description Designing and implementing various radionuclide production methods guarantees a sustainable supply, which is important for medical use. The use of medical cyclotrons for radiometal production can increase the availability of gallium-68 (<sup>68</sup>Ga) radiopharmaceuticals. Although generators have greatly influenced the demand for <sup>68</sup>Ga radiopharmaceuticals, the use of medical cyclotrons is currently being explored. The resulting <sup>68</sup>Ga production is several times higher than obtained from a generator. Moreover, the use of solid targets yields end of purification and end of synthesis (EOS) of up to 194 GBq and 72 GBq, respectively. Furthermore, experiments employing liquid targets have provided promising results, with an EOS of 3 GBq for [<sup>68</sup>Ga]Ga-PSMA-11. However, some processes can be further optimized, specifically purification, to achieve high <sup>68</sup>Ga recovery and apparent molar activity. In the future, <sup>68</sup>Ga will probably remain one of the most in-demand radionuclides; however, careful consideration is needed regarding how to reduce the production costs. Thus, this review aimed to discuss the production of <sup>68</sup>Ga radiopharmaceuticals using Advanced Cyclotron Systems, Inc. (ACSI, Richmond, BC, Canada) Richmond, Canada and GE Healthcare, Wisconsin, USA cyclotrons, its related factors, and regulatory concerns.
