A general method is proposed for calculating massive Feynman integrals on the basis of a representation of the massive denominators in the form of Mellin–Barnes integrals. This method is used to obtain expressions for some classes of single-loop massive Feynman integrals of propagator and vertex type (for arbitrary values of the powers of the denominators and dimension of space). The results are presented in the form of hypergeometric functions, making it possible to investigate different ranges of variation of the momenta.
