This guide explains how an MRI works and how it supports diagnosis. MRI uses magnets and radio waves, not Xrays, so it produces detailed images of both bone and soft tissue in the body without ionizing radiation. Nearly 40 million exams happen each year in the United States, and most are painless.
What to expect during MRI
Scanner choices include traditional, wide-bore, and open models to improve comfort and access. Typical appointments last about 20–90 minutes. Patients usually may eat and take routine medication unless told otherwise.
Clinics provide gowns, remove metal items for safety, and screen for implants or prior surgeries before entry to the MRI suite. Technologists stay in touch through the exam, and sedation options are available for anxiety; a ride home is required if sedated.
Key Takeaways
MRI imaging produces detailed, radiation-free images for clear diagnosis.
Choose a scanner option—traditional, wide-bore, or open—based on comfort needs.
Prepare by removing metal and following screening questions for safe care.
Most people resume normal activity after the scan; sedated patients need post-procedure support.
Results are shared with your doctor and local scheduling is available Monday–Friday, 9am–5pm.
Magnetic resonance imaging basics: how MRI scans work and when they’re used
Modern magnetic resonance scanners create sharp pictures of soft tissues by aligning hydrogen atoms in the body and reading their returning signals. A large magnet, radio waves, and a computer combine to produce detailed images without ionizing radiation.
Common uses include brain and spine exams for tumors, stroke, and multiple sclerosis. Clinicians also order scans for joints, ligaments, muscles, and abdominal organs such as the liver and pancreas.
Contrast-enhanced resonance imaging with gadolinium highlights tumors, inflammation, infection, and blood flow.
Cardiac imaging assesses chamber size, valve function, and myocardial scarring.
Advanced 3T machines shorten scan time and improve image clarity for complex conditions.
Scanner type | Comfort | Image quality | Best uses |
Closed-bore | Lower comfort, more enclosed | Highest | Neuro, small-structure, cardiac detail |
Wide-bore | Improved comfort | High | General body, most joint imaging |
Open MRI | Best for claustrophobia | Moderate | Large patients, comfort-focused exams |
MRI vs CT: magnetic resonance imaging generally gives clearer soft-tissue pictures and images without radiation. CT may be preferred for urgent trauma, detailed bone injuries, or when implants are not compatible with magnetic resonance.
How to prepare before your MRI appointment
A short screening and a few clothing changes make the mri process safer and more efficient.
Metal and implants screening
Before the scan, staff ask focused questions about prior surgeries and any metal in or on the body. Inform the technologist about pacemakers, stents, joint replacements, aneurysm clips, insulin pumps, neurostimulators, or medicine patches.
Medications, food, and clothing
Patients may usually eat and take their regular medication unless a doctor says otherwise. Remove all jewelry, watches, hairpins, and makeup that may contain tiny metal particles.
Many centers require changing into a provided gown because some fabrics have metal fibers that can heat during the exam.
Claustrophobia and sedation options
If anxiety is a concern, ask about wide-bore or open options and about oral or IV sedation. Plan extra time for consent and monitoring when sedation may need scheduling.
Arrival checklist
Arrive early to complete forms and review medical history with the imaging center staff.
Bring a list of implants and recent procedures; model numbers help confirm compatibility.
Arrange a ride home if sedation is planned and secure personal items before entering the room.
What to expect during MRI
A technologist prepares the bed, coils, and positioning aids to help you stay comfortable and still.
Inside the room and the technologist’s role
The technologist positions you on a padded bed with surface coils shaped for the area being imaged. They explain each step, answer questions, and remain in two-way contact for safety and comfort.
Sounds, communication, and staying still
Expect rhythmic thumps and clicks as the machine runs. Earplugs or noise-reducing headphones are provided and a call button stays in your hand so you can alert staff if needed.
Staying still matters because motion blurs images. For chest or belly pictures, brief coached breath-holds help capture clear shots of organs and vessels.
Timing, comfort, and contrast
Most scans take between 20 and 90 minutes, with some sequences lasting only a few minutes. Blankets and cushions improve comfort during longer exam periods.
If contrast is ordered, an IV is placed in the hand or arm. Gadolinium contrast enhances visualization of tumors, inflammation, infection, and blood flow; severe reactions are rare.
Feature | Typical minutes | Why it matters |
Brain/spine | 30–60 | High-detail images for neurologic questions |
Extremity | 20–40 | Focused pictures for joints and soft tissue |
Abdomen with contrast | 40–90 | Multiphase views of organs and vessels |
After your MRI: recovery, results, and scheduling your next steps
When the technologist confirms images are complete, staff walk patients through brief recovery steps and any immediate care notes. Most people change, gather belongings, and return to normal activity the same day.
Right after the scan
If no sedation was given, driving is fine and normal tasks may resume. If sedation or anxiety medication was used, do not drive home; arrange a ride home and plan light activity while effects wear off.
Receiving results and follow-up
A radiologist reviews the scans and sends a formal report to the ordering doctor. The referring clinician discusses findings, next tests, and care for any conditions under evaluation.

Safety, eligibility, and MRI machine types to reduce anxiety
Understanding device limits and scanner types helps patients feel safer and more prepared. Magnetic resonance imaging is safe for most people when standard screening and checks are followed. Clear steps and staff communication reduce worry and improve cooperation.
Who should avoid scans or take extra precautions
Patients with certain implants need focused review before an exam. Older pacemakers, some defibrillators, specific aneurysm clips, many cochlear implants, and some vascular coils may be unsafe unless labeled MRI-safe or conditional.
