Detection of scarred and viable myocardium using a new magnetic resonance imaging technique: blood oxygen level dependent (BOLD) MRI.
BACKGROUND The identification of viable myocardium in patients with impaired left ventricular contraction secondary to coronary heart disease is important clinically as such myocardium is likely to benefit from revascularisation. Blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) relies on changes in deoxyhaemoglobin concentration under stress for signal generation and could b...
متن کاملApplication and advantage of functional magnetic resonance imaging and blood oxygen level dependant (BOLD) imaging modality.
The objective of the study was to introduce the availability of bold imaging facility at Aga Khan University Hospital Karachi for the first time in Pakistan and also to review the practical application and advantages of functional magnetic resonance imaging (fMRI) and blood oxygen level dependant (BOLD) Imaging Procedures. The study was conducted at Aga Khan University Hospital, Karachi from Au...
متن کاملAssessment of significant coronary artery stenosis using blood oxygen level dependent cardiovascular magnetic resonance (BOLD-CMR)
Methods Patients undergoing clinically indicated coronary angiography underwent BOLD CMR scans using a clinical 1.5T scanner. Three short axis BOLD cine images were captured at baseline and during adenosine-induced coronary hyperemia. The mean segmental percent signal intensity (SI) changes were calculated between baseline and hyperemia in the subendocardial myocardium using the 16-segment mode...
متن کاملPhysiological origin of low-frequency drift in blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI).
We investigated the biophysical mechanism of low-frequency drift in blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (fMRI) (0.00-0.01 Hz), by exploring its spatial distribution, dependence on imaging parameters, and relationship with task-induced brain activation. Cardiac and respiratory signals were concurrently recorded during MRI scanning and subsequently removed fr...
