Ga, radiochemistry, coordination chemistry, conjugation chemistry. Introduction. The number of publications devoted to 6. Ga radiopharmaceutical basic and clinical research has increased drastically during last two years. Rough estimation demonstrates that the number of 6. Ga related scientific articles published during 2. Figure 1. Rather crucial changes and progress occurred during this short period and they influenced the basic perceptions and thus speculation about the nearest 5 1. Nuclear medicine applications and in particular positron emission tomography PET have experienced accelerated development. The major advantage of PET is that it is not only enables in vivo visualization of physiological processes on molecular level in real time, but it also quantifies them by measuring regional concentration of the radiation source. PET employs imaging agents comprising positron emitting radionuclides Figure 2. A, and scanners detecting radiation Figure 2. B. Positron scan registration is based on the 1. V photons arising from the annihilation of positrons with electrons and detection by means of two opposing counters recording only coincident events 1. The registered events are reconstructed into images representing spatial distribution of the radioactivity in a subject. Positron emission is an attribute of neutron deficient nuclides requiring artificial production generally by cyclotrons. However 6. 8Ga is obtained from a 6. Ge6. 8Ga generator system which is simple in use and relatively inexpensive. Fig 1. The fraction of 6. Ga related publications per two successive years except for the periods of 1. Pub.

Fig 2. Schematic representation of PET principle. A After travelling in tissue positron range positron looses energy and annihilates with electron resulting in two 5. V annihilation photons travelling in opposite directions B Annihilation photons are registered externally by radiodetectors consisting of scintillation crystals and photomultiplier tubes and assembled in a ring. Only photons that are registered in coincidence are used for image reconstruction. Click on the image to enlarge. PET has become an established method for medical research and clinical routine diagnostics. Development and availability of new radiopharmaceuticals specific for particular diseases is one of the driving forces of the expansion of clinical nuclear medicine providing early personalized diagnosis and efficient therapy. The future development of 6. Ga radiopharmaceuticals must be put in the context of several aspects such as role of PET in nuclear medicine, unmet medical needs, identification of new biomarkers, targets and corresponding ligands, production and availability of 6. Ga, automation of the radiopharmaceutical production, progress of PET technologies and image analysis methodologies for improved quantitation accuracy, PET radiopharmaceutical regulations as well as radiopharmaceutical chemistry advances. This review presents the prospects of the 6. Ga based radiopharmaceutical development on the basis of the current status of these aspects. Ga has demonstrated its applicability for the labelling of small compounds, biological macromolecules as well as nano and micro particles promoting the growth of PET field 2. The major application domain is oncology however, potential has been demonstrated for imaging of myocardial perfusion, pulmonary perfusion and ventilation as well as inflammation and infection. Imaging of general biologic properties and processes such as proliferation, apoptosis, hypoxia, glycolysis, and angiogenesis have also been investigated. These prerequisites may trigger an explosive progress and introduction of new 6. Ga radiopharmaceuticals into clinics in the nearest future of 5 1. The focus of this critical review resides on the publications from year 2. The achievements in gallium radiopharmaceutical chemistry and imaging agent development from 1. January 2. 01. 1 were addressed in a comprehensive and exhaustive review published earlier 2 and references therein. The explosive growth of publications reflecting the success of 6. Ga applications is remarkable. Another strong indication of the worldwide growth of 6. Ga studies is the First World Congress on Ga 6. PRRT that took place in 2. Role of PET in nuclear medicine. Nuclear medicine is a quickly expanding field for the diagnostics and therapy on cellular and molecular level. Molecular imaging techniques such as PET and Single Photon Emission Computed Tomography SPECT utilize, respectively, positron and gamma emitting radionuclides for the generation of the signal that results in a whole body scan in a single examination. They provide fast and non invasive evaluation of physiology and pathology, and together with external and internal radiotherapy merge into theranostics resulting in personalized medicine 4 7. Imaging diagnostics enables early detection, staging, therapy selection, planning, and monitoring treatment response thus considerably improving cancer therapy. The most pronounced example is the selection of oncological patients for PRRT. Radionuclidic properties and detection techniques determine the advantages of PET over SPECT in terms of 1. However gamma and SPECT scanners are more accessible and have lower cost. Moreover, a wider range of registered gamma emitting radiopharmaceuticals is available, though their price has enhanced currently due to the reduction of public subsidy 8. On the other hand, the shorter scanning time and thus higher throughput of PET decreases the cost per patient examination. Nuclear medicine practice is dominated by 9.
