Getting ERROR: Value exceeds max length for some DICOM tags #374

Closed syedkibrahim closed 6 months ago

syedkibrahim commented 6 months ago

I'm trying to read the DICOM tags using

dcmjs.data.DicomMessage.readFile()

but I am getting the below error for some of the files: Error: Value exceeds max length, vr: AS, value: NX DE_XXXXXXXXXX, length: 16

Same type of error I got for another file: Error: Value exceeds max length, vr: TM, value: NX DE_XXXXXXXXXX, length: 16

I am new to DICOM and DCMJS, so I'm not entirely sure why this error occurs or if there is any workaround for it. Any inputs will be appreciated, thanks.

Hard to say for sure, but if you can replicate this issue with data you can share publicly then someone may be able to have a look.

If you can't share publicly then you might check to see if the dicom file is even valid. This tool is useful: https://www.dclunie.com/dicom3tools/dciodvfy.html but you an also just try loading in a variety of different tools and see if you can narrow down what's different.

I'll close this now but please open a specific issue if you have something you can replicate on data that you can show is valid.

Thanks for the input. We will look into that. We actually tried passing the allowInvalidVRLength: true while performing the.write() function after performing basic de-identification. This seems to be working for us. Just putting it here for any future reference.
