After a car accident
Do you need an MRI after a car accident?
If you want an MRI after your accident, Dr. Jimenez writes the order. He writes it after an evaluation — that is what tells him which study to order and what it should be looking for.
Getting evaluated is quick to arrange: a free phone call first, then an appointment. X-rays are taken here in the office, which for a good number of people answers the question the same day. When an MRI is the right next study, that is the one he orders.
This page explains what an X-ray, a CT and an MRI each show, why the emergency room may not have done the one you are asking about, and how it gets paid for.

First — these need emergency care, not an appointment
Call 911 or go to the nearest emergency room if you have:
- New or worsening weakness in an arm or leg
- Numbness that is spreading
- Loss of bladder or bowel control
- New difficulty walking or keeping your balance
- Severe or worsening headache, confusion, or repeated vomiting
- Chest pain, difficulty breathing, or severe abdominal pain
What an X-ray, a CT and an MRI each show
They are not interchangeable, and the difference is the whole reason this question comes up.
X-ray and CT are excellent at bone. Fractures, dislocations, alignment. CT is also very good at finding acute bleeding. If you had either after your accident and it was clear, a significant fracture is unlikely.
Neither one shows soft tissue well. Ligaments, muscles, tendons, discs and nerves barely register on them. A torn ligament in your neck and a healthy one look much the same on an X-ray.
MRI is what shows those structures. It is the study that answers whether a disc has been pushed against a nerve root, or whether the ligaments that stabilize your spine were strained.
So the useful question is not “should I get a scan” but “which question am I trying to answer” — and that is what an examination establishes.
The words in your report
If you have already had a scan, the report is probably where the worry started. Radiology reports are written for the doctor who ordered them, not for the person they describe, and the vocabulary sounds far worse than most of what it names.
Most of the terms below describe wear rather than injury. Wear-related changes are visible on imaging in a great many people who have no symptoms at all, which is exactly why the examination matters more than the picture — what it establishes is whether the finding explains what you are actually feeling.
- Disc bulge
- The disc extends a little past its normal edge, usually the whole way round rather than at one point.
- Herniated, protruded or extruded disc
- Disc material has been pushed out of shape at a particular spot. The three words describe how far.
- Annular tear
- A tear in the tough outer ring of a disc. Also written as an annular fissure.
- Facet hypertrophy
- The small paired joints at the back of the spine have thickened or enlarged.
- Osteophyte, or bone spur
- Extra bone formed along the edge of a joint or vertebra.
- Foraminal narrowing
- The opening a nerve root passes through on its way out of the spine is narrower than usual.
- Spondylosis
- A general term for wear-related change in the spine, rather than one specific finding.
- Loss of lordosis, or straightening
- The normal forward curve of the neck or low back looks flatter than usual on the image.
- Modic changes
- Changes in the bone next to a disc, described in grades. Common on reports and frequently unrelated to symptoms.
- Cord signal change
- An area of the spinal cord that looks different on the scan. This is one of the few report findings that is followed up urgently.
A report is a description of a picture, not a diagnosis. If you have one, bring it — going through it with the person who examines you is usually shorter and more useful than reading it alone.

Why the emergency room didn’t do an MRI
Because it wasn’t the right tool for the question they were asking. An emergency department after a collision is establishing whether anything could seriously harm you in the next few hours — fractures, bleeding, head injury, organ damage. X-ray and CT answer that quickly and well.
MRI is rarely performed in an emergency department unless there’s a specific red flag. That is not an oversight. It is a different question, asked at a different point in time.
When imaging is actually worth doing
Dr. Jimenez orders imaging when the examination points to it — not automatically, and not everything at once. If an MRI is warranted, he’ll say so and explain why. If it isn’t, he won’t order it.
What usually moves the answer toward imaging is nerve involvement: pain that radiates into an arm or a leg, numbness or tingling, weakness. What usually moves it away is pain that stays local and is already starting to settle.
A scan you didn’t need still shows something. Wear-related changes in the spine are often visible on imaging in people with no symptoms at all, and being told about a finding that isn’t causing your pain is its own kind of harm.
Who pays for an X-ray or an MRI?
For car accident care we don’t bill regular health insurance. Imaging is handled the same two ways as the rest of your treatment — self-pay, or a lien if you qualify, where the cost is settled later out of a settlement rather than out of pocket while your case is open.
It isn’t a separate arrangement you need to work out in advance, and it isn’t something to sort out before contacting us.
How an X-ray or an MRI actually gets ordered
First, a phone call. It is free, it needs no referral and no appointment, and it happens within 24 hours. Tell us what happened and what you are feeling, and you talk it through with the surgeon, Dr. Jimenez .
Then, an appointment. This is where the evaluation happens and where Dr. Jimenez writes the order, because the evaluation is what decides which study you need and what it should be looking for. It is also where an X-ray can be taken on site, which for a good number of people answers the question the same day.
Nobody is asked to decide about a scan before that. What the examination finds is what decides which study is worth doing, and whether one is worth doing at all.
What the 24 hours covers.
A response within 24 hours, and a phone conversation with Dr. Jimenez in that same window if you want one. An in-person appointment often follows quickly, but that depends on scheduling and we won’t name a specific day before we’ve spoken.

Start with the examination
Imaging answers a question. Working out which question is worth asking takes a conversation and an examination, and that can start within 24 hours.
