Introduction Model-driven registration (MDR) is a general approach to remove patient motion in quantitative imaging. In this study, we investigate whether MDR can effectively correct the motion in free-breathing MR renography (MRR). Materials and met

PURPOSE To measure the transverse relaxation time ( T2∗ ) and apparent diffusion coefficient (ADC) of 19 F-C3 F8 gas in vivo in human lungs at 1.5T and 3T, and to determine the representative distribution of values of these parameters in a cohort o

Background Proton longitudinal relaxation (T1 ) is a quantitative MRI-derived tissue parameter sensitive to myelin, macromolecular, iron and water content. There is some evidence to suggest that cortical T1 is elevated in bipolar disorder and that li

Although impairment in pancreatic insulin secretion is known to precede the clinical diagnosis of type 2 diabetes by up to a decade, fasting blood glucose concentration only rises abnormally once the impairment reaches a critical threshold. Despite i

Purpose To assess alveolar perfusion by applying dynamic susceptibility contrast MRI to 19 F-MRI of inhaled perfluoropropane (PFP). We hypothesized that passage of gadolinium-based contrast agent (GBCA) through the pulmonary microvasculature would re

Purpose To accelerate 19 F-MR imaging of inhaled perfluoropropane using compressed sensing methods, and to optimize critical scan acquisition parameters for assessment of lung ventilation properties. Methods Simulations were performed to determine op

Significance Our current understanding of genetic disease is often inadequate, largely due to genetic background effects that modify disease presentation. This is particularly challenging for rare diseases that lack sufficient numbers of patients for

‘Under your skin’ – imaging in lung disease.
Introduction 19F-MRI of inhaled perfluoropropane (PFP) is a relatively new approach to ventilation imaging, enabling assessment of regional gas distribution without the requirement for hyperpolarization.1 While quantitative measures of pulmonary vent

Background:19F-MRI of inhaled perfluoropropane (PFP) typically involves breath-hold manoeuvres, which may be difficult for patients with respiratory disease. Aim: We assessed the utility of compressed sensing (CS) to reduce 19F-MRI scan time and brea
