OBJECTIVES We evaluated a novel protocol of dual-isotope, gated single-photon emission
computed tomographic (SPECT) imaging combined with low and high dose dobutamine as …

Purpose Different criteria to identify residual viability in chronically dysfunctioning
myocardium in patients with coronary artery disease (CAD) can be derived by the combined …

Because of damage to cardiomyocytes and the contractile apparatus, contractile reserve
may be observed less frequently in hibernating than in stunned myocardium. The aim of this …

Noninvasive assessment of myocardial viability has proved clinically useful to distinguish
hibernating or stunned myocardium from irreversibly injured myocardium in patients with …

This study aimed to assess whether contractile reserve evaluation using dobutamine gated
single-photon emission computed tomography (SPECT) improves the capability of …

Background. The simultaneous assessment of perfusion and function with the use of
technetium 99m sestamibi gated single photon emission computed tomography (SPECT) is …

Background—Both radionuclide perfusion tracers and contractile response to dobutamine
have been used to identify hibernating myocardium. The aim was to compare 201Tl …

The purpose of this study was to determine whether exercise technetium-99m sestamibi
gated single-photon emission computed tomography (SPECT) accurately distinguishes …

Both dobutamine stress echocardiography (DSE) and myocardial perfusion scintigraphy are
used to assess myocardial viability. Few studies have compared the data on myocardial …

Only a moderate degree of concordance has been reported between stress-redistribution-
reinjection thallium-201 single photon emission computed tomography (SPECT) and …
