A denosine is widely used for stress-testing in myocardial perfusion imaging. During adenosine infusion, dyspnea is one of the main complaints of patients. The aim of this study was to determine whether dyspnea during adenosine infusion is caused by bronchospasm. Fifty-four patients were enrolled in the study. Seven of these 54 suffered from mild chronic obstructive pulmonary disease (COPD). We co...... hiện toàn bộ
Q-wave regression after acute myocardial infarction assessed by Tl-201 myocardial perfusion SPECTJournal of Nuclear Cardiology - Tập 11 - Trang 165-170 - 2016

The actual relationship between the interval change of myocardial thallium 201 (Tl-201) radioactivity in the infarct area and the pattern of Q-wave regression is still unknown. This study was conducted to evaluate their relationship after acute myocardial infarction (AMI). A total of 30 patients who had a first Q-wave AMI (11 without Q-wave regression and 19 with Q-wave regression) were retrospect...... hiện toàn bộ
Global and regional cardiac dysfunction quantified by 18F-FDG PET scans can predict ventricular arrhythmia in patients with implantable cardioverter defibrillatorJournal of Nuclear Cardiology - Tập 28 - Trang 464-477 - 2021

A low appropriate therapy rate indicates that a minority of patients will benefit from their implantable cardioverter defibrillator (ICD). Quantitative measurements from 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) may predict ventricular arrhythmia (VA) occurrence after ICD placement. We performed a prospective observational study and recruited patients who required ICD place...... hiện toàn bộ
Serial changes of myocardial perfusion imaging in takotsubo and reverse takotsubo cardiomyopathyJournal of Nuclear Cardiology - Tập 29 - Trang 2599-2611 - 2021
Keisuke Miyajima, Kei Tawarahara, Norihito Saito
Takotsubo cardiomyopathy (TTC) shows reversible hypokinesis in the left ventricular (LV) apical-half segment and hyperkinesis in the LV basal-half segment. However, the precise pathophysiological mechanism of TTC is unclear. Therefore, this study sought to clarify the nuclear characteristics, degree of myocardial damage, and serial change of TTC and rTTC using myocardial perfusion imaging. We perf...... hiện toàn bộ
