: Many hospitals now use Radio-Frequency Identification (RFID) or barcoded sponges in addition to X-ray markers to provide a second layer of verification.
: Over time, the sponge may appear as a "whirled" or reticular pattern due to the physical structure of the gauze fibers. Xray that includes sponges
: In long-term cases, the body may form a granuloma around the sponge, which can eventually calcify. Clinical Significance and Prevention : These markers allow radiologists to quickly identify
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. which can eventually calcify.
: The most common finding is the visualization of the barium-impregnated thread.
: 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
