MRI vs. Ultrasound: What’s the Difference & Which One Do You Need?
When your doctor recommends medical imaging, it’s normal to wonder which type of scan you need — and why. Two of the most common imaging exams are MRI and ultrasound, but they work very differently and are used to evaluate different parts of the body.
At Evolution Imaging in Edmond, OK, we offer both MRI and ultrasound in a comfortable, spa-like environment designed to ease anxiety and provide a better overall patient experience. Here’s a simple breakdown to help you understand the differences — and feel confident heading into your appointment.
What Is an MRI?
An MRI (Magnetic Resonance Imaging) uses magnetic fields and radio waves to create highly detailed images of organs, soft tissues, and bones. It’s non-invasive, radiation-free, and one of the most precise imaging tools available.
What MRI Is Best For:
MRI provides exceptional detail, making it the preferred option for evaluating:
Brain & spinal cord
Joints and soft tissues (shoulder, knee, hip, ankle, wrist)
Muscles, ligaments & tendons
Abdominal organs
Pelvic structures
Disc injuries or nerve impingement
Why Patients Choose MRI at Evolution Imaging
Our 1.5T Siemens MAGNETOM Aera features a 70 cm wide bore (reducing claustrophobia), fast scan times, and noise-reducing technology. Patients receive:
Noise-canceling headphones
Choice of music
Warm blankets
Gentle lighting
A relaxing, spa-like environment
MRI is ideal when your provider needs a deep, detailed look at an area of concern.
What Is an Ultrasound?
An ultrasound uses sound waves to create real-time images of structures inside the body. It’s safe, painless, radiation-free, and commonly used for both diagnostic and pregnancy-related imaging.
What Ultrasound Is Best For:
Ultrasound is especially effective for:
Pregnancy & prenatal imaging
Abdominal exams (liver, gallbladder, kidneys)
Pelvic exams
Thyroid & neck imaging
Vascular imaging (blood flow, DVT screening)
Musculoskeletal evaluations
Guided injections or procedures
Why Patients Choose Ultrasound at Evolution Imaging
Our skilled sonographers provide both medical and OB ultrasound services, including 2D, 3D, and 4D options for expectant parents. Patients appreciate:
Same-day or next-day availability
Comfortable private ultrasound suites
Clear communication throughout the exam
Safe, radiation-free imaging
Ultrasound is ideal when your provider needs a quick, dynamic image of organs, soft tissue, or blood flow.

Both imaging types are safe — your provider chooses based on what they need to see.
How Your Provider Decides Which Scan You Need
Your doctor will consider:
Your symptoms
Your medical history
The area of concern
How detailed the images need to be
Whether real-time movement needs to be observed
A good rule of thumb:
👉 MRI is best for detailed, internal structures like joints, the brain, or the spine.
👉 Ultrasound is best for organs, pregnancy, blood flow, and real-time evaluation.
