Compressed Sensing: Applications in Hyperpolarised 3He lung MRI
Introduction The polarisation in hyperpolarised (HP) He MRI is non-renewable and the scan time of both breath-hold and dynamic lung ventilation images is by necessity short. There is thus a demand to reduce the number of RF excitations needed to fully reconstruct an image and to speed up the acquisition. In previous work, parallel RF encoding [1], radial [2] and spiral [3] under-sampling method...
متن کاملAssessment of Cardiac Functions and Inflammation Burden of Ischemic Injury with Integrated Functional and Cellular MRI
INTRODUCTION The aim of this study to investigate the potential of integrated cardiac MRI (CMR) protocols for better assessment and diagnosis of coronary artery disease (CAD), especially for acute coronary syndrome (ACS). CMR has become an essential utility in evaluating various stable cardiovascular diseases, including established CAD. T2-weighted MRI, myocardial perfusion, delayed enhancement...
متن کاملHyperpolarised 3He MRI versus HRCT in COPD and normal volunteers: PHIL trial.
The aim of the present study was to apply hyperpolarised (HP) (3)He magnetic resonance imaging (MRI) to identify patients with chronic obstructive pulmonary disease (COPD) and alpha(1)-antitrypsin deficiency (alpha(1)-ATD) from healthy volunteers and compare HP (3)He MRI findings with high-resolution computed tomography (HRCT) in a multicentre study. Quantitative measurements of HP (3)He MRI (a...
متن کاملInflammation, fracture and bone repair.
The reconstitution of lost bone is a subject that is germane to many orthopedic conditions including fractures and non-unions, infection, inflammatory arthritis, osteoporosis, osteonecrosis, metabolic bone disease, tumors, and periprosthetic particle-associated osteolysis. In this regard, the processes of acute and chronic inflammation play an integral role. Acute inflammation is initiated by e...
متن کاملDirect visualisation of collateral ventilation in COPD with hyperpolarised gas MRI.
BACKGROUND Collateral ventilation has been proposed as a mechanism of compensation of respiratory function in obstructive lung diseases but observations of it in vivo are limited. The assessment of collateral ventilation with an imaging technique might help to gain insight into lung physiology and assist the planning of new bronchoscopic techniques for treating emphysema. OBJECTIVE To obtain ...
