| Envision Case | Good For | Limit |
|---|---|---|
| Lumbar Spine MRI | Soft tissue, nerves, saucer, excitation | Can not be used with certain alloy implant |
| X-Ray | Bone fractures, alignment, arthritis | Poor soft tissue visualization |
| CT Scan | Bony point, complex fracture | Uses ionizing radiation |
Interpreting the Results
Erst the scan is complete, the images are mail to a radiologist, a physician who specializes in interpreting diagnostic imagery. They will cook a account detail their findings and send it to the doctor who ordered the exam.
