Slicer version: 4.8.1

I’m registering a few SPECT/CT images using the common registration. Everything works relly well and the images seems to be as good as I expect !

 ![image%20(1)](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/7/0/70deeb891ec66d606bf1ba9f5e454e0394591ecf.png)

My problem is when I try to “export” the DICOM file. My image values are higher than 2^16, so, when I export the images, all the values higher than 2^16, appears with no value (an horrible black hole).

 ![image%20(2)](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/1/d/1d282815440c96ddac7edc1d7a2e61b0723e2964.jpeg)

How can I “export” the images without affect the maximum values??.. I need to use this images on another software to quantify the retained activity into the patient, so, It´is not viable rescale the pixel values to be lower than 2^16. I need the pixels values as they are.
