Slicer version: 4.13.0  
I’m performing semantic segmentation of Left Ventricle through 3D slicer and Google Colab.  
I want to create my dataset of images and masks. In order to create my images dataset I loaded the .dcm files of each patient on colab. I expected an exact reproduction between the images on 3D slicer and the images plotted on python . I can’t understand why .  
thank you in advance
