Aberrant visual pathway development in albinism: from retina to cortex (2018)
Journal Article
Ather, S., Proudlock, F. A., Welton, T., Morgan, P. S., Sheth, V., Gottlob, I., & Dineen, R. A. (2018). Aberrant visual pathway development in albinism: from retina to cortex. Human Brain Mapping, doi:10.1002/hbm.24411

Albinism refers to a group of genetic abnormalities in melanogenesis that are associated neuronal misrouting through the optic chiasm. Previous imaging studies have shown structural alterations at different points along the visual pathway of people w... Read More

Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI (2018)
Journal Article
Xing, Y., Sapuan, A., Dineen, R., & Auer, D. P. (2018). Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI. Movement Disorders, 33(11), 1792-1799. doi:10.1002/mds.27502

Background: Neuromelanin is a pigment with strong iron-chelating properties preferentially found in dopaminergic neurons of the substantia nigra, pars compacta (SNpc). Parkinson's disease is characterized by pronounced, MRI detectable neuromelanin lo... Read More

The MRI central vein marker: differentiating PPMS from RRMS and ischaemic SVD (2018)
Journal Article
Samaraweera, A. P., Falah, Y., Pitot, A., Dineen, R. A., Morgan, P. S., & Evangelou, N. (2018). The MRI central vein marker: differentiating PPMS from RRMS and ischaemic SVD. Neurology, Neuroimmunology and Neuroinflammation, 5(6), doi:10.1212/NXI.0000000000000496

Objective Can the assessment of brain white matter lesion (WML) central veins differentiate patients with primary progressive MS (PPMS) from relapsing-remitting MS (RRMS) and ischemic small vessel disease (SVD) using 3T MRI. Methods In this... Read More

Recruitment challenges in MRI studies of acute intracerebral haemorrhage: experience from the TICH-2 MRI substudy (2018)
Conference Proceeding
Pszczolkowski, S., Bath, P. M., Sprigg, N., & Dineen, R. A. (2018). Recruitment challenges in MRI studies of acute intracerebral haemorrhage: experience from the TICH-2 MRI substudy

BACKGROUND AND AIMS Magnetic Resonance Imaging (MRI) is widely used in clinical practice and in trials for ischaemic stroke; however, relatively few large multicentre trials for intracerebral haemorrhage have used MRI. We describe the main recruitme... Read More

Evaluation of an internet-based animated preparatory video for children undergoing non-sedated MRI (2018)
Journal Article
McGlashan, H. L., Dineen, R. A., Szeszak, S., Whitehouse, W. P., Chow, G., Love, A., …Wharrad, H. (2018). Evaluation of an internet-based animated preparatory video for children undergoing non-sedated MRI. British Journal of Radiology, 91(1087), doi:10.1259/bjr.20170719. ISSN 0007-1285

Objectives: We evaluate the value of an internet-based educational animated video designed to prepare children for MRI scans, and whether this video reduces scan-related anxiety in children with a neurological disorder, and healthy controls. Meth... Read More

Statistical analysis plan for the ‘Tranexamic acid for hyperacute primary IntraCerebral Haemorrhage’ (TICH-2) trial (2017)
Journal Article
Flaherty, K., Bath, P. M., Dineen, R., Law, Z., Scutt, P., Pocock, S., & Sprigg, N. (in press). Statistical analysis plan for the ‘Tranexamic acid for hyperacute primary IntraCerebral Haemorrhage’ (TICH-2) trial. Trials, 18(1), doi:10.1186/s13063-017-2341-5. ISSN 1745-6215

Rationale Aside from blood pressure lowering, treatment options for intracerebral haemorrhage remain limited and a proportion of patients will undergo early haematoma expansion with resultant significant morbidity and mortality. Tranexamic acid (T... Read More

Altered whole-brain connectivity in albinism (2016)
Journal Article
Welton, T., Ather, S., Proudlock, F. A., Gottlob, I., & Dineen, R. A. (in press). Altered whole-brain connectivity in albinism. Human Brain Mapping, doi:10.1002/hbm.23414. ISSN 1065-9471

Albinism is a group of congenital disorders of the melanin synthesis pathway. Multiple ocular, white matter and cortical abnormalities occur in albinism, including a greater decussation of nerve fibres at the optic chiasm, foveal hypoplasia and nysta... Read More

Cerebral cortical thickness in chronic pain due to knee osteoarthritis: the effect of pain duration and pain densitization (2016)
Journal Article
Alshuft, H., Condon, L., Dineen, R. A., & Auer, D. P. (in press). Cerebral cortical thickness in chronic pain due to knee osteoarthritis: the effect of pain duration and pain densitization. PLoS ONE, 11(9), doi:10.1371/journal.pone.0161687. ISSN 1932-6203

Objective This study investigates associations between cortical thickness and pain duration, and central sensitization as markers of pain progression in painful knee osteoarthritis. Methods Whole brain cortical thickness and pressure pain th... Read More

Animated educational video to prepare children for MRI without sedation: evaluation of the appeal and value (2016)
Journal Article
Szeszak, S., Man, R., Love, A., Langmack, G., Wharrad, H., & Dineen, R. A. (in press). Animated educational video to prepare children for MRI without sedation: evaluation of the appeal and value. Pediatric Radiology, 46(12), doi:10.1007/s00247-016-3661-4. ISSN 0301-0449

Background: MRI scans can be distressing for children and often require sedation. Educating children about what to expect reduces anxiety and increases likelihood of successful non-sedated MRI scans. Multimedia tools are a popular means of education.... Read More
