We need your help locating a radiograph that shows the Westermark sign! This rarely seen abnormality has resulted in a dearth of chest x-rays that are available (aka non-copyrighted) for us to include in the Joslin Chest Atlas. With your help, we can include this "phantom" sign into our program and thus, end the mystery that surrounds this finding. Think of this more like a bounty or treasure hunt, rather than an actual contest (some states and countries have weird rules about contests, and we don't feel like involving a team of lawyers). In exchange for your submission, we will reward you with $50.
The Westermark sign is seen on a radiograph of the chest in 2% of patients with a pulmonary embolism (PE). It is a region of vasoconstriction, or oligemia, distal to the PE, presumably due to obstruction of blood flow to the pulmonary vessels. As a result, there is a sharp demarcation of lung avascularity seen as radiotransparency on the plain film.
Here are the rules:
- Send all submissions to [email protected]
- Must be deemed as adequate quality. Generally, must be 640 pixels shortest side and not-overly compressed (uncompressed format is preferred if possible)
- Must be original film (not copyrighted) and not stolen off google images or such (we'll check!)
- Must be readily recognizable as Westermark Sign
- In case of multiple submissions, reward goes to first submitter with appropriate quality image. We reserve right to use any submitted film, however. In other words, if you send a poor image in before someone else sends in a great image, we may choose either at our discretion.
- Reward money paid via bank check.
- All decisions are final.
- Only 1 (one) bounty paid
- Deadline: April 1, 2009

You might also want to check out the Joslin Chest Atlas. It's now available in the iTunes App Store. It's an atlas of thoracic radiography that demonstrates all the key findings on a chest film that you need to know for your medicine and peds rotations.
Check it out and be sure to leave feedback by email or on the iTunes store!
