Hello,
We noticed that in some rare cases, DICOM data isn't properly decoded by BioFormats. In this case, some image pixels show a shift, resulting in a "ghost" image.
Attached images to show the problem: one is with RLE-lossless transfer syntax, and the same image with explicit transfer syntax (converted from the first using dcmdrle tool from DCMTK).
I converted both images to tiff with bfconvert from BioFormats 5.0.5, and adjusted to 8bit in Fiji, in order to see the issue, just open both tiffs and see the "ghost" in the one that were converted from the RLE dicom.
