متن کاملMyocardial microvascular function at rest and stress measured with dynamic contrast-enhanced MRI
Background DCE MRI has been used to estimate myocardial perfusion (blood flow, Fb) but there has been little work published on using this technique to measure related microvascular characteristics, such as microvessel permeability-surface area product (PS) and interstitial volume (extra-vascular extra-cellular volume, ve). The reason may be that transport of Gd-DTPA in resting myocardium is tho...
متن کاملPrecision in measurements of perfusion and microvascular permeability with T1-weighted dynamic contrast-enhanced MRI.
Dynamic contrast-enhanced MRI is used to estimate microvascular parameters by tracer kinetics analysis. The time for the contrast agent to travel from the artery to the tissue of interest (bolus arrival time (BAT)) is an important parameter that must be measured in such studies because inaccurate estimates or neglect of BAT contribute to inaccuracy in model fitting. Furthermore, although the pr...
متن کاملAssessment of Kidney Function Using Dynamic Contrast Enhanced MRI Techniques
Graft failure of kidneys after transplantation is most often the consequence of the acute rejection. Hence, early detection of the kidney rejection is important for the treatment of renal diseases. In this chapter, authors introduce a new automatic approach to classify normal kidney function from kidney rejection using dynamic contrast enhanced magnetic resonance imaging (DCE-MRI). The kidney h...
متن کاملDipyridamole stress and rest gated 99mTc-sestamibi myocardial perfusion SPECT: left ventricular function indices and myocardial perfusion findings
Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. Methods: 297 consecutive patients were studie...
