Multi-center pragmatic studies evaluating the time indicator of cardiac perfusion reserve
Ratio of Diastolic to Systolic Duration (D/S) Accuracy Precision Cardiac Reserve Cardiac Safety Fitness
2013/1/28
Background: Since the greater part of coronary blood flow takes place during the diastolic phase of each cardiac cycle, a time indicator of myocardial perfusion reserve, the ratio of diastolic to syst...
Increased Cerebral Cortex Perfusion in Stroke Patients with Cognitive Disorder Following Cilostazol Administration, Two Cases Report
Stroke Cognitive Disorder Brain Perfusion Antiplatelet Drug NIRS
2013/1/30
Objective: In our search for a new augmentation therapy for stroke patients, we administered cilostazol, an antiplatelet agent. Subjects: The patients suffered from mild hemiparesis or cognitive disor...
Neonatal aortic arch hemodynamics and perfusion during cardiopulmonary bypass
Neonatal aortic arch hemodynamics perfusion cardiopulmonary bypass
2009/12/23
The objective of this study is to quantify the detailed three-dimensional (3D) pulsatile
hemodynamics, mechanical loading, and perfusion characteristics of a patient-specific
neonatal aortic arch du...
The Application of Diffusion- and Perfusion-Weighted Magnetic Resonance Imaging in the Diagnosis and Therapy of Acute Cerebral Infarction
Imaging Diagnosis Therapy of Acute Cerebral Infarction
2009/9/8
Diffusion- and perfusion-weighted magnetic resonance imaging (DWI and PWI) was applied for stroke diagnose in 120 acute (<48 h) ischemic stroke patients. At hyperacute (<6 h) stage, it is difficult to...
Adaptive Bayesian Iterative Transmission Reconstruction for Attenuation Correction in Myocardial Perfusion Imaging with SPECT/Slow-Rotation Low-Output CT Systems
Myocardial Perfusion Imaging SPECT/Slow-Rotation Low-Output CT Systems
2009/9/7
Objectives. SPECT/slow-rotation low-output CT systems can produce streak artifacts in filtered backprojection (FBP) attenuation maps, impacting attenuation correction (AC) in myocardial perfusion imag...
BOLD-Perfusion Coupling during Monocular and Binocular Stimulation
BOLD-Perfusion Coupling Monocular Binocular Stimulation
2009/9/4
Previous studies have suggested that during selective activation of a subset of the zones comprising a columnar system in visual cortex, perfusion increases uniformly in all columns of the system, whi...
Transport lattice models of heat transport in skin with spatially heterogeneous, temperature-dependent perfusion
Transport lattice models heat transport skin temperature-dependent perfusion
2010/3/1
The heat transport system model of the skin was solved by exploiting the mathematical analogy between local thermal models and local electrical (charge transport) models, thereby allowing robust, circ...
