Tetrofosmin early time gated post-stress single-photon emission computed tomography imaging: Feasibility and potential benefits

Tetrofosmin early time gated post-stress single-photon emission computed tomography imaging: Feasibility and potential benefits

BACKGROUND The purpose of this study is to evaluate the feasibility, the image quality, and the clinical relevance of an early gated post-stress (GPS) single-photon emission computed tomography (SPECT) tetrofosmin (Myoview™-GE Healthcare) acquisition protocol. Time delay between myocardial technetium-labeled tracer administration and SPECT acquisition is usually about 30 minutes after stress, a...

Quantitative single-photon emission computed tomography imaging.

Over the past decade, quantitation of cardiac single-photon emission computed tomography (SPECT) data, once limited to perfusion assessment, has been extended to global and regional function assessment for both the left and the right ventricle, as well as to measurement of additional cardiac parameters of diagnostic and prognostic interest. A number of commercially available quantitative algori...

Comparison of post-exercise and post-vasodilator stress myocardial stunning as assessed by electrocardiogram-gated single-photon emission computed tomography.

BACKGROUND Exercise gated single-photon emission computed tomography (SPECT) using technetium-99m (99mTc)-sestamibi evaluates both myocardial perfusion during stress and wall motion >30 min after the stress, which has the potential to assess not only exercise-induced myocardial ischemia but also the development of myocardial stunning. METHODS AND RESULTS To evaluate the incidence of post-stre...

Single Photon Emission Computed Tomography

[Diagnostic and prognostic evaluation of unstable angina pectoris using ECG-gated single photon emission computed tomography (SPECT) with 99mTc-tetrofosmin].

PURPOSE The purpose of this study is to the diagnostic accuracy and the value as prognostic predictors based on the perfusion and/or functional analysis using the QGS program on 99mTc-tetrofosmin gated SPECT (Tf-QGS-SPECT) in patients with unstable angina pectoris (UAP) who admitted to the CCU. METHODS Fifty seven consecutive patients (37 males and 20 females, mean age: 62 +/- 7 years) with s...
