How to get volumes of 3D image connected components along several time frames of the 3D image?

I'm quiet new user of matlab image processing toolboxes. I am trying to apply a method for segmenting the left and right ventricles from 3D + time MRI images (nifti). After some steps of thresholding ,binarizing and getting the 3D connected components of each time frame I want to calculate (max volume – min volume) for each connected components along the time frames so I can detect the components with the highest difference between min. and max. volume along the time frames. The problem is that for each time frame I have different number of connected components. So how can I trace each components volume throughout the time frames even if a components does not exist in all time frames (due to heart movement) ?
