 As a researcher in general we reccomend familiarizing yourself with the various possible sequences of MRI. 
 Some sequences are much more suited to awnser certain questions than others. Generally we could divide MR techniques into structural e.g. T1, T2 and so on,

+functional, diffusion, perfusion, angiographic techniques and spectroscopy. The sequences you work with derterming the shape of files to expect. As an example of what you would expect for structural imaging a 3-D array is the norm, but for diffusion imaging you have a 4D tensor plus .bval and .bvec files.  
 If you work directly with a radiology department you will usually get DICOM files that contain whatever sequences were done.
 However if you obtain images from elsewhere they may come in other formats.
