In the CATBITES mnemonic used in radiology, which items are included?

• A. Congenital, Arthritis, Tumor, Blood, Infection, Trauma, Endocrine, Soft tissue
• B. Congenital, Arthritis, Tumor, Blood, Infection, Trauma, Endocrine, Blood vessels
• C. Cardiac, Aneurysm, Tumor, Blood, Infection, Trauma, Endocrine, Soft tissue
• D. Congenital, Arthritis, Tumor, Bleeding, Infection, Trauma, Endocrine, Soft tissue

Answer: (A)

CATBITES is a radiology teaching aid that organizes eight broad categories of pathology you should consider on imaging: Congenital, Arthritis, Tumor, Blood, Infection, Trauma, Endocrine, and Soft tissue. This exact eight-term set is what the best answer reflects, because it preserves every element of the mnemonic as commonly taught. The other options modify one or more terms (for example, substituting Blood vessels or Bleeding, or replacing Congenital with Cardiac), which loses a standard component of the mnemonic and could obscure the intended differential framework. In practice, each category represents a familiar group: congenital anomalies present from birth, arthritis for inflammatory joint disease, tumors for benign or malignant neoplasms, Blood for hemorrhage or hematoma, Infection for osteomyelitis or septic processes, Trauma for injuries, Endocrine for metabolic or hormonal bone changes, and Soft tissue for non-bony structures such as muscles, fat, edema, or soft-tissue masses.
