Pericardial Effusion & Cardiac tamponade

…blood tests and other radiological examinations are most often required, in particular computed tomography (DT) and/or magnetic resonance imaging (MRI). Anatomy of the pericardium…

Coronary CT Angiography and CAD-RADS Reporting

…computed tomographic angiography (CCTA) is a non invasive anatomical examination that depicts the coronary arterial lumen, atherosclerotic plaque, and the severity and distribution of coronary…

Physics of myocardial perfusion imaging (SPECT, PET): Radiotracers, perfusion, blood flow and viability

…high spatial and temporal resolution. PET offers higher spatiotemporal quality, as compared with SPECT. Quantification of blood flow using PET Quantitative PET perfusion imaging offers…

Myocardial Perfusion Imaging With SPECT and PET

…tissue. The distribution of retained tracer provides tomographic information about relative regional perfusion. Imaging is generally performed at rest and during exercise or pharmacological stress…

Contrast-Associated Acute Kidney Injury: Risk Assessment and Prevention

…the occurrence of contrast induced AKI is negligible or very low. Risk rises substantially with chronic kidney disease, particularly diabetic kidney disease and advanced CKD…

Coronary Artery Calcium Scoring: Prognostic Use in Practice

…Visual reporting of coronary calcification using four categories—none, mild, moderate, or severe—is recommended when such findings are available. Further diagnostic imaging solely because…

Intravascular Imaging: IVUS and OCT for PCI Optimisation

…and may not show the EEM through substantial plaque or calcium. Blood clearance is required because blood causes strong backscatter of the light signal. Imaging…

Left Ventricular Segments for Echocardiography and Cardiac Imaging

…is of utmost importance when assessing myocardial structure, perfusion and wall motion. Cardiac planes All imaging modalities define, orient and display the heart using the…

Principles of myocardial perfusion imaging (SPECT, PET), coronary blood flow and flow reserve (CFR)

…not suitable candidates for perfusion imaging. Detecting ischemic regions requires provocation using pharmacologic agents or physical exercise. Pharmacologic agents include dipyridamole, adenosine, regadenoson, and dobutamine…

Exercise Electrocardiographic Testing: Indications, Limitations and Interpretation

…because coronary computed tomography angiography (CCTA) and functional imaging have higher diagnostic performance. Its most consistent contemporary role is therefore the assessment of functional capacity…
