MR Preferred
- Disc herniation Primary neoplasm
- Suspected metastatic neoplasm
- Trauma with associated myelopathy
- Other indications of myelopathy
- Discitis
- Congenital Anomalies
- Stenosis
CT Preferred
- Disc disease when MR is contraindicated
- Bony trauma
- Fine bony detail (facet joints and other)
- Stenosis (MR or CT)
- Congenital anomalies
- May be used in conjunction with MR with or without contrast
- Linear tomography good for C1-2 and odontoid process
- CT Myelography may be used where MRI is contraindicated
Bone Scan
Most sensitive for detecting fracture, primary or secondary neoplasm (excluding multiple myeloma) infection and other selected cases. However, less specific modality. Always send conventional films and medical history

- Carpal tunnel disease
- Triangular fibrocartilage tear of wrist
CT Preferred
- Evaluation of fractures
- Indeterminate bone lesions on MRI
- Conventional films or bone scintigraphy
