Private tags rending in the image as junk data

[xtfer]

Bug Report

Tested in viewer 4.12.12.

Describe the Bug

Images with private tags attempt to render the private tags as image data. This also causes the pixel data to be offset.

What steps can we follow to reproduce the bug?

Tested with both MR images with private Siemens CSA tags and sample CT scan with private header

Possibly related to cornerstonejs/dicomParser#114, though that appears to be already fixed and committed since dicom-parser 1.8.5.

Example showing how this looks when rendering

For anyone who finds this later, the issue was in fact that our DICOM endpoint was returning 'Content-Type: application/dicom` when OHIF was requesting 'Content-Type: application/octet-stream'.
