Medical imaging is most powerful when it is presented effectively. A disorganized image set, the wrong number of copies, or the wrong format for the setting can undermine an otherwise strong expert presentation. Here is a practical guide to using medical imaging at deposition and trial.
Deposition: What You Need and How Many
At a medical expert deposition, you typically need multiple image sets: one for the witness, one for deposing counsel, one for each additional defense counsel present, and one for the court reporter's record. In multi-party matters, the number of sets can be significant.
All sets should be identical — produced from the same source study with the same organization and labeling. Inconsistencies between sets create unnecessary complications during testimony.
Organizing the Image Set for Testimony
The expert witness should be able to navigate the image set efficiently during testimony. This means clear organization by series and sequence, consistent labeling, and a logical structure that matches how the expert intends to present their findings.
Before the deposition, confirm with your expert how they want the set organized. Some experts prefer chronological organization across multiple studies. Others prefer organization by anatomical region or by the sequence of findings they intend to address.
Trial: Physical Prints, Digital Display, and Large-Format Exhibits
Trial use of medical imaging typically involves multiple formats. Physical image sets for the expert witness on the stand. Digital files for display on courtroom monitors or presentation systems. Large-format exhibit prints for display during testimony or closing argument.
Each format requires different preparation. Digital files for courtroom display need to be high-resolution and organized for easy navigation. Large-format prints need to be produced at a size and resolution appropriate for the display context. Planning these formats in advance — not the week before trial — produces better results.
Coordinating With Your Expert Before Trial
Your expert should review the trial image set before they testify. This allows them to confirm that the images are correct, identify any issues with the set, and prepare their testimony around the specific images they will reference.
If your expert identifies changes or additions after reviewing the trial set, allow time for reprints. Last-minute imaging orders are possible but create unnecessary pressure.
Multi-Party Matters and Duplicate Sets
In matters with multiple defendants or co-counsel, all parties typically need image sets. Producing identical sets from the same source study ensures that all parties — and all experts — are working from the same imaging data. This matters when opposing experts are reviewing the same study and may be asked about specific images during cross-examination.
Timing: Order Early
Professional image sets for deposition and trial should be ordered well in advance. Standard turnaround depends on study size and service type. For trial, order at least two to three weeks in advance to allow time for expert review and any necessary reprints. Rush options are available for deadline-sensitive matters, but early ordering produces better outcomes.
