The present work is a theoretical investigation of nuclear reactions for the production of 52gMn that, with 51Mn and 52mMn, is the only radionuclide that can be used for MultiModal Imaging PET-MRI. A comparison of different reactions is presented considering the reaction natV(α,x)52gMn and the standard production routes with chromium targets. To optimize the production of the radionuclide of interest, an analysis of the cross sections is performed using three nuclear reaction codes (Talys, Fluka and Empire) to select the energy window corresponding to the maximum production of 52gMn and minimum of its contaminants. Numerical computations of the production rate and the time evolution of the produced nuclides are performed, leading to the calculation of the integral yield and of the isotopic and radionuclidic purities for each reaction. The result is that the reaction with natV is very promising and competitive with the investigated standard production routes. Indeed, this reaction shows a radionuclidic purity high enough for clinical applications and an integral yield value even higher than that of the reaction with natural chromium target.
