Your medical expert witness cannot review, opine, or testify effectively without the right imaging materials. Getting from a DICOM study to a properly prepared expert image set requires more than forwarding a CD. Here is what your expert needs, how to get it to them, and what a professional image set looks like.
What Your Expert Actually Needs
Most medical expert witnesses need two things: the DICOM study for their initial review, and a professional image set for deposition and trial use. The DICOM study allows the expert to review the full imaging data — all series, all slices — using their own DICOM viewing software. The professional image set is what they reference when testifying.
Some experts prefer to identify the specific images they want included in the litigation set after reviewing the full DICOM study. Others provide general instructions. Either way, the expert's input should drive what is included in the final image set.
Sending the DICOM Study to Your Expert
Do not send DICOM files via regular email or public file-sharing services. DICOM files contain protected health information, and unsecured transmission creates compliance exposure for your firm and potentially for your expert.
Options for secure transfer include physical media (mailing the original CD or a copy), secure file transfer services, or working through a litigation imaging service that handles secure transfer as part of the process.
Getting Instructions From Your Expert
Before preparing the final image set, confirm with your expert which images or series they want included, how they want the set organized, and what format they need for their use. Some experts want physical prints. Some want digital files. Some want both.
This step is often skipped, resulting in image sets that do not match what the expert needs for testimony — which means reprints, delays, and additional cost.
What a Professional Image Set Looks Like
A professional litigation image set is organized, labeled, and consistently reproduced. Physical prints are produced on appropriate media — not printed on a standard office printer. Images are organized by series and sequence. Labels are clear and consistent. The set is packaged for professional use, not handed over in a manila envelope with loose prints.
For deposition and trial, the expert should be able to reference specific images quickly and accurately. A disorganized or poorly reproduced image set creates problems on the stand.
Timing and Deadlines
Expert image sets should be ordered well in advance of deposition or trial. Standard turnaround time for a professional imaging service depends on the study size and service type. Rush and expedited options are available for deadline-sensitive matters, but planning ahead produces better results and avoids last-minute complications.
If your expert needs to review the DICOM study before identifying which images to include, build that review time into your timeline.
