You can stack up the dicom images to form a 3D vtkImageData and save it as a vti-file.  
This can be done using a simple python script, and will allow you to inspect your data using Paraview.  
Then, if you want to try the volume rendering of Blender you should convert the vti to a vdb.  
I wasn’t able to setup a converter in python, but in C++ is easy enough.  
You may get the source code [here](https://drive.google.com/file/d/1knPNN-JUAKCdtrE7-cbiL8Bm2zx90dZ1/view?usp=sharing) ( but you have to figure out how to compile it on your os )
