Status of cardiovascular PET radiation exposure and strategies for reduction: An Information Statement from the Cardiovascular PET Task Force

Cardiovascular positron emission tomography (PET) imaging provides high-quality visual and quantitative myocardial perfusion and function images. In addition, cardiovascular PET can assess myocardial viability, myocardial inflammatory disorders such as cardiac sarcoid, and infections of implanted devices including pacemakers, ventricular assist devices, and prosthetic heart...

Automatic determination of cardiovascular risk by CT attenuation correction maps in Rb-82 PET/CT

Background We investigated fully automatic coronary artery calcium (CAC) scoring and cardiovascular disease (CVD) risk categorization from CT attenuation correction (CTAC) acquired at rest and stress during cardiac PET/CT and compared it with manual annotations in CTAC and with dedicated calcium scoring CT (CSCT). Methods and Results We included 133 consecutive patients...

Coronary Artery Calcification, Epicardial Fat Burden, and Cardiovascular Events in Chronic Obstructive Pulmonary Disease

Rationale Patients with chronic obstructive pulmonary disease (COPD) suffer from significantly more cardiovascular comorbidity and mortality than would be anticipated from conventional risk factors. The aim of this study was to determine whether COPD patients have a higher coronary artery calcium score (CACS) and epicardial fat burden, compared to control subjects, and their...

Low-dose 3D 82Rb PET

Piotr J. Slomka Daniel S. Berman Guido Germano 3D PET systems were introduced for oncological imaging almost a decade ago and are now universally used. The principal advantage of the 3D PET

New Imaging Protocols for New Single Photon Emission CT Technologies

Piotr J. Slomka Daniel S. Berman Guido Germano Nuclear cardiology practitioners have several new technologies available with which to perform myocardial perfusion single photon emission CT (MPS

Supine acceptance of a conventional imaging position may make you less prone to success

Guido Germano Piotr J. Slomka Daniel S. Berman MD Cardiac SPECT imaging, like most medical imaging employing planar and tomographic data acquisition techniques, has traditionally been performed

Automatic and visual reproducibility of perfusion and function measures for myocardial perfusion SPECT

Background We define the repeatability coefficients (RC) of key quantitative and visual perfusion and function parameters that can be derived by the QGS/QPS automated software and by expert visual observer from gated myocardial perfusion SPECT (MPS) scans. Methods Standard QGS/QPS algorithms have been applied to derive quantitative perfusion and function parameters in 200 99mTc...

Motion frozen 18F-FDG cardiac PET

Background PET reconstruction incorporating spatially variant 3D Point Spread Function (PSF) improves contrast and image resolution. “Cardiac Motion Frozen” (CMF) processing eliminates the influence of cardiac motion in static summed images. We have evaluated the combined use of CMF- and PSF-based reconstruction for high-resolution cardiac PET. Methods Static and 16-bin ECG-gated...

Assessment of the relationship between stenosis severity and distribution of coronary artery stenoses on multislice computed tomographic angiography and myocardial ischemia detected by single photon emission computed tomography

Background The relationship between luminal stenosis measured by coronary CT angiography (CCTA) and severity of stress-induced ischemia seen on single photon emission computed tomographic myocardial perfusion imaging (SPECT-MPI) is not clearly defined. We sought to evaluate the relationship between stenosis severity assessed by CCTA and ischemia on SPECT-MPI. Methods and Results...
