[Assessment of regional myocardial function by ECG-gated myocardial SPECT].
PURPOSES Regional myocardial functional parameters were assessed by ECG-gated myocardial SPECT analysis in normal subjects and ischemic heart diseases. METHODS Normal subjects (13 male and 10 female) and 51 patients with chronic ischemic heart disease underwent ECG-gated myocardial SPECT. A dose of 740 MBq of 99mTc-MIBI was injected at rest, and gated SPECT was performed 60 min later. Wall mo...
متن کاملDiagnostic accuracy of rest/stress ECG-gated Rb-82 myocardial perfusion PET: comparison with ECG-gated Tc-99m sestamibi SPECT.
BACKGROUND Although single photon emission computed tomography (SPECT) and positron emission tomography (PET) myocardial perfusion imaging (MPI) have evolved considerably over the last decade, there is no recent comparison of diagnostic performance. This study was designed to assess relative image quality, interpretive confidence, and diagnostic accuracy by use of contemporary technology and pr...
متن کاملVolumetric assessment of pulmonary nodules with ECG-gated MDCT.
OBJECTIVE The objective of our study was to assess physiologic lung deformation and compression originating from cardiovascular motion and their subsequent impact on determining the volume of small pulmonary nodules throughout the cardiac cycle on ECG-gated MDCT. SUBJECTS AND METHODS Seventy-three small noncalcified pulmonary nodules were identified in 30 patients who underwent ECG-gated MDCT...
متن کامل[Assessment of ECG-gated myocardial SPECT analysis program with cardiac phantom and clinical data].
PURPOSES ECG-gated myocardial SPECT program (QGS) is coming into wide use. This program permits measurement of end-diastolic volume (EDV), and end-systolic volume (ESV) and ejection fraction (EF) by automatic detection of myocardial edges. We assessed the reproducibility, accuracy, factors that affect the measurement of these indices using a cardiac phantom and clinical data. METHODS In the p...
متن کاملNew functional polar maps for estimating regional cardiac function using ECG-gated technetium-99m-tetrofosmin SPECT.
OBJECTIVE The purpose of this work was to develop functional parameters to analyze regional cardiac function using ECG-gated 99mTc-tetrofosmin SPECT. Our goal was to develop a methodology that used slice thickness correction, the generation of a time-activity curve and a polar map. METHODS Fourteen normal patients without evidence of coronary artery disease were studied. One hour after intrav...
