Non-invasive monitoring of blood gas-induced changes of myocardial oxygenation using oxygen-sensitive CMR
نویسندگان
چکیده
Methods A group of 7 healthy volunteers were instructed to hyperventilate for 1 and 2 minutes followed by a long free breath hold. A second group of 5 aquatic athletes performed a 60s breath hold and a free maximal breath hold. BOLD-sensitive SSFP cines were acquired during breath holds as well as before and after hyperventilation. Changes in signal intensity over the procedures were expressed as % change of the baseline. Capillary blood gases were measured prior to and after the procedures.

Impact of Intermittent Apnea on Myocardial Tissue Oxygenation—A Study Using Oxygenation-Sensitive Cardiovascular Magnetic Resonance
BACKGROUND Carbon dioxide (CO(2)) is a recognized vasodilator of myocardial blood vessels that leads to changes in myocardial oxygenation through the recruitment of the coronary flow reserve. Yet, it is unknown whether changes of carbon dioxide induced by breathing maneuvers can be used to modify coronary blood flow and thus myocardial oxygenation. Oxygenation-sensitive cardiovascular magnetic ...
متن کاملOxygenation-sensitive CMR for assessing vasodilator-induced changes of myocardial oxygenation
BACKGROUND As myocardial oxygenation may serve as a marker for ischemia and microvascular dysfunction, it could be clinically useful to have a non-invasive measure of changes in myocardial oxygenation. However, the impact of induced blood flow changes on oxygenation is not well understood. We used oxygenation-sensitive CMR to assess the relations between myocardial oxygenation and coronary sinu...

Background Diabetes is a chronic disease process, which precedes the development of microvascular dysfunction, detectable as circumferential, subendocardial perfusion deficits on imaging. The full effect of this chronic disease process on myocardial oxygenation is, however, unknown. Studies using oxygen-sensitive Cardiovascular Magnetic Resonance (OS-CMR) have shown that pharmacologically induc...
متن کاملUse of left ventricle blood pool oxygenation-sensitive signal intensity as a measure of arterial hemoglobin saturation
Background Oxygenation-sensitive cardiovascular magnetic resonance (OS-CMR) relies on the attenuating effects of deoxyhemoglobin as an intrinsic contrast. When using OS-CMR to assess myocardial oxygenation, failing to account for effects on myocardial oxygen-sensitive signal intensity (OS-SI) due to arterial hemoglobin desaturation could confound results attributed to changes in perfusion and t...
متن کاملMyocardial oxygenation is maintained during hypoxia when combined with apnea – a cardiovascular MR study
Oxygenation-sensitive (OS) cardiovascular magnetic resonance (CMR) is used to noninvasively measure myocardial oxygenation changes during pharmacologic vasodilation. The use of breathing maneuvers with OS CMR for diagnostic purposes has been recently proposed based on the vasodilatory effect of Co2, which can be enhanced by the additive effect of mild hypoxia. This study seeks to investigate th...
