It has been suggested that the mammalian memory system has both familiarity and recollection components. Recently, a high-capacity network to store familiarity has been proposed. Here we derive analytically the …more
An algorithm for the optimisation of 3D Modified Driven Equilibrium Fourier Transform (MDEFT) sequences for T1-weighted anatomical brain imaging is presented. Imaging parameters are optimised for a clinical whole body …more
Aims To determine the optimal T1 mapping approach to assess myocardial fibrosis at 3T. Methods and results T1 mapping was performed at 3T using the modified look-locker-inversion sequence in 20 …more
Purpose: To optimize the contrast agent dose and delivery rate used in a novel whole-body magnetic resonance angiography (MRA) protocol using a 3.0T MR scanner. Materials and Methods: Six groups …more
Background: Predictive biomarkers (BMs) for EGJAc would optimise treatment selection and avoid ineffective therapy. Metabolic response (MR) defined as >35% decrease in tumour FDG Standardized Uptake Value (SUV) between day …more
The social brain hypothesis, an explanation for the unusually large brains of primates, posits that the size of social group typical of a species is directly related to the volume …more
Intentionality or Theory of Mind is the ability to explain and predict the behaviour of others by attributing to them intentions and mental states and is hypothesised to be one …more
Background. – Abnormalities of orbitofrontal cortex (OFC) sulcogyral patterns have been reported in schizophrenia, but it is not known if these predate psychosis.Methods. – Hundred and forty-six subjects at high …more
IMPORTANCE: Whether conservative management is superior to interventional treatment for unruptured brain arteriovenous malformations (bAVMs) is uncertain because of the shortage of long-term comparative data. OBJECTIVE: To compare the long-term …more
Introduction: To investigate in vivo differences in the distribution of alpha 4 beta 2 subtypes of nAChR using the ligand I-123-5-Iodo-3-[2(S)-2-azetidinylmethoxy] pyridine (5IA-85380) and single photon emission computed tomography (SPECT) …more
Objective: To investigate normalized I-123-5-Iodo-3[2(S)-2-azetidinylmethoxy] pyridine (5IA-85380) single photon emission computed tomography (SPECT) imaging, a marker for the alpha 4 beta 2 nicotinic receptor, as a predictor of cognitive progression …more
Objective: There is little empirical evidence on publication bias in diagnostic test accuracy studies. We evaluated the proportion of abstracts presented at international stroke meetings, which were later published in …more
Background/Aim: The neurological effects of internal carotid artery (ICA) occlusion vary between patients. The authors investigated whether the severity of symptoms in a large group of patients with ipsilateral or/and …more
