Thyroid Disease—Radionuclide Diagnosis and Therapy In 1941, the first patient was treated for thyroid cancer with radioiodine. Since then, radioiodine has proven invaluable in the assessment of thyroid disorders and…

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 (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…

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,…

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…

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…

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….
