The Pulmonary System
Introduction: The Ventilation–Perfusion Lung Scan Particles slightly larger than red blood cells can be radiolabeled and injected into a peripheral vein. After passing through the heart and central pulmonary arteries,…
Molecular Imaging
Molecular imaging (MI) allows noninvasive visualization and quantification of functions occurring at the cellular or molecular level. This can involve several different techniques ( Table 5.1 ), but tagging a…
Single-Photon Emission Computed Tomography, Positron Emission Tomography, and Hybrid Imaging
Data Acquisition of Emission Tomographyn Conventional or planar radionuclide imaging suffers a major limitation in the loss of object contrast as a result of background radioactivity. In the planar image,…
Radiopharmaceuticals
An unstable atom that undergoes radioactive decay in order to achieve stability is known as a radionuclide. The radiation these atoms emit can sometimes be used in medical imaging and…
Radioactivity and Radionuclides
In nuclear medicine, radiopharmaceuticals given to the patient emit the radiation used to create images or perform therapy. In order to understand how these agents perform and what safety considerations…
Radiation Detection & Ancillary Instrumentation
The passage of radiation, such as x-rays and gamma rays, through a given material leads to ionizations and excitations that can be used to quantify the amount of energy deposited….
