Quantitative 99mTc-Sestamibi Defect Size
Background. Serial myocardial perfusion imaging with "'Tc-sestamibi (MIBI) was used to evaluate infarct risk area and salvage after thrombolysis. The purpose of this investigation was to determine whether changes in MIBI defect size observed after reperfusion may result in part from distortion of regional and global left ventricular geometry. Methods and Results. Twenty-five open-chest dogs wer...
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...
متن کاملCardiac stress imaging for the prediction of very long-term outcomes: Dobutamine stress echocardiography or dobutamine 99mTc-sestamibi SPECT?
BACKGROUND Both dobutamine stress echocardiography (DSE) and myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) are frequently used for cardiac risk stratification. The long-term relative prognostic value of these modalities has not been studied. Therefore, this study evaluated the long-term prognostic value of DSE compared to MPI in patients unable to p...
متن کاملPredicting Recovery of Severe Regional Ventricular Dysfunction Comparison of Resting Scintigraphy With 201T1 and 99mTc-Sestamibi
Background Regional 20`TI activity after resting injection, imaged early and after redistribution, reflects viable myocardium and can predict improved isotope uptake as well as regional and global ventricular function after revascularization. 9'9Tc-sestamibi, a perfusion tracer with favorable imaging characteristics, has distinct kinetics compared with 20`T1, demonstrating minimal redistributio...
