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...

BACKGROUND ECG-gated rest-stress cardiac PET can lead to simultaneous quantification of both left ventricular ejection fraction and flow impairment. In this study, our aim was to assess the benefit of rest and stress PET ejection fraction (EF) (EFp) in relation to single-photon emission computed tomography (SPECT) EF (EFs) and echocardiography EF (EFe). To this effect, the EFp was compared with...

OBJECTIVE This study evaluates the feasibility, reliability and reproducibility of electrocardiogram (ECG)-gated intravascular ultrasound (IVUS) image acquisition during automated transducer withdrawal and automated three-dimensional (3D) boundary detection for assessing on-line the result of coronary stenting. BACKGROUND Systolic-diastolic image artifacts frequently limit the clinical applic...

A 76-year-old patient with a history of recurrent left-hemispheric strokes within the last two years was referred for ECG-gated CT angiography (CTA) of the chest for the assessment of aortic plaque burden as a potential source of embolic stroke episodes. CTA revealed significant atherosclerotic plaques in the descending aorta as well as a moderate aortic isthmus stenosis with kinking ( A–C ). S...

Purpose: MR Coronary Artery Imaging (CAI) remains challenging due to the need for high spatial resolution as well as due to constraints imposed by physiological motion and the stringent requirements for fat and muscle suppression to visualize the arterial signal with good contrast. 3D ECG gated balanced steady state free precession (SSFP) imaging has shown great promise due to its high SNR, exc...

UNLABELLED To evaluate myocardial blood flow (MBF) and cardiac function with a single dose of (13)NH(3), electrocardiographically (ECG) gated PET acquisition was performed after a dynamic PET scan was obtained. Gated blood-pool (GBP) imaging with C(15)O PET was also performed to compare the left ventricular ejection fraction (LVEF) obtained using the 2 methods. METHODS Six healthy volunteers ...

introduction: we aimed to investigate the effect of right bundle branch block (rbbb) on perfusion and functional parameters in dipyridamole stress/rest tc99m-mibi gated myocardial perfusion spect (gspect) which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients with...

To evaluate myocardial blood flow (MBF) and cardiac function with a single dose of NH3, electrocardiographically (ECG) gated PET acquisition was performed after a dynamic PET scan was obtained. Gated blood-pool (GBP) imaging with C15O PET was also performed to compare the left ventricular ejection fraction (LVEF) obtained using the 2 methods. Methods: Six healthy volunteers and 34 patients with...

Introduction: We aimed to investigate the effect of right bundle branch block (RBBB) on perfusion and functional parameters in dipyridamole stress/rest Tc99m-MIBI gated myocardial perfusion SPECT (GSPECT) which may be helpful in interpretation of myocardial perfusion imaging.
