This review outlines the technical aspects and diagnostic performance parameters of nuclear medicine procedures used on patients with disorders of the lower gastrointestinal tract, with the exclusion of techniques using tumor-seeking radiopharmaceuticals. Chronic disorders of the lower gastrointestinal tract often reduce the quality of life because of discomfort from constipation or diarrhea. F...
PET (Positron Emission Tomography) is a powerful imaging technique through which quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body can be realized. Positrons (β +) are positively charged beta particles. They are emitted when the atom is proton enriched. A positron has only a transient existence. After losing all ...
PURPOSE The present review article aims to provide an overview of the available radionuclides for palliative treatment of bone metastases beyond (89)Sr and (153)Sm. In addition, it aims to review and summarize the clinical outcomes associated with the palliative treatment of bone metastases using different radiopharmaceuticals. MATERIALS AND METHODS A literature search was conducted on Scienc...
Bone pain due to skeletal metastases constitutes the most common type of cancer-related pain. The management of bone pain remains challenging and is not standardized. In patients with multifocal osteoblastic metastases, systemic radiopharmaceuticals should be the preferred adjunctive therapy for pain palliation. The lack of general knowledge about radiopharmaceuticals, their clinical utility an...
Abstract Objectives Radiopharmaceuticals, since the discovery of first medical application radioactive isotope, have been essential therapeutics for diagnosis and treatment numerous diseases. Since Directive 2001/83/EC entered in force, European regulatory authorities established a harmonised framework to set quality requirements industrial production radiopharmaceuticals. However, little is kn...
The excretion of radiopharmaceuticals in breast milk is studied to understand excretion mechanisms and to determine recommended breast feeding interruption times for many compounds based on the radiation absorbed dose estimated. A literature review is summarized, providing information on breast milk excretion of many radiopharmaceuticals, including the observed fractions of administered activit...
Radiopharmaceuticals play a critical role in modern medicine primarily for diagnostic purposes, but also for monitoring disease progression and response to treatment. As the use of image has been increased, so has the use of prescription medications. These trends increase the risk of interactions between medications and radiopharmaceuticals. These interactions which have an impact on image by c...
