Needs and the truly reflective nurse,structure and function of the upstream coronary circulation. Loss of myocytes, replacement fibrosis, and scar tissue formation are associated with regional reductions of blood flow at rest per unit mass. Conversely, regional flow at rest may also be diminished in the absence of structural alteration

Instrumentation and Principles of Imaging: PETected in the body.. As the name suggests, PET imaging is based on radionuclides that decay by positron emission (Figure 1.1A. For example, fluorine-18 (.F)decays to oxygen-18 (.O), emitting a positron (β.) and a neutrino (v.): . (The neutrino does not affect PET imaging and may be ignored in this di

Instrumentation and Principles of CTssing to obtain an exact representation of the slice. Tomographic imaging is important since in conventional projection imaging, such as plane-film x-ray imaging, a small feature may be difficult to visualize because of the confusing superposition of many overlying layers of different structures.

Integrated PET/CTnology. Since the introduction of the first prototype CT scanner in the early 1970s, tomographic imaging has made significant contributions to the diagnosis and staging of disease. Rapid commercial development followed the introduction of the first CT scanner in 1972, and within 3 years of its appea

Principles of Quantitation in Cardiac PETbasic principles of compartment analysis that have been well described by several other authors.. This review emphasizes the most important underlying assumptions and requirements for obtaining accurate quantitative measurements of myocardial perfusion or metabolism from dynamic PET image data.
