چکیده
A 64-year old male who underwent a mechanical valve Bentall procedure at another institution presented 1 year postoperatively with fever and dyspnoea. Laboratory investigations revealed Candida albicans infection with a periprosthetic collection. Confusion as to whether the collection was infective endocarditis, a periprosthetic transudate or a mass of haemostatic plugs used intraoperatively was clarified by combined positron emission tomography– computed tomography (PET–CT scans; Fig. 1).

Noninvasive Imaging for the Assessment of Coronary Artery Disease
Noninvasive cardiac imaging is a cornerstone of the diagnostic work-up in patients with suspected coronary artery disease (CAD), cardiomyopathy, heart failure, and congenital heart disease. It is essential for the assessment of CAD from functional and anatomical perspectives, and is considered the gate-keeper to invasive coronary angiography. Cardiac tests include exercise electrocardiography, ...
متن کاملDetection of Alzheimer\\\\\\\'s Disease using Multitracer Positron Emission Tomography Imaging
Alzheimer's disease is characterized by impaired glucose metabolism and demonstration of amyloid plaques. Individual positron emission tomography tracers may reveal specific signs of pathology that is not readily apparent on inspection of another one. Combination of multitracer positron emission tomography imaging yields promising results. In this paper, 57 Alzheimer's disease neuroimaging ini...
متن کاملEvaluation of Cardiac Function Using Fast Computed Tomography
Cardiovascular disease is a major cause of mortality in Western society but at its early phase may manifest as subtle alterations in coronary epicardial or microvascular function, including endothelial dysfunction, abnormal perfusion or permeability, and remodeling, which may precede clinical manifestation of vascular disease. These modifications might be associated with subclinical decline in ...
متن کاملThe effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
متن کاملCoronary Artery Disease No Difference in Cardiac Event-Free Survival Between Positron Emission Tomography-Guided and Single-Photon Emission Computed Tomography-Guided Patient Management A Prospective, Randomized Comparison of Patients With Suspicion of Jeopardized Myocardium
OBJECTIVES We sought to prospectively compare nitrogen-13 (N)-ammonia/fluorodeoxyglucose (FDG) positron emission tomography (PET)–guided management with stress/rest technetium-99m (Tc)-sestamibi single-photon emission computed tomography (SPECT)– guided management. BACKGROUND Patients with evidence of jeopardized (i.e., ischemic or viable) myocardium may benefit from revascularization, whereas ...
