If back pain with suspected tumor, fracture or infection, what imaging would you order?

• A. MRI Of The Spine
• B. X-Ray Of The Lumbar Spine
• C. CT Scan Of The Chest
• D. Ultrasound Of The Abdomen

Answer: (B)

In back pain where you’re worried about tumor, fracture, or infection, start with a plain X-ray of the lumbar spine. It’s quick, inexpensive, and widely available, and it can immediately show acute fractures, vertebral misalignment, and obvious destructive changes. This initial screen helps triage patients and decide whether more detailed imaging is needed. If the X-ray is abnormal or if suspicion remains despite a normal film, MRI becomes the next step because it is far more sensitive for bone marrow infection (such as vertebral osteomyelitis), discitis, epidural abscess, and for detecting soft-tissue and marrow-replacing tumors. CT offers detailed bone anatomy and is useful in complex fracture assessment but isn’t as good as MRI for infection or marrow-based tumor evaluation. Ultrasound of the abdomen or CT of the chest isn’t appropriate for evaluating spine pathology in this scenario.
