The aim of this study was to evaluate the diagnostic accuracy of stress myocardial blood flow ratio (SFR), a novel parameter derived from stress dynamic computed tomographic perfusion (CTP), for the detection of hemodynamically significant coronary stenosis.

Myocardial perfusion reflects the macro- and microvascular coronary circulation. Recent quantitation developments using cardiovascular magnetic resonance (CMR) perfusion permit automated measurement c...
The purpose of this study was to evaluate the feasibility of the stenosis-related quantitative perfusion ratio (QPR) for detecting hemodynamically significant coronary artery disease (CAD). Twenty-sev...
Background Direct intraindividual comparison of dynamic CT myocardial perfusion imaging (MPI) and machine learning (ML)-based CT fractional flow reserve (FFR) has not been explored for diagnosing hemo...
Chronic kidney disease (CKD) is associated with endothelial dysfunction and increased cardiovascular mortality. Endothelial dysfunction can be studied measuring myocardial perfusion reserve (MPR). MPR...
Cardiac perfusion PET is increasingly used to assess ischemia and cardiovascular risk and can also provide quantitative myocardial blood flow (MBF) and flow reserve (MBFR) values. These have been show...
New CZT-based SPECT cameras are potentially capable of dynamic 3-D acquisition. Preliminary results suggested that dynamic acquisitions could allow the assessment of myocardial flow reserv...
The ULYSSES study is a single-center, prospective study aimed at evaluation of myocardial ischemia using regadenoson low-dose dynamic computed tomography myocardial perfusion imaging (CTP)...
The overall goal of this project is to compare the absolute quantification of myocardial perfusion done by using CT myocardial perfusion imaging (CT-MPI) and the coronary flow measured by ...
You are being asked to participate in this research study because your doctor has ordered a myocardial perfusion SPECT (Single-Photon Emission Computed Tomography) scan to look at the bloo...
The purpose of this study is to compare pharmacologic stress myocardial perfusion PET with pharmacologic stress myocardial perfusion SPECT in a near-simultaneous, head-to-head comparison i...
The ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung. (Stedman, 25th ed)
The ratio of maximum blood flow to the MYOCARDIUM with CORONARY STENOSIS present, to the maximum equivalent blood flow without stenosis. The measurement is commonly used to verify borderline stenosis of CORONARY ARTERIES.
A gamma-emitting radionuclide imaging agent used in the evaluation of regional cerebral blood flow and in non-invasive dynamic biodistribution studies and myocardial imaging. It has also been used to label leukocytes in the investigation of inflammatory bowel diseases.
A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).
Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm.

Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
