What Is DICOM? A Veterinary Team\'s Guide

DICOM is the standard that packages and moves imaging studies so they can be stored, viewed, shared, and interpreted.

When images don't arrive, arrive under the wrong patient, or can't be opened elsewhere, it's often a DICOM workflow issue.

What DICOM is (in plain English)

DICOM is a standard that tells imaging devices and software how to package a study and transmit it reliably.

It's both the container (how a study is structured) and the delivery rules (how it moves across systems).

Vet imaging is often multi-vendor. DR, ultrasound, dental, CT, PACS, referrals, specialists, DICOM is what keeps studies readable and transferable across those handoffs.

DICOM vs PACS (the confusion explained)

These are related, but not interchangeable.

DICOM, The standard for formatting and exchanging imaging data (images + study details).

PACS, The system that stores, retrieves, and helps you view/share imaging studies, typically using DICOM to ingest and transmit them.

What's inside a DICOM study

A DICOM file isn't just "an image." It's a structured package containing image data plus identifiers that keep a study organized and usable across systems.

The three layers you'll hear about

• Study: the entire exam
• Series: groupings within the study (views, phases, sequences)
• Images: individual frames

Fields that commonly cause real-world issues

• Patient Name / ID: mismatches create duplicates
• Study Date/Time: helps sort, find, and compare
• Modality: DR, US, CT, MRI
• Series Description: improves interpretation clarity
• UIDs: prevents "study collisions"

Many DICOM problems are really patient identity problems, especially when studies are created quickly or the console becomes the source of truth.

Where DICOM shows up in your clinic workflow

Here's the practical chain where DICOM matters:

1. Patient + exam created (practice system, RIS, or modality console)
2. Acquisition (DR, ultrasound, CT, MRI, dental)
3. DICOM send to archive/PACS/viewer
4. Review + annotate in clinic
5. Share with a specialist/consultant when needed

Seven common DICOM problems (and fixes)

1) Study "sent" but never arrived

• Confirm destination details: AE Title, IP/hostname, port.
• Check network/VPN/firewall rules for blocked ports.
• Test with a small send before resending the full study.

2) Study arrived under the wrong patient

• Check whether the console is reusing prior patient records.
• Standardize patient ID entry and naming conventions.
• Where possible, source demographics from an integrated system instead of retyping.

3) Views are in the wrong order or appear "missing"

• Use consistent Series Description naming.
• Confirm the device is sending all series.
• Check receiving-side filters that may hide certain series types.

4) Sharing works internally but fails externally

• External sharing often fails due to network rules or large study size.
• Confirm the recipient's required method (portal upload vs DICOM push vs secure link).

5) Ultrasound/endoscopy won't open as expected

• Some devices export JPEG/PNG by default; confirm you exported true DICOM when needed.
• Confirm the receiving viewer supports the device's DICOM encoding.

6) Duplicate studies pile up

• Duplicates often come from inconsistent patient IDs or resend loops.
• Create a resend protocol: confirm receipt before resending.
• Align patient identity rules across practice system, modality, and PACS.

7) The team loses time chasing "where did the images go?"

• Document the standard steps: when to send, where to send, how to confirm receipt.
• Train on the top failure points.

Tech-friendly DICOM send checklist

Before you hit "Send"

• Confirm patient identity (name + ID) and exam date/time.
• Confirm destination settings (AE Title / IP / port).
• Confirm all required views/series are selected.
• If repeating a send, resend only missing series when possible.

After sending

• Confirm receipt in the PACS/viewer (not just "queued").
• Spot-check that key views open and series order makes sense.
• If sharing externally, confirm the recipient can access the study.
