A swab or pack left in a patient may not be recognised on a radiograph. This will usually be due to poor observation, but errors may result from unfamiliarity with the pattern of the markers. In addition, some markers may be difficult to detect, though this usually applies only to swabs which are very small or to those produced by some continental manufacturers. It should also be realised that, in a very few hospitals, swabs which do not have an opaque marker may occasionally be used in theatre. All the X-ray detectable swabs provided by the major suppliers in the U.K. are demonstrated.
留在患者体内的拭子或包布在X光片上可能无法被识别。这通常是由于观察不仔细，但也可能是因为不熟悉标记物的样式而导致错误。此外，一些标记物可能难以检测到，不过这通常只适用于非常小的拭子或某些欧洲大陆制造商生产的拭子。还应意识到，在极少数医院，手术室偶尔可能会使用没有不透明标记物的拭子。展示了英国主要供应商提供的所有可通过X光检测的拭子。
