Representative computed tomography (CT) findings of the radiofrequency identification (RFID) marking procedure. A, CT findings of possible intrapulmonary injury associated with device manipulation before releasing the RFID marker. B, CT after marking revealed that the intrapulmonary shadow was less obvious, and there was no apparent intrapulmonary hemorrhage. C, CT after RFID marking revealed that the marker was fixed by a nitinol (NiTi) coil anchor. D, There was no apparent intrapulmonary injury after RFID marking.
