The extra-cardiac work-up in infective endocarditis (IE) comprises a search for primary and secondary infective foci. Whether (18)FDG-PET/CT or WBC-SPECT/CT is superior in detection of clinically relevant extra-cardiac manifestations in IE is unexplored. The objectives of this study were to identify the numbers of positive findings detected by each imaging modality, to evaluate the clinical relevance of these findings and to define the reproducibility for extra-cardiac foci in patients with definite IE. Each modality was evaluated for numbers and location of positive extra-cardiac foci in patients with definite IE...

Ga prostate-specific membrane antigen (PSMA) PET/CT is increasingly used to evaluate extent of disease in prostate carcinoma. We present a case of subacute cortical cerebral infarct showing focal uptake on PSMA PET/CT. It is an important potential cause of false-positive uptake in this imaging cohort. The patient is an 85-year-old man with a background of nonbacterial thrombotic endocarditis and previous cerebrovascular events. He was referred for PSMA PET/CT for staging of high-risk prostate cancer.

In the 2015 guidelines of the European Society of Cardiology (ESC) and the American Heart Association (AHA) on infective endocarditis, the diagnostics are based on the modified Duke criteria. The diagnosis can be confirmed by a combination of micro-organisms demonstrated in culture or in situ, with the detection of valvular lesions or abscess formation by an imaging modality using echocardiography, positron emission tomography computed tomography (PET/CT), cardio-CT or nuclear medical methods. The management should be further improved by an interdisciplinary endocarditis team in a specifically designated reference center...

Aortic infections are uncommon clinical entities, but are associated with high rates of morbidity and mortality. In this review, we focus on the cross-sectional imaging appearance of aortic infections, including aortic valve endocarditis, pyogenic aortitis, mycotic aneurysm and aortic graft infections, with an emphasis on CT, MRI and PET/CT appearance. Teaching Points • Aortic infections are associated with high morbidity and mortality. • CT, MRI and FDG PET/CT play complementary roles in aortic infection imaging...

Sensitivity and specificity of the modified Duke criteria for native valve endocarditis are both suboptimal, at approximately 80%. Diagnostic accuracy for intracardiac prosthetic material-related infection is even lower. Non-invasive imaging modalities could potentially improve diagnosis of infective endocarditis; however, their diagnostic value is unclear. We did a systematic literature review to critically appraise the evidence for the diagnostic performance of these imaging modalities, according to PRISMA and GRADE criteria...

Cardiovascular implantable electronic device (CIED) infection and prosthetic valve endocarditis (PVE) remain a diagnostic challenge. Cardiac imaging plays an important role in the diagnosis and management of patients with CIED infection or PVE. Over the past few years, cardiac radionuclide imaging has gained a key role in the diagnosis of these patients, and in assessing the need for surgery, mainly in the most difficult cases. Both (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and radiolabelled white blood cell single-photon emission computed tomography/computed tomography (WBC SPECT/CT) have been studied in these situations...

Positron emission tomography (PET) is indicated for a large number of cardiac diseases: perfusion and viability studies are commonly used to evaluate coronary artery disease; PET can also be used to assess sarcoidosis and endocarditis, as well as to investigate amyloidosis. Furthermore, a hot topic for research is plaque characterization. Most of these studies are technically very challenging. High count rates and short acquisition times characterize perfusion scans while very small targets have to be imaged in inflammation/infection and plaques examinations...

PURPOSE: The diagnosis of prosthetic valve (PV) infective endocarditis (IE) and infection of cardiac implantable electronic devices (CIEDs) remains challenging. The aim of this study was to assess the usefulness of (18)F-FDG PET/CT in these patients and analyse the interpretation criteria. METHODS: We included 41 patients suspected of having IE by the Duke criteria who underwent (18)F-FDG PET/CT. The criteria applied for classifying the findings as positive/negative for IE were: (a) visual analysis of only PET images with attenuation-correction (AC PET images); (b) visual analysis of both AC PET images and PET images without AC (NAC PET images); (c) qualitative analysis of NAC PET images; and (d) semiquantitative analysis of AC PET images...

BACKGROUND: In contrast to percutaneous atrial septal occluder device, surgical patch closure of atrial defects was known to be no infective endocarditis risk. CASE PRESENTATION: We herein report the first case of late endocarditis of surgical patch closure of atrial septal defects occurred at 47-year after surgery. On September 2014, a 56-year-old immunocompetent French Caucasian man was admitted into the Emergency Department for 3-week history of headache, acute decrease of psychomotor performance and fever at 40 °C...

AIM: Medical imaging by using FDG-PET/CT (PET-CT) can detect, confirm or eliminate with high sensitivity areas of suspected infections in case of persistent fever of unknown origin in combination with other bacteriological examinations. The aim of this study was to assess the potential role of PET-CT in detecting or excluding infections or other inflammatory processes in patients with congenital heart defects (CHD). In addition we wanted to evaluate the practical impact of PET-CT on the subsequent clinical management...

Infective endocarditis is an endovascular infection usually caused by bacteria. Mortality rate is still approximately 20 %. To improve patients' prognosis by implementation of current diagnostic and therapeutic evidence, the European Society of Cardiology published an updated version of the guidelines for management of infective endocarditis in 2015. It strengthens the role of imaging modalities like PET/CT for detection of infectious foci when echocardiography remains negative and highlights the use of modern tests for identification of possible pathogens...

: Early diagnosis of infective endocarditis (IE) is based on the yielding of blood cultures and echocardiographic findings. However, they have limitations and sometimes the diagnosis is inconclusive, particularly in patients with prosthetic valves (PV) and implantable cardiac electronic devices (ICED). The primary aim of this study was to evaluate the diagnostic accuracy of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in patients with suspected IE an ICED infection...

A best evidence topic was constructed according to a structured protocol. The question addressed was whether (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) aids the diagnosis of prosthetic valve endocarditis (PVE)? A total of 107 publications were found using the reported search, of which 6 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated...

BACKGROUND: 18-Fluorodeoxyglucose positron emission tomography/computerized tomography (FDG PET/CT) scanning has recently been proposed as a diagnostic tool for lead endocarditis (LE). OBJECTIVE: FDG PET/CT might be also useful to localize associated septic emboli in patients with LE.
