High-spin states in the odd-odd ${}^{174}$Re have been investigated via the ${}^{152}$Sm(${}^{27}$Al, 5$\mathit{\text{n}}\gamma$)${}^{174}$Re reaction with the help of excitation function, x-$\gamma$, and $\gamma -\gamma$ coincidence measurements. Five rotational bands have been observed and their configurations were assigned based on alignments, band crossing frequencies, electromagnetic properties, and the estimated bandhead excitation energies. Low-spin signature inversion has been identified in the two-quasiparticle bands built on $\pi h_{11/2}\otimes \nu i_{13/2}$, $\pi h_{9/2}\otimes \nu i_{13/2}$, and $\pi 1/2^{-}\left[541\right]\otimes \nu 5/2^{-}\left[512\right]$ configurations. $E2$ interband transitions were analyzed with band-mixing calculations giving information on shapes and shape driving effects for the bands of interest.
