Assessment of Takotsubo (ampulla) cardiomyopathy using 99mTc-tetrofosmin myocardial SPECT--comparison with acute coronary syndrome.
UNLABELLED We assessed Takotsubo (ampulla) cardiomyopathy compared with acute coronary syndrome (ACS) using two-dimensional echocardiography and 99mTc-tetrofosmin myocardial SPECT. METHODS We examined 10 patients with Takotsubo cardiomyopathy and 16 with ACS at the time of emergency admission (acute phase), at three to nine days after the attack (subacute phase) and at one month after the att...
متن کامل[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...
متن کاملLong-term prognostic value of exercise technetium-99m tetrofosmin myocardial perfusion single-photon emission computed tomography
BACKGROUND Exercise (99m)Tc-tetrofosmin single-photon emission computed tomography (SPECT) is a useful tool for short- and medium-term risk stratifications. Currently, the long-term prognostic application of this technique has not been evaluated. METHODS AND RESULTS Exercise (99m)Tc-tetrofosmin was performed in 655 consecutive patients. Ten patients who underwent revascularization <60 days af...
متن کاملSingle photon emission computed tomography using 99mTc-HM-PAO in the routine evaluation of Alzheimer's disease.
Regional cerebral blood flow was studied in 7 patients with clinically suspected Alzheimer's disease and 10 normal controls by single photon computed emission tomography (SPECT) using HM-PAO. All patients with Alzheimer's disease and no controls had parietal lobe hypoperfusion which was usually bilateral. In patients with more severe dementia hypoperfusion extended into the frontal lobes. Parie...
متن کاملMonte Carlo Study of the Effect of Backscatter Materail Thickness on 99mTc Source Response in Single Photon Emission Computed Tomography
Introduction SPECT projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. Backscatter constitutes a major part of the scatter contamination in lower energy windows. The current study is an evaluation of the effect of backscatter material on FWHM and image quality investigated by Monte Carlo simulation. Materials and Methods SIMIND program...
