Left shoulder radiograph
Left shoulder radiograph seen with artefact over bottom left corner of the radiograph
T-shirt graphic artifact
The patient was wearing a T-shirt with the brand logo ironed on. The decal showed up as shown.
Patient's clothing are one of the common preventable artifacts in radiographs. With imaging systems being largely digitalised, it is important to note its sensitivity to small differences in densities within the exposure field1, and thus picking up on artifacts such as buttons, stitchings, or even graphic prints on T-shirts.
Some artefacts can mimic pathology, and this should be prevented by actively removing anything that could potentially appear as an artifact on the radiograph.
