Patients often arrive convinced they need an MRI, or worried that we'll order tests they don't need. Both concerns deserve a straight answer, and the straight answer is this: imaging exists to answer specific questions. If the question matters for your treatment, imaging earns its place. If it doesn't, it adds cost, time, and sometimes anxiety without changing anything we'd do. Not every visit needs a picture; the examination decides.
What X-rays show and when we take them
X-rays image bone. They show alignment of the spine, fractures, degenerative changes such as disc-space narrowing and bone spurs, and structural variations a clinician should know about before treating. They're quick, low-cost, and involve a small radiation dose that modern equipment keeps minimal. We take X-rays in-house, the same visit, when the exam indicates them: no separate imaging center, no second appointment, no waiting days for answers. X-rays are typically indicated after significant trauma, when pain follows an accident, when there's a history that raises concern about bone integrity, or when alignment findings would change how we treat.
What MRI shows and when it's worth it
MRI images soft tissue: discs, nerve roots, the spinal cord, ligaments, and muscles. It uses no radiation, takes longer, and costs considerably more. It's the right tool when we need to see whether a disc is herniated and which nerve it's touching, when neurological signs are progressing, when symptoms haven't responded to an appropriate course of conservative care, or when the findings would change the plan (for example, whether someone is a candidate for spinal decompression or needs a surgical consult). An MRI for routine back pain in the first weeks, with no red flags and no nerve signs, rarely changes treatment, which is why guidelines generally recommend against early imaging in those cases.
After a car accident, imaging does double duty. It guides your care, and it documents your injuries for your PIP claim. Florida gives you only 14 days from the accident to seek care and protect those benefits. Learn how the process works on our auto injury page.
When each is typically indicated
As a general guide: X-ray first when the question is about bone or alignment, such as trauma, suspected degeneration, or pre-treatment structural assessment. MRI when the question is about discs and nerves: radiating pain with numbness or weakness, suspected herniation, or pain that persists despite several weeks of well-directed conservative care. Some situations call for neither right away, and some call for both in sequence. Red flags such as loss of bladder or bowel control, progressive weakness, fever with spine pain, or unexplained weight loss change the calculus entirely and warrant prompt medical evaluation and imaging.
The downside of over-imaging
More pictures are not automatically better care. Imaging frequently finds "abnormalities" in people with no pain at all. Disc bulges and degenerative changes show up on the MRIs of many pain-free adults, and those incidental findings can lead to worry and even unnecessary procedures. A scan can also anchor everyone's attention to a finding that isn't actually generating your symptoms. That's why we let the history and physical examination drive the decision: imaging confirms or rules out what the exam suggests, rather than replacing the exam. If you're unsure whether your symptoms even warrant an evaluation yet, our post on when to see a chiropractor is a good starting point.
Our approach
Every patient gets a thorough history and hands-on exam first. If X-rays are indicated, we take them in-house that same visit and review them with you in plain English. If MRI is indicated, we refer you out and coordinate the results. And if no imaging is needed, we'll tell you that too; honest recommendations cost nothing. Questions about your situation?

Key takeaway: X-rays answer questions about bone and alignment; MRI answers questions about discs and nerves. Neither is automatic. A careful exam should drive the decision, and imaging is worth doing only when the answer would change your care.
