: On an X-ray, this marker appears as a distinct, high-density linear or "ribbon-like" shadow.
: These markers allow radiologists to quickly identify the presence and exact location of a sponge within a patient’s body cavity if the manual sponge count is incorrect. Radiographic Appearance
: A "burlap" or "soap-bubble" appearance may occur if gas becomes trapped within the fibers of the sponge, often indicating a secondary infection or abscess formation. Xray that includes sponges
: Operating room teams perform multiple manual counts of all sponges, needles, and instruments before, during, and after surgery.
: Many hospitals now use Radio-Frequency Identification (RFID) or barcoded sponges in addition to X-ray markers to provide a second layer of verification. : On an X-ray, this marker appears as
In medical imaging, an X-ray that includes sponges typically refers to the detection of a (gossypiboma or textileoma) following a surgical procedure . The Role of Radiopaque Markers
The presence of a sponge on a post-operative X-ray is considered a "never event" in healthcare—a serious, preventable medical error. : Operating room teams perform multiple manual counts
Surgical sponges are not inherently visible on standard X-rays because cotton is radiolucent (transparent to X-rays). To prevent them from being left behind, modern surgical sponges are manufactured with a —usually a thin, blue strip made of barium sulfate.
