Is it possible to import a DICOM image along with a TIFF formatted mask/ROI?

Hello! I am trying to import a TIFF file that is the ROI mask of a corresponding DICOM image. I am new to ImageJ, as I have recently moved away from Horos for segmentation editing.

My main goal is to overlay the mask on top of the DICOM image in one plugin. Novel to the plugins available and their purposes, I was wondering if anyone had insight on how to approach this issue of mine.

Thank you in advance!