Share implant model details so technologists can confirm compatibility. Pregnant patients usually avoid gadolinium contrast unless a pressing clinical need is documented with obstetric input.
Choosing the right scanner
Scanner type affects comfort and image quality. Closed-bore systems give the best resolution, wide-bore offers a balance of comfort and clarity, and open machines create larger spaces but may lower image detail.
Technologists select an mri machine and protocol based on anatomy, device constraints, and the diagnostic question. If magnetic resonance imaging cannot be used safely, alternatives like CT, ultrasound, or nuclear studies may be recommended.
Safety checks and metal screening happen before entering magnet zones.
Discuss anxiety plans: larger bore choices, relaxation techniques, or medication.
Staff weigh device risk and imaging needs to pick the safest scanner and protocol.
Conclusion
An mri scan gives clear, radiation-free pictures that help your doctor assess conditions of the brain, heart, spine, and other parts of the body.
Scans are tailored by a technologist, run inside a controlled room, and use the right machine for each clinical question. Most tests take about 20–90 minutes, and the images help guide next steps in care.
If contrast or medication may need use, the team explains benefits and monitoring. Hospitals and outpatient centers coordinate reports so your doctor receives clear pictures and follow-up recommendations promptly.
FAQ
Complete guide: what to expect before, during and after your MRI
This guide covers preparation, the scan process, and post-scan steps. It explains screening for metal and implants, claustrophobia options, contrast use, typical scan times by body area, and how results reach your referring clinician.
Magnetic resonance imaging basics: how MRI scans work and when they’re used
MRI uses strong magnetic fields and radio waves to create detailed images of soft tissues, organs, blood vessels, and bones. It’s commonly used for brain, spine, joint, abdominal, pelvic, and vascular studies when clear soft-tissue contrast is needed without ionizing radiation.
What can MRI show inside your body: brain, spine, joints, organs, vessels, and more?
MRI reveals stroke, tumors, spinal disc issues, ligament and tendon injuries, liver or kidney lesions, cardiac structure, and vessel abnormalities. It often detects subtle changes that CT or X-ray miss, especially in soft tissue.
MRI vs. CT scan: no radiation, clearer soft-tissue images, and when CT may be used instead
MRI provides superior soft-tissue detail and uses no ionizing radiation. CT is faster, better for acute trauma, bone detail, or when MRI is contraindicated. Your physician selects the modality based on clinical needs.
How should patients prepare before an MRI appointment?
Arrive with completed forms and medical history, bring relevant implant documentation, leave jewelry and metallic items at home, wear comfortable clothing or the provided gown, and follow any fasting orders if contrast is planned.
Metal and implants screening: pacemakers, stents, joint replacements, aneurysm clips, and patches
Inform staff about pacemakers, ICDs, cochlear implants, aneurysm clips, metal fragments, implantable pumps, or recent tattoos. Some implants are MRI-safe, others need special protocols or may disqualify a scan.
What about medications, food, and clothing before a scan?
Continue prescribed medications unless told otherwise. For contrast exams, fasting for a few hours may be requested. Remove jewelry, watches, piercings, and makeup. Wear loose, metal-free clothes or a gown supplied by the facility.
Claustrophobia and sedation options: open and wide-bore MRI, oral sedatives, and IV sedation planning
Patients with anxiety can ask for wide-bore or open MRI units, listen to music or use headphones, or receive oral or IV sedation. Discuss sedation, transportation needs, and medical history with your provider before the appointment.
Arrival checklist: forms, medical history, changing rooms, secure storage, and arranging a ride if sedated
Bring ID and insurance, complete screening forms, disclose implants and allergies, change into a gown if needed, store personal items in lockers, and arrange a companion if sedation is used since driving may be restricted.
Inside the MRI room: padded table, coils, moving bed, and the role of your technologist
The technologist positions you on a padded table and places coils near the area being imaged. The table slides into the scanner, and the technologist monitors you from the control room while communicating via intercom.
Sounds and communication: thumps and clicks, earplugs or headphones, and the call button
MRI produces tapping or knocking noises during sequences. Facilities provide ear protection and often offer music. You’ll receive a call button to alert staff if you need assistance during the scan.
Staying still and breath-holds: why motion matters and how your technologist guides you
Motion blurs images. Technologists instruct you to remain still and may ask for brief breath-holds for chest, abdomen, or cardiac imaging. Clear communication and positioning aids improve image quality.
Timing and comfort: typical scan minutes by body area, blankets, and positioning aids
Scan length varies: joint scans may take 20–30 minutes, spine or brain 30–45 minutes, and complex studies longer. Technologists use cushions and blankets to increase comfort and reduce movement.
With and without contrast: IV setup, gadolinium safety, and what contrast helps visualize
Contrast (gadolinium) is given via IV for better visualization of blood vessels, inflammation, tumors, and active lesions. It’s generally safe, but patients with severe kidney disease need evaluation before administration.
Right after your scan: changing, driving considerations with sedation, and returning to normal activity
After non-sedated exams, patients change and resume normal activities. If sedated, recovery time varies and someone must drive you home. Staff provide post-sedation instructions and monitor until stable.
When and how you’ll get results: image review, radiology reports, and coordination with your doctor
A radiologist reviews images and issues a report, usually within 24–72 hours for routine exams. Your referring physician discusses results and next steps. Urgent findings are communicated immediately.
