Fractional flow reserve using coronary computed tomography angiography requires at least 64slice coronary computed tomography angiography and cannot be calculated when images lack sufficient quality (HeartFlow, 2013) (11% to 13% in recent studies; Koo et al, 2011; Min et al, 2012; Nakazato et al, 2013; Nørgaard et al, 2014), e.g., in obese individuals (e.g., body mass index, >35 kg/m2). The pre...

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, ...

BACKGROUND Elevated levels of C-reactive protein (CRP) are associated with poor cardiovascular outcomes, even after accounting for traditional cardiovascular risk factors. We sought to analyze the relationship between levels of CRP and coronary plaque subtypes as assessed by coronary computed tomography angiography. METHODS AND RESULTS We evaluated 1004 asymptomatic South Korean subjects (mea...

background: the purpose of this study was to evaluate the infl uence of ejection fraction (ef) on peak aortic time (pat) and  peak aortic enhancement (pae) during coronary computed tomography angiography (cta). materials and methods: one-hundred and twenty patients (64 men, 56 women) underwent measurement of coronary cta with a measurement of ef within 3 months of coronary cta.pearson’s correla...

ultislice computed tomography (MSCT) coronary aniography (CA) has emerged as a powerful noninvasive iagnostic modality to visualize the coronary arteries and the anifestations of coronary atherosclerosis (1). Many reports ave demonstrated that 64-slice computed tomography CT) CA is a viable diagnostic modality to detect or rule out he presence of significant coronary stenoses, but the precise o...

A nomalous origin of the right coronary artery (RCA) arising from the pulmonary trunk (PT) is rare, with an expected incidence of 0.002%. Numerous modalities are available to aid in establishing the diagnosis, including echocardiography, digital subtraction angiography, magnetic resonance angiography, and computed tomography coronary angiography (CTCA). We describe a case of anomalous origin of...

Objectives This was a phase II trial to assess flurpiridaz F 18 for safety and compare its diagnostic performance for positron emission tomography (PET) myocardial perfusion imaging (MPI) with Tc-99m single-photon emission computed tomography (SPECT) MPI with regard to image quality, interpretative certainty, defect magnitude, and detection of coronary artery disease (CAD) ( 50% stenosis) on in...
