Detection of High-Energy Radiation
Detection of High-Energy Radiation When high-energy radiation interacts with matter, it produces certain physical or chemical changes in matter. These changes, which can be either transitory or permanent, are the…
Cutaneous Extramedullary Hematopoiesis
Cutaneous Extramedullary Hematopoiesis András Schaffer DEFINITION Two categories of extramedullary hematopoiesis (EMH) can be distinguished on the basis of pathogenesis, clinical presentation, and histopathology. In the first category, EMH is…
Radiation Dosimetry
Radiation Dosimetry Radiation is known to produce a number of deleterious effects in a living system. Therefore, it is important to properly assess the benefits and risks to a patient…
Interaction of High-Energy Radiation with Matter
Interaction of High-Energy Radiation with Matter Interaction is a fundamental aspect of nature. Our ability to see, hear, smell, and taste is a vivid manifestation of interaction. This chapter, however,…
Cutaneous Manifestations of Myeloproliferative Neoplasms
Cutaneous Manifestations of Myeloproliferative Neoplasms Richard Danialan Carlos A. Torres-Cabala INTRODUCTION Myeloproliferative neoplasms (MPNs) are a group of hematopoietic disorders characterized by the clonal proliferation of cells in the myeloid…
Radiopharmaceuticals
Radiopharmaceuticals In nuclear medicine, radionuclides are rarely used in their simplest chemical form. Instead, they are incorporated in a variety of chemical compounds that may be of interest because of…
Production of Radionuclides
Production of Radionuclides In 1896, Henry Becquerel discovered that uranium was radioactive. Soon after, other naturally occurring radionuclides such as radium and polonium were discovered. Most naturally occurring radionuclides have…
Leukemia Cutis/Aleukemic Leukemia Cutis/Myeloid Sarcoma
Leukemia Cutis/Aleukemic Leukemia Cutis/Myeloid Sarcoma Kari E. Sufficool John L. Frater INTRODUCTION Acute leukemia may present in a variety of extramedullary tissues with or without bone marrow disease. Though rare,…
Radioactivity: Law of Decay, Half-Life, and Statistics
Radioactivity: Law of Decay, Half-Life, and Statistics Radionuclides are unstable and decay to other nuclides by the processes discussed previously. At what rates do radionuclides decay? Do all radionuclides decay…
Nuclides and Radioactive Processes
Nuclides and Radioactive Processes In the previous chapter, we discussed the structure of the atom and pointed out the importance of electrons and their interaction. In this chapter, we discuss…
