How can hardware disease be diagnosed besides history and signs?

• A. Ultrasound or radiography to detect foreign body or perireticulitis; examination for left-sided abdominal signs; response to magnet therapy supportive
• B. Blood glucose measurement
• C. Endoscopy of esophagus
• D. Skin biopsy

Answer: (A)

Imaging to pinpoint a reticular foreign body and the inflammation around it, together with a careful physical picture from the left side of the abdomen, strengthens the diagnosis beyond what history and general signs provide. Ultrasound or radiography can reveal a metallic object in the reticulum or show signs of perireticulitis, helping confirm hardware disease. Examining for left‑sided abdominal signs aligns with the reticulum’s location and the typical pain pattern from reticulitis. If a magnet is given and the animal shows improvement, that positive response supports the presence of a magnetic foreign body in the reticulum, since the magnet can attract the object and alleviate symptoms. Other tests like measuring blood glucose, esophageal endoscopy, or skin biopsy don’t target the reticulum or the foreign-body/inflammatory process, so they’re not useful for this diagnosis.
