I encountered an issue while using 3D Slicer.The specific problem is that after importing the images,they become discontinuous and cannot be used for ROI delineation.What could be the possible reason for this?

Try to switch to Advanced mode in the DICOM browser, click Examine, deselect everything and find _the one_ loadable with type “Scalar volume”.
