Invalid tag in sequence : Unable to parse MR Dicom file in dcmjs. Cornerstone(dicomParser) able to parse and works fine

[subhasishdash]

Describe the Bug

Hi OHIF team, I am using OHIF viewer and it uses dcmjs to parse DICOM files. The attached MR study fails to parse with dcmjs, but it works fine with cornerstone parser Cornerstone file loader

Please let me know how can I fix this.

I tried the following:

• Regenerate dictonary.js from dcmjs, didn't work.
• Tried to add a if condition to getNextSequenceItemData to skip if the var nextTag = Tag.readTag(stream); is 2001, didn't work.

I also saw this fix for dcmtk, not sure if it's related.

Steps to Reproduce

1. Download and unzip the attached study
2. Load viewer.ohif.org/local and load the downloaded image
3. Check browser console for the error : Invalid tag in sequence

The current behavior

Error in browser console : Invalid tag in sequence

The expected behavior

There shouldn't be any error and image should render properly.

Also if possible, please allow to choose between dcmjs or DicomParser in the default.js config.

Please note that currently it works fine with https://github.com/cornerstonejs/dicomParser and am not able to configure it as OHIF uses dcmjs

The file loads fine in cs3d demo https://www.cornerstonejs.org/live-examples/local.html

So I"m wondering why not OHIF, we will investigate, thanks for the report

If you can replicate this with a simple example script then please submit an issue and ideally a fix to dcmjs directly.
