Imaging is often the part of a case that decides it, and it is also the part that travels worst. A study is reviewed on one workstation, a frame is screenshotted, the screenshot is pasted into a draft, and somewhere in that journey the window settings, the measurement and the link back to the source are lost. A viewer built for medico-legal work should make that journey unnecessary.
Can you view DICOM imaging in a browser?
The first requirement is the most basic. The expert should open CT, MRI, X-ray and ultrasound studies in the browser, with window and level, pan, zoom and measurement, and without asking IT to install a workstation client. The fewer machines and plug-ins involved, the fewer ways the chain of custody can break.
How should imaging annotations be stored?
A finding marked on an image is evidence. It should be stored against the study, not buried in a personal copy of a Word file. That way the instructing firm can see it, a second expert added later can see it, and the annotation carries its own context: the study reference, the date, and who made it.
Measurements you can stand behind
A region of interest or a distance is only useful if it is reproducible. Storing the measurement with the pixel spacing and the window it was taken at means the number on the page can be checked rather than taken on trust. That is exactly the kind of detail an opposing expert will test.
How do you compare two studies over time?
Half of imaging questions are about change over time. Has this progressed since the earlier study. Two synchronised panels, baseline against follow-up, answer that in the workspace instead of in a folder of exported screenshots that nobody can later line up.
If the marked-up frame can drop straight into the report with its caption and study reference attached, the gap between looking and writing closes.
How do you make a radiology measurement defensible?
A measurement on an image is only as good as its provenance. A distance quoted in a report without the pixel spacing it was derived from, or the window it was taken at, is a number an opposing expert can attack and you cannot easily defend. Storing the measurement with those parameters turns it from an assertion into something reproducible. Anyone can open the same study at the same settings and arrive at the same figure, which is the standard the evidence should meet.
What happens when a case moves between experts?
Larger cases rarely stay with one expert. A second opinion is sought, or the case is reallocated, and the imaging has to be handed over. When annotations live in a personal copy of a document, that handover loses everything except the screenshots. When they live against the study, the next expert opens the case and sees exactly what the first expert saw, including the findings, the regions of interest and the notes, with their context intact. The case carries its own history rather than depending on whoever happened to hold the files.
Why it matters
Every export step is a place where fidelity is lost and the audit trail thins out. Keeping the imaging, the annotations and the report in one place keeps the picture in the report tied to the picture in the study.
