Copper-64 was produced in large scales and high specific activities in late 1990s’ using compact cyclotrons based by 64Ni(p,n)64Cu reaction and many radiopharmaceuticals developed since then by various groups based on interesting physicochemical and nuclear properties of the radionuclide. The unique emission of beta particles as well as positron particles offers a spectacu...

The construction of the 68Ge/68Ga generator has increased application of radiopharmaceuticals labeled with this isotope in medicine. 68Ga-PET is widely employed in the management of neuroendocrine tumors but favorable chemistry with tri- and tetraaza-ring molecules has opened wide range of 68Ga application in other fields of PET imaging. This review covers the radiopharmaceuticals labeled with ...

Nuclear imaging techniques play a role in the assessment and management of patients with sarcoidosis. A variety of radiopharmaceuticals have been introduced for this purpose since the late 1970s. The present chapter focuses on these radiopharmaceuticals, scintigraphic imaging techniques, and their role and clinical value in sarcoidosis. Correlation with other imaging modalities, biochemical par...

The task of single photon emission CT (SPECT) is to visualize the physiological function of various organs with the help of radiopharmaceuticals. But the projection data used for image reconstruction are distorted by several factors, making the reconstruction of a quantitative SPECT image very difficult in most cases. These factors include the attenuation and scattering of gamma rays, collimato...

In the last few decades, a number of radiopharmaceuticals for imaging inflammation have been proposed that differ in their specificity and mechanism of uptake in inflamed foci as compared to the traditional inflammation imaging agents. Radiolabelled cytokines represent a reliable tool for the preclinical diagnosis of chronic inflammatory processes, even before anatomical and functional changes ...

Over the last forty years, a small group of commercial radiopharmaceuticals have found their way into routine medical use, for the diagnostic imaging of patients with infection or inflammation. These molecular radiotracers usually participate in the immune response to an antigen, by tagging leukocytes or other molecules/cells that are endogenous to the process. Currently there is an advancing e...
