What it is (overview)

An MRI Hip without IV Contrast is a type of non-invasive imaging test that uses a strong magnet and radio waves (not radiation) to create highly detailed pictures of the hip joint and nearby structures. It is a form of diagnostic imaging commonly used in orthopedic evaluation and for many musculoskeletal disorders that cause hip pain, stiffness, or reduced mobility.

The scan can show the bones (femoral head/neck and acetabulum), cartilage and labrum, joint fluid, tendons and muscles around the hip, ligaments, bursae, and portions of the pelvis. Because no IV contrast dye is used, this exam focuses on the natural differences in tissue appearance to identify problems such as fractures, arthritis, inflammation, or soft tissue injury.

What the results mean (in plain language): A radiologist reviews the images and sends a report to your clinician. Results may be described as:

Normal (no clear structural cause of symptoms), or abnormal findings such as bone bruising or fracture, cartilage wear from arthritis, swelling or fluid suggesting inflammation, tendon or muscle strain/tear, or other changes that help explain joint pain. MRI results don’t “measure” a single number like a blood test—rather, they show detailed anatomy and signs of injury or disease that guide diagnosis and treatment planning.

When & why it's usually done

Your clinician may order an MRI of the hip without contrast when symptoms suggest a problem inside or around the hip joint that may not be fully explained by a physical exam or X-ray. It is especially useful for evaluating soft tissue and early bone changes that can be missed on plain radiographs.

Common reasons include:

Persistent hip or groin pain (especially when it limits walking, sports, or daily activities), pain that worsens with movement, or pain that continues despite rest, physical therapy, or medication.

Suspected fracture or bone injury after a fall, sports impact, or accident—particularly when an X-ray is normal but symptoms strongly suggest a fracture or stress fracture.

Arthritis evaluation (such as osteoarthritis or inflammatory arthritis) when you have stiffness, reduced range of motion, clicking, or deep joint pain, and your care team needs a clearer picture of cartilage, joint lining, and surrounding tissue.

Soft tissue injury concerns, including suspected tendon or muscle strain/tear, bursitis, or irritation around the hip that can cause lateral hip pain or pain with stairs and side-lying.

Mechanical symptoms such as catching, locking, or painful clicking—sometimes related to labral or cartilage injury and other structural causes of hip joint pain.

Risk factors that may increase the chance of hip injury or degeneration, such as high-impact sports, repetitive overuse, older age, osteoporosis risk, prior hip surgery, or a history of inflammatory joint disease.

This MRI is done without IV contrast when contrast is not necessary for the clinical question or when a patient prefers to avoid IV dye. In some situations (for example, certain tumor evaluations or specific labral assessments), a clinician may recommend contrast or a specialized MRI approach, but many common hip problems can be evaluated well without it.

Common diseases related to it

• Hip osteoarthritis (degenerative joint disease)
• Inflammatory arthritis (e.g., rheumatoid arthritis, psoriatic arthritis)
• Occult fracture (fracture not seen on X-ray) and hip stress fracture
• Bone contusion (bone bruise) after trauma
• Avascular necrosis (osteonecrosis) of the femoral head
• Femoroacetabular impingement (FAI)
• Labral tear and cartilage injury (chondral defects)
• Trochanteric bursitis and gluteal tendinopathy (greater trochanteric pain syndrome)
• Tendinitis, tendon tears, or muscle strains around the hip (e.g., iliopsoas, gluteal muscles, adductors)
• Hip joint effusion and synovitis (fluid and inflammation within the joint)
• Septic arthritis or osteomyelitis (when clinical suspicion is present; MRI can help assess extent)
• Sports-related and overuse injuries causing hip and groin pain

Health goals where it may help

• Identify the cause of ongoing hip, groin, or buttock pain to guide a targeted treatment plan
• Support an orthopedic evaluation for suspected musculoskeletal disorders affecting the hip joint
• Confirm or rule out fractures or stress injuries early to prevent worsening damage and speed safe recovery
• Assess arthritis severity and joint cartilage health to plan pain management, physical therapy, or surgical options
• Evaluate soft tissue injury (tendons, muscles, bursae) to select appropriate rehabilitation and reduce re-injury risk
• Monitor progression or healing of a known hip condition after rest, therapy, or other treatment
• Help determine readiness to return to work, sports, or daily activities after hip injury
