Myocardial Perfusion Imaging (MPI) is a non-invasive modality with proven diagnostic and prognostic utility in coronary artery disease. We present case of Transthyretin Amyloid Cardiomyopathy (ATTR-CM) where MPI findings were vastly different from Transthoracic Echocardiogram (TTE) Cardiac Magnetic Resonance (CMR). A 78-year-old gentleman presented atypical chest pain to rule out ischemic heart...
Adenosine-induced stress myocardial perfusion imaging using dual-source cardiac computed tomography.
OBJECTIVES This study sought to determine the feasibility of performing a comprehensive cardiac computed tomographic (CT) examination incorporating stress and rest myocardial perfusion imaging together with coronary computed tomography angiography (CTA). BACKGROUND Although cardiac CT can identify coronary stenosis, very little data exist on the ability to detect stress-induced myocardial per...
Two-day stress-rest lower limbs perfusion scan in patients referred for myocardial perfusion imaging
Introduction: Peripheral Vascular Disease (PVD) is a major cause of morbidity and is associated with Coronary Artery Disease (CAD). We aimed to perform Lower Limb Perfusion Scan (LLPS) in patients referred for Myocardial Perfusion Imaging (MPI) and estimate prevalence of PVD in subgroups with normal and abnormal MPI results. We also compared quantitative indices of LLPS in pati...

introduction: peripheral vascular disease (pvd) is a major cause of morbidity and is associated with coronary artery disease (cad). we aimed to perform lower limb perfusion scan (llps) in patients referred for myocardial perfusion imaging (mpi) and estimate prevalence of pvd in subgroups with normal and abnormal mpi results. we also compared quantitative indices of llps in patients with and wit...
Myocardial perfusion imaging (MPI) is a powerful diagnostic and prognostic tool for evaluating coronary artery disease (CAD). Gating myocardial perfusion gives important diagnostic and prognostic information. This 43 years old patient was referred for cardiac scan. Exercise stress test showed > 2 mm horizontal ST segment depression. Cardiac scan was normal except for left ventricular cavity dil...
Background. Heart failure is a major cause of morbidity and death in patients with coronary artery disease (CAD). The aim of this study was to define the incidence and predictors of heart failure during long-term follow-up in patients with suspected CAD referred for stress myocardial perfusion imaging. Methods and Results. We studied 787 patients (mean age, 57 12 years; 470 men) with suspected ...
conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...
introduction: attenuation correction is a useful process for improving myocardial perfusion spect and is dependent on activity and distribution of attenuation coefficients in the body (attenuation map). attenuation artifacts are a common problem in myocardial perfusion spect. the aim of this study was to compare the effect of attenuation correction using different attenuation maps and different...
It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...
