An MRI appointment should give you a clear answer, not add to the uncertainty around persistent pain. If you are wondering how to choose an open MRI scan, look beyond the word “open”. The right scan depends on the part of your body being assessed, the clinical question, the quality of the images required and how comfortably you can stay still during the examination.
For people with knee, shoulder, neck, lower back or ankle symptoms, an open MRI can be a reassuring option, particularly if a traditional enclosed scanner causes anxiety or is difficult because of mobility, pain or body shape. However, comfort must be matched with the right diagnostic standard. A scan is only useful when it provides the detail your clinician needs to make a confident treatment decision.
Start with the reason for your MRI
The first question is not simply whether an open scanner is available. It is: what does your clinician need to see?
MRI is especially valuable for examining soft tissues that do not show clearly on an X-ray. In the knee, this may include the meniscus, cruciate ligaments, cartilage, tendons and bone marrow. In the shoulder, it can help assess the rotator cuff, labrum, biceps tendon and joint surfaces. MRI is also commonly used to investigate nerve compression or disc changes in the neck and lumbar spine.
The scan should be requested with a specific clinical concern in mind. For example, the imaging requirements for suspected ACL damage after a sporting injury may differ from those for longstanding arthritis, a possible rotator cuff tear or persistent pain following previous surgery. A good service will make sure the referral question is clear before choosing the scanning approach.
If you have already had an X-ray, ultrasound or previous MRI, take this into account. These tests may answer different questions, and a specialist can advise whether another MRI is likely to change your treatment plan rather than simply repeat information you already have.
How to choose an open MRI scan: comfort and image quality
“Open MRI” is used to describe several types of scanner. Some are open at the sides, while others have a wider, shorter tunnel than a conventional closed MRI. Upright MRI systems allow scanning while sitting or standing for selected examinations. The design can make a major difference to how the experience feels, but it does not automatically mean every open scanner is equally suitable for every condition.
Image quality is affected by the scanner, the body area being scanned, the sequences used and your ability to remain still. Higher-field scanners can often produce more detailed images, which may be particularly helpful for small structures or complex diagnostic questions. Yet an enclosed scanner is not always the best practical choice if claustrophobia, severe pain or limited mobility means you cannot tolerate it long enough to complete the scan properly.
This is the balance to discuss with the provider. Ask whether their open MRI is suitable for the specific joint or spinal area being investigated, and whether the scan protocol is designed for that condition. For many musculoskeletal problems, an appropriately planned open MRI can provide useful, high-quality diagnostic information while being considerably easier to tolerate.
Do not feel that you must choose between being comfortable and receiving proper clinical care. The aim is to select a setting in which you can complete the examination safely and still obtain images that answer the question.
Ask what position you will be scanned in
Position matters, particularly when pain makes certain movements difficult. A knee scan may require you to lie with the leg positioned in a particular way. A shoulder scan can involve supporting the arm carefully to reduce movement. For neck and lower back imaging, lying flat may be uncomfortable if your symptoms worsen in that position.
Ask the team to explain how you will be positioned, how long you will need to stay still and whether cushions or supports can be used. If you struggle to lie flat, have restricted shoulder movement, or are concerned about getting on and off the scanner table, say so before booking. A patient-centred imaging service will plan around these practical issues wherever possible.
Check the clinical pathway, not just the scanner
A scan is one stage of diagnosis, not the end of it. Before booking, ask who will review the images, when you will receive the results and what happens next. Waiting for a report without an explanation can leave patients with more questions than answers.
Look for a service where MRI findings are considered alongside your symptoms, examination and medical history. A meniscal tear, cartilage change or tendon abnormality may be visible on a scan, but the significance varies from person to person. Not every finding needs surgery, and not every painful joint requires an injection. The best treatment plan is based on the complete picture.
At Droitwich Knee Clinic, a one-stop assessment can combine a specialist consultation, appropriate imaging and a same-day discussion of the findings where suitable. This can be particularly helpful for patients travelling from across Worcestershire, Birmingham or further afield, and for anyone keen to avoid separate appointments and unnecessary delays.
Questions to ask before you book
A short conversation before your appointment can help you choose with confidence. Ask whether the scanner is appropriate for your body area and suspected condition, how long the scan will take, and whether the images will be formally reported by an experienced radiologist.
You should also ask when the results will be available and whether a clinician with musculoskeletal expertise will explain what they mean for you. If treatment may be needed, find out whether this can be discussed promptly or whether you will be referred elsewhere.
Practical questions matter too. Check the location, parking, accessibility and whether you may bring someone with you. Ask if you can listen to music, use a call bell, or speak to the radiographer during the scan. These details can make the experience feel far more manageable, especially if you are anxious.
If cost is relevant, confirm what is included. A quoted price may cover the scan alone, while another service may include the consultation, report and review appointment. Comparing like for like helps avoid surprises.
Be honest about claustrophobia, pain and mobility
Many people delay an MRI because they have felt trapped or uncomfortable in a previous scanner. Tell the provider if you have claustrophobia, panic attacks, difficulty lying still, a painful shoulder, severe back pain or limited mobility. This is useful clinical information, not an inconvenience.
An open or more spacious scanner may be a better option, but preparation also helps. Knowing what the machine sounds like, how long each sequence lasts and that you can communicate with the radiographer can reduce anxiety. Some patients find it helpful to practise slow breathing or to close their eyes before they enter the scanning area.
Sedation is occasionally considered for severe anxiety, but it is not appropriate or necessary for everyone and may involve additional arrangements. Discuss this early rather than arriving on the day hoping to manage without support.
Safety screening is essential
MRI uses a powerful magnetic field, so every patient must complete a safety questionnaire. Inform the imaging team about any pacemaker, neurostimulator, cochlear implant, aneurysm clip, metal fragments, joint replacement, surgical clips or previous operations. Many modern implants are MRI-compatible, but they still need to be checked against the scanner and the planned examination.
Also mention pregnancy, kidney problems, allergies and any possibility that contrast dye may be required. Most musculoskeletal MRI scans are performed without contrast, although there are situations where it is useful. The team should explain why it is being considered and answer any safety questions clearly.
Remove jewellery, watches, hearing aids, bank cards and clothing with metallic fastenings before scanning. Following these instructions protects you and helps prevent artefacts that can reduce image quality.
Choose clarity over a quick booking
The fastest appointment is not always the most useful one if the images cannot answer your clinician’s question or there is no clear plan after the report arrives. Equally, there is little benefit in waiting weeks for a scan that could be completed sooner in a suitable open setting.
Choose a provider that listens to your concerns, explains the type of scanner being used and connects the result to a practical next step. The right open MRI scan should leave you with more than pictures of a painful joint or spine – it should move you closer to an informed decision and a realistic plan to get back to comfortable movement.
