Hip MRI: What to Expect From Your Scan
When an X-ray says the hip looks fine but the pain says otherwise, the MRI is where the story gets told — labrum, bone marrow, and all.
A hip MRI images the joint's cartilage, labrum, tendons, and bone marrow in detail X-rays cannot touch, usually in 30–45 painless minutes. You lie on your back with the hip positioned in a coil; for labral questions, an MR arthrogram (contrast injected into the joint first) gives the sharpest view. It catches avascular necrosis, stress fractures, and labral tears early — when treatment still works.
Why would I need a hip MRI?
Persistent hip or groin pain with normal X-rays — the classic indications are avascular necrosis (early MRI saves the joint), stress fractures in athletes, occult fractures in older patients, and labral tears in young active people. It is also the problem-solver when hip and groin symptoms refuse to localize, and the pre-treatment map for surgical candidates.
What happens during a hip MRI?
You lie on your back, usually with a soft cushion positioning the hip, inside a coil that frames the joint. The technologist runs sequences while you hold still — most hip MRIs need no contrast and no injection at all. If an arthrogram is planned, the contrast injection into the joint happens first under imaging guidance (see our arthrogram guide), then you proceed to the scanner. The exam takes 30–45 minutes.
What does a hip MRI show?
- Avascular necrosis: the telltale signal change in bone marrow — MRI is the earliest detector
- Stress and occult fractures: bone-marrow edema invisible on X-ray
- Labrum and cartilage: tears and wear, especially with arthrogram contrast
- Tendons and bursae: gluteal tendinopathy, bursitis
- Effusions and synovitis: inflammation inside the joint
Do I need contrast for a hip MRI?
Standard hip MRIs usually need none. Contrast enters as an MR arthrogram — dye injected into the joint space — when the labrum is the question, because the fluid separates torn labrum from bone and makes the detail unmistakable. Your doctor chooses based on the question; you will know before the day.

Frequently asked questions about hip MRI
Is a hip MRI claustrophobic?
Moderately — you lie head-first into the bore. Ask when booking about feet-first positioning; see our claustrophobia guide if enclosed spaces worry you.
Does a hip MRI need dye?
Usually no. Dye enters only for MR arthrograms, when the labrum is the question.
Can an MRI show a hip fracture that X-rays miss?
Yes — that is one of its headline jobs. Bone-marrow edema reveals occult and stress fractures immediately.
What is avascular necrosis?
Bone death from lost blood supply — MRI catches it earliest, when joint-saving treatment still works.
Will the MRI tell me if I need a hip replacement?
It shows the structural damage; the decision combines imaging with symptoms and examination.
Can I drive after a hip MRI?
Yes, unless you had sedation. Standard scans and arthrograms (without sedation) leave you road-ready.
