Diversity Revealed within the Mouse Visual Thalamus ﻿

(PLOS, 2016-01-04)
• #### Improved quantification in small animal PET/MR ﻿

(2015-10-06)
In translational medicine, complementary functional and morphological imaging techniques are used extensively to observe physiological processes in vivo and to assess structural changes as a result of disease progression. ...

• #### Magnetic Resonance Imaging-Based Assessment of Carotid Atheroma: a Comparative Study of Patients with and without Coronary Artery Disease. ﻿

(Elsevier, Elsevier, 2017-02)
$\textit{Background:}$ Functional magnetic resonance (MR) imaging of atheroma using contrast media enables assessment of the systemic severity of atherosclerosis in different arterial beds. Whether black-blood imaging has ...
• #### Sensory cortical response to uncertainty and low salience during recognition of affective cues in musical intervals ﻿

(Public Library of Science (PLoS), Public Library of Science (PLoS), 2017-04-19)
Previous neuroimaging studies have shown an increased sensory cortical response (i.e., heightened weight on sensory evidence) under higher levels of predictive uncertainty. The signal enhancement theory proposes that ...
• #### Short-term changes in arterial inflammation predict long-term changes in atherosclerosis progression. ﻿

(Springer, Springer, 2017-01)
$\textit{Purpose}$: It remains unclear whether changes in arterial wall inflammation are associated with subsequent changes in the rate of structural progression of atherosclerosis. $\textit{Methods}$: In this sub-study ...
• #### Targeted transperineal biopsy of the prostate has limited additional benefit over background cores for larger MRI-identified tumors ﻿

(Springer, 2015)
• #### Three-dimensional black-blood T2 mapping with compressed sensing and data-driven parallel imaging in the carotid artery. ﻿

(Elsevier BV, Elsevier BV, 2017-04)
PURPOSE: To develop a 3D black-blood T₂ mapping sequence with a combination of compressed sensing (CS) and parallel imaging (PI) for carotid wall imaging. MATERIALS AND METHODS: A 3D black-blood fast-spin-echo (FSE) sequence ...
• #### Utilisation of novel magnetic resonance imaging features in the diagnosis and understanding of multiple sclerosis ﻿

(Department of Clinical Neurosciences, University of Cambridge, 2016)
There is no single test clinically available that is independently diagnostic for multiple sclerosis (MS). Currently MS is diagnosed using a combination of clinical evaluation and investigations including magnetic resonance ...
