While many radiopaque objects can be seen on a standard abdominal x-ray, not all are visible due to various factors such as the object's material density, size, or location. Some objects may be obscured by other anatomical structures or substances within the gastrointestinal tract. Materials like plastic, wood, or thin metals might not be seen on x-ray, thus additional imaging techniques such as CT scans may be necessary to identify these items.
