You can do that using dicomwrite :
dicomwrite( imread('image.tif'), 'output.dcm')

Well, sort of.
If you are running a program that demands DICOM input, then chances are high that it looks for specific modalities and specific metadata. For example for 3D reconstruction, it is almost certain to be looking for information about the distance between slices.
In order to insert this information into the .dcm you are writing, by far the easiest way is to use dicominfo() to read the information from a .dcm that has the same kind of set-up that you are creating, and then pass that information structure to dicomwrite() to write out.
Also, some DICOM reconstruction programs will work with sequences of DICOM images, but some of them expect a single .dcm that has multiple slices represented in it. It might be necessary to read a series of .tif images and write them all out to the .dcm at the same time, or it might be necessary to read multiple images from the same .tif and combine them and write that out to the .dcm .
