Chest 121 A and B; Talc

Chest 121 A: Talc

Chest 121 B C

Chest 121 B; Talc

I try not to publish more than one version of an image, although whilst going through the production of the picture it is tempting to save different renderings. In this instance I present two versions because they are so different and both appeal for different reasons. The only technical difference between them is a change in application of filters, but the outcome is strikingly different.

The chest X-ray in this image is a museum case of a man who suffered for years with recurrent pneumothorax, which is leakage of air into the chest cavity, causing the underlying lung to collapse. After several emergency admissions to hospital, they performed a procedure to prevent the lung collapsing by encouraging the lung to adhere to the chest wall known as pleurodesis. The pleura is the membrane that lines the chest cavity and can be stripped off in a major surgical procedure to make the layers stick together. However there are several non-surgical techniques for pleurodesis, all require induction of pleural inflammation. The method of choice at the time was to introduce talc; that is to puff finely ground talcum powder, into the chest cavity. This sets up a reaction and the two inflamed layers of pleura stick together.

This picture taken during a thorascopic procedure gives an idea of the talc as it flies into the chest cavity.

Thorascopic insufflation

Insufflation of talc thoroscopically. Image acknowledgement:

On an X-ray talc is visible as a white line, or plaque, around the lung. The radiologist only sees what appears to be pleural calcification that can have several possible causes including industrial lung diseases like asbestosis, previous bleeding, and infections like tuberculosis. It can be difficult to choose between them by appearance alone. It’s crucial to get the diagnosis right for on-going medical management, so to make a right diagnosis the radiologist relies heavily on a good medical history from the referring physician.

Both images show the X-ray and the talc can be seen over the right lung. I have tried to represent both the flying dusty talc and inflammatory reaction on the pleural surface artistically.

    Again you really make me think! The two are very different, thanks for posting both. I am so thankful I can breathe deeply.

      Thankyou Anne Rose. The chest X-ray is the wilderness of radiology and a source of constant fascination for me. To be able to use them as an element in my art – and indeed to direct my art is a privilege.

        Dear Xray artist
        I would like to see an image of the sinuses colorized and reversed negative so that it looks psychedelic.

        I want to put one in my office when I’m a doctor. Are you up to this?

        Of course!

        Hi Elaine,
        I’ve just obtained a very nice picture of the facial sinuses. Still interested in a picture/ It will be my interpretation but i might just do one anyway, for fun. Tony
